Virginia Tech, Children’s National Hospital award $100,000 to fund collaborative cancer research pilot projects

January 13, 2021

This pilot research program represents a growing academic research partnership between Children’s National and Virginia Tech. Last year, the two institutions announced that Virginia Tech will establish a biomedical research facility on the Children’s National Research & Innovation Campus.

Children’s National Hospital and Virginia Tech have awarded two $50,000 one-year pilot grants to multi-institutional teams of scientists for pediatric brain cancer research.

The inter-institutional program, which launched in December, promotes cross-disciplinary collaborations among researchers at both institutions. At Virginia Tech, the program is part of the Virginia Tech Cancer Research Alliance. Financial support for the program was provided by the Offices of the Physician-in-Chief and Chief Academic Officer at Children’s National, and by Virginia Tech’s Office of the Vice President for Health Sciences and Technology.

“We were delighted to see so many innovative and competitive research proposals for our first round of pilot grants in the area of brain cancer. By forging new research collaborations with our partners at Children’s National, we hope to make major strides in addressing one of the most common and devastating groups of cancers in children,” said Michael Friedlander, Virginia Tech’s vice president for health sciences and technology, and the executive director of the Fralin Biomedical Research Institute at VTC. “The pilot funding will bootstrap several programs to be able to acquire ongoing sustainable funding by providing the opportunity to test novel high impact ideas for new strategies for treating these disorders. There are simply too few good options for children in this space now and this partnership can change that for the better.”

The collaborative research initiative began through an agreement between the Fralin Biomedical Research Institute and the Children’s National Research Institute. The collaborative teams formed through a series of interactive discussions among Virginia Tech’s Cancer Research Alliance faculty members from the university’s Blacksburg and Roanoke campuses, and Children’s National’s neuro-oncology researchers.

“I am extremely excited by this collaboration between VT and CNH that is focused on pediatric brain tumors which is such an area of unmet need,” said Catherine Bollard, M.D., M.B.Ch.B.,, director of Children’s National’s Center for Cancer and Immunology Research. “I am confident that the funded proposals will soon advance our understanding of pediatric brain tumors and, more importantly, facilitate more joint efforts between two world-class institutions which is especially timely with the development of the Children’s National Research & Innovation Campus.”

Yanxin Pei, Ph.D., an assistant professor in the Center for Cancer Immunology Research at Children’s National, and Liwu Li, Ph.D., a professor of biological sciences in Virginia Tech’s College of Science, were awarded one of the pilot research grants to study how white blood cells called neutrophils are involved in metastatic MYC-driven medulloblastoma, an aggressive type of brain tumor in children that often resists conventional radiation and chemotherapies.

Yuan Zhu, Ph.D., the Gilbert Family Professor of Neurofibromatosis Research at Children’s National, and Susan Campbell, Ph.D., an assistant professor of animal and poultry sciences in Virginia Tech’s College of Agriculture and Life Sciences, were awarded funds to study glioma-induced seizures in mice with a genetic mutation that inhibits the production of P53, a key protein involved in suppressing cancer cell growth and division.

The successful applicants will receive funding starting this month and are expected to deliver preliminary data to support an extramural research application by 2024.

This pilot research program represents a growing academic research partnership between Children’s National and Virginia Tech. Last year, the two institutions announced that Virginia Tech will establish a biomedical research facility on the Children’s National Research & Innovation Campus. It will be the first research and innovation campus in the nation focused on pediatrics when it opens later this year and will house newly recruited teams of pediatric brain cancer researchers.

A lifetime of achievements: Roger Packer, M.D.

December 24, 2020

Over the years, Dr. Packer and his team in Washington, D.C., have made meaningful contributions to children all around the world diagnosed with childhood brain tumors, including medulloblastoma and gliomas.

Earlier in December, Roger Packer, M.D., senior vice president of the Center for Neurosciences and Behavioral Medicine at Children’s National Hospital, received the 2020 Lifetime Achievement Award from the International Symposium on Pediatric Neuro-Oncology at the meeting organized in Karuizawa, Japan. The prestigious recognition is a testament to the years of commitment and dedication Dr. Packer has devoted to the care of children with brain tumors and as such, have placed him as a top leader.

This award is a recognition of how the field has grown since the first International Symposium on Pediatric Neuro-Oncology Dr. Packer organized in Seattle in 1989. “It grew from a small gathering of investigators to now a multidisciplinary group of over 2,000 investigators,” Dr. Packer says.

Over the years, Dr. Packer and his team in Washington, D.C., have made meaningful contributions to children all around the world diagnosed with childhood brain tumors, including medulloblastoma and gliomas. These findings have contributed to an increase of the survival rate from 50% to over 80% for children with medulloblastoma. In addition, his contributions have led to newer molecular targeted therapies and improved the quality of life of children who are long-term survivors.

“The field, especially in the last decade, rapidly transitioned to a more biologically informed field,” Dr. Packer explains. “We are now utilizing new, exciting discoveries in biology and genetics to inform new approaches to treatment. This kind of transition gives us great hope for the future.”

In his early career, Dr. Packer worked with two neuro-oncology patients who died and would impact his decision to further study this field. At that time, there was minimal understanding of the nature of neuro-oncology diseases or how to best treat them. As a neurologist, he was frustrated by the lack of understanding and as a pediatrician, he was frustrated at the lack of ability to do success management.

“I saw this as a gap in my personal knowledge and found that the field was struggling to come up with new answers and new approaches,” he says. “But at the same time other, advances were being made in child cancer care, such as with leukemia. However, there was no wide focus on pediatric brain tumors.”

Combining his knowledge of neurology with his curiosity and relying on other leaders that surrounded him in the same field, Dr. Packer worked on driving this new work forward. Today, he is still heavily involved in the development of treatment protocols that are increasingly transitional for a variety of brain tumors, including low-grade and high-grade gliomas.

“With the help of our great colleagues at Children’s National, we continue to try to develop new means to treat these tumors, including immunological approaches and the incorporation in the use of novel means, such as low-intensity and high-intensity focused ultrasound,” he says. “We also have an excellent multidisciplinary team at Children’s National that has grown over the last decade some of whom are acknowledged national leaders in the fields of brain tumors, clinical research and clinical care. We also have a robust program focusing on the neurocognitive outcome of children and ways to intervene to ameliorate intellectual compromise and improve quality of life.”

Epigenetics and pediatric brain tumors

December 23, 2020

Over the last two decades the critical role of epigenetics in cancer biology has evolved significantly. In parallel, our understanding of the biology of many pediatric brain tumors and the central role of alterations in their epigenetic regulation has become an important area of discovery.

In an editorial in a special issue of the Journal of Neuro-Oncology, Roger Packer, M.D., senior vice president of the Center for Neurosciences and Behavioral Medicine at Children’s National Hospital, looks at understanding the role of epigenetics and how they will further characterize pediatric brain tumors, open new therapeutic avenues for treatment and lead to true breakthroughs and cures for children.

Update on pediatric brain tumors

December 22, 2020

Over the last five years, there has been tremendous growth in the field of pediatric neuro-oncology with increasing understanding of the genetic and epigenetic heterogeneity of central nervous system (CNS) tumors. Attempts are underway to translate these insights into tumor-specific treatments. A recent review article in Current Neurology and Neuroscience Reports by Roger Packer, M.D., senior vice president of the Center for Neurosciences and Behavioral Medicine at Children’s National Hospital, provided an update on the current landscape of pediatric brain tumors and the impact of novel molecular insights on classification, diagnostics and therapeutics.

Primary cilia safeguard cortical neurons from environmental stress-induced dendritic degeneration

December 21, 2020

Fetus and neonates are under the risk of exposure to various external agents, such as alcohol and anesthetics taken by the mother. However, primary cilia can protect neurons by activating cilia-localized molecular signaling that inhibits degeneration of neuronal processes, according to the study’s findings.

A new study led by Kazue Hashimoto-Torii, Ph.D. and Masaaki Torii, Ph.D., both principal investigators for the Center for Neuroscience Research at Children’s National Hospital, found that primary cilia – tiny hair-like protrusions from the body of neuronal cells – protect neurons in the developing brain from adverse impacts of prenatal exposure.

Fetus and neonates are under the risk of exposure to various external agents, such as alcohol and anesthetics taken by the mother. However, primary cilia can protect neurons by activating cilia-localized molecular signaling that inhibits degeneration of neuronal processes, according to the study’s findings.

“Remarkably, the developing brain is equipped with intrinsic cell protection that helps to minimize the adverse impacts of to various external agents,” said Dr. Hashimoto-Torii. “However, the mechanisms of such protection have been unclear. Our study provides the first evidence that the tiny hair-like organelle protects neurons in the perinatal brain from adverse impacts of such external agents taken by the mother.”

The findings suggest that subtle alterations in primary cilia due to genetic conditions may lead to various neurodevelopmental disorders if combined with exposure to external agents from the environment. The findings also suggest that ciliopathy patients who have abnormal ciliary function due to genetic causes may have increased risk of abnormal brain development upon exposure to external agents.

“Clarifying diverse roles of cilia provides essential information for clinicians and patients with potential deficits in primary cilia to take extra precautions to avoid the risks for long-term negative impacts of external factors,” Dr. Torii explained. “We hope that further studies will define the whole picture of cilia-mediated neuroprotection and help us to advance our understanding of its importance in the pathogenesis of neurodevelopmental disorders.

This may ultimately lead to the development of treatment for various neurodevelopmental disorders,” he added.

The uniqueness of the study stems from the investigation of the role of cilia in brain development at the risk of exposure to various external factors that occur in the real world. Little is known about how the normal and abnormal brain development progresses in an environment where many external factors interact with intrinsic cellular mechanisms.

The study is a collaboration with researchers at Yale University and Keio University, Japan. Other Children’s National researchers who contributed to this study include Seiji Ishii, Ph.D.; Nobuyuki Ishibashi, M.D.; Toru Sasaki, M.D., Ph.D.; Shahid Mohammad, Ph.D.; Hye Hwang; Edwin Tomy; and Fahad Somaa.

Family love and the right care for neurofibromatosis type 1 give Maddox a fresh start

December 14, 2020

Maddox and his family in early 2020.

13-year-old Maddox Gibson is learning to cook. He says he wants to be a chef and wants to make meals for people who need it most — the homeless and the hungry.

It makes sense that he’s eager to help people who need it. As a young child growing up in a group home in his native country of China, he knows firsthand how important that support can be. In 2017 at age 10, he found his own endless supply of love and support when he met and was adopted by the Gibson family.

Zhen Chao, now called Maddox, was born in China with a genetic condition called neurofibromatosis type 1 that can cause painful or disfiguring tumors called plexiform neurofibromas. Zhen Chao had two on his head when he arrived — on his scalp and on his left optic nerve — which had been largely untreated for most of his life in China. On top of that, his right leg had been fractured and not fixed properly years before, causing him pain and weakness that left him wheelchair bound.

Adoptive mom Lindsey, a registered nurse, knew he would need special care to meet all the unique challenges he faced, and she’d done her homework — he needed the expertise of Miriam Bornhorst, M.D., and the Gilbert Family Neurofibromatosis Institute at Children’s National Hospital to help him thrive in his new life in the U.S. Since shortly after he came to the U.S., Lindsey has been driving Maddox the 6-plus hours from their home in North Carolina to Washington, D.C., regularly, to get care for all of his health challenges.

Maddox’s optic neurofibroma was too large when he arrived at Children’s National for a simple surgical removal. Due to her role as the lead investigator on a cutting edge clinical trial for the orphan drug selumetinib — a so-called MEK inhibitor that has shown early promise at reducing the cell growth of tumors like plexiform neurofibromas, Dr. Bornhorst enrolled Maddox in a compassionate use program for the drug, an opportunity that is not widely available. The drug was initially developed for something completely different — treatment of melanoma and non-small cell lung cancer in adults–but has been adapted through its FDA orphan drug designation for pediatric clinical trials in NF1. In the time since Maddox started taking it, it was approved for use in NF1 patients by the FDA.

The trial drug did its job — in late 2019, Maddox’s tumor had shrunk enough that chief neurosurgeon Robert Keating, M.D., and plastic surgeon Michael Boyajian, M.D., were able to successfully remove it. Follow-up procedures led by that team have also worked to repair the tissue that was impacted by the optic neurofibroma.

In addition to treatment of his neurofibromas, Maddox and his mom are able to see every service they need during one stay in D.C. The Neurofibromatosis Institute works closely across specialties, so his corrective surgery for his leg from Children’s chief of orthopaedics, Matthew Oetgen, M.D., MBA, in September 2019. He was assessed and prescribed physical therapy early in the process and even before surgery, so now he’s stronger than ever and walking. Learning difficulties, including autism and ADHD are common in NF1 patients, and so the NF Institute’s neuropsychology team has evaluated him and worked with the family to find resources and strategies near home that will support him. It should be noted, those learning difficulties only became apparent after Maddox taught himself English from scratch in only two years’ time with the help of his school’s ESOL program.

This kind of full spectrum care, from clinical assessment to surgical treatment and psychological supports, is crucial to the lives of patients with neurofibromatosis type 1 and is only available at a pediatric specialty care institution like Children’s National. The hospital has gathered some of the preeminent researchers, surgeons, and physicians within the NF Institute to make sure that the care families will travel hundreds of miles to receive is the best possible, using the latest evidence-based treatments for every challenge they face.

Though his care and follow-ups will continue at Children’s National Hospital and his condition may pose new challenges in the future, for now, Maddox is able to focus on exploring new things and doing what he loves — playing outdoors with his family, learning to cook and building with Legos.

Maternal anxiety affects the fetal brain

December 7, 2020

Anxiety in gestating mothers appears to affect the course of brain development in their fetuses, changing neural connectivity in the womb, a new study suggests.

Anxiety in gestating mothers appears to affect the course of brain development in their fetuses, changing neural connectivity in the womb, a new study by Children’s National Hospital researchers suggests. The findings, published Dec. 7, 2020, in JAMA Network Open, could help explain longstanding links between maternal anxiety and neurodevelopmental disorders in their children and suggests an urgent need for interventions to diagnose and decrease maternal stress.

Researchers have shown that stress, anxiety or depression in pregnant mothers is associated not only with poor obstetric outcomes but also social, emotional and behavioral problems in their children. Although the care environment after birth complicates the search for causes, postnatal imaging showing significant differences in brain anatomy has suggested that these problems may originate during gestation. However, direct evidence for this phenomenon has been lacking, says Catherine Limperopoulos, Ph.D., director of the Developing Brain Institute at Children’s National.

To help determine where these neurological changes might get their start, Dr. Limperopoulos, along with staff scientist Josepheen De Asis-Cruz, M.D., Ph.D., and their Children’s National colleagues used a technique called resting-state functional magnetic resonance imaging (rs-fMRI) to probe developing neural circuitry in fetuses at different stages of development in the late second and third trimester.

The researchers recruited 50 healthy pregnant volunteers from low-risk prenatal clinics in the Washington, D.C. area who were serving as healthy “control” volunteers in a larger study on fetal brain development in complex congenital heart disease. These study participants, spanning between 24 and 39 weeks in their pregnancies, each filled out widely used and validated questionnaires to screen for stress, anxiety and depression. Then, each underwent brain scans of their fetuses that showed connections between discrete areas that form circuits.

After analyzing rs-fMRI results for their fetuses, the researchers found that those with higher scores for either form of anxiety were more likely to carry fetuses with stronger connections between the brainstem and sensorimotor areas, areas important for arousal and sensorimotor skills, than with lower anxiety scores. At the same time, fetuses of pregnant women with higher anxiety were more likely to have weaker connections between the parieto-frontal and occipital association cortices, areas involved in executive and higher cognitive functions.

“These findings are pretty much in keeping with previous studies that show disturbances in connections reported in the years and decades after birth of children born to women with anxiety,” says Dr. De Asis-Cruz. “That suggests a form of altered fetal programming, where brain networks are changed by this elevated anxiety even before babies are born.”

Whether these effects during gestation themselves linger or are influenced by postnatal care is still unclear, adds Dr. Limperopoulos. Further studies will be necessary to follow children with these fetal differences in neural connectivity to determine whether these variations in neural circuitry development can predict future problems. In addition, it’s unknown whether easing maternal stress and anxiety can avoid or reverse these brain differences. Dr. Limperopoulos and her colleagues are currently studying whether interventions that reduce stress could alter the trajectory of fetal neural development.

In the meantime, she says, these findings emphasize the importance of making sure pregnant women have support for mental health issues, which helps ensure current and future health for both mothers and babies.

“Mental health problems remain taboo, especially in the peripartum period where the expectation is that this is a wonderful time in a woman’s life. Many pregnant mothers aren’t getting the support they need,” Dr. Limperopoulos says. “Changes at the systems level will be necessary to chip away at this critical public health problem and make sure that both mothers and babies thrive in the short and long term.”

Other Children’s National researchers who contributed to this study include Dhineshvikram Krishnamurthy, M.S., software engineer; Li Zhao, Ph.D., research faculty; Kushal Kapse, M.S., staff engineer; Gilbert Vezina, M.D., neuroradiologist; Nickie Andescavage, M.D., neonatologist; Jessica Quistorff, M.P.H., clinical research program lead; and Catherine Lopez, M.S., clinical research program coordinator.

This study was funded by R01 HL116585-01 from the National Heart, Lung, and Blood Institute and U54HD090257 from the Intellectual and Developmental Disabilities Research Center.

First large-scale proteogenomic analysis offers insights into pediatric brain tumor biology

November 27, 2020

In the first large-scale, multicenter study of its kind, researchers conducted comprehensive analysis yielding a more complete understanding of pediatric brain tumors (PBT), which are the leading cause of cancer-related deaths in children. Researchers from the Clinical Proteomic Tumor Analysis Consortium (CPTAC) and Children’s Brian Tumor Network (CBTN) generated and analyzed proteomic data, which identifies common biological characteristics among different tumor types. The consortia consist of collaborators from the Icahn School of Medicine at Mount Sinai, National Cancer Institute, Fred Hutchinson Cancer Research Center, Children’s National Hospital and Children’s Hospital of Philadelphia. The study, published in Cell on November 25, 2020, provides a clearer understanding of the molecular basis of pediatric brain tumors and proposes new therapeutic avenues.

The molecular characterization of brain tumors has largely hinged upon the presence of unique alterations in the tumor genome ignoring the many layers of regulation that exist between DNA and the functional biology of the tumor cell that is actuated by proteins. The integration of proteomic data identifies common biological themes that span histologic boundaries, suggesting that treatments used for one histologic type may be applied effectively to other tumors sharing similar proteomic features.

Brian Rood, M.D., medical director of the Brain Tumor Institute and associate professor of pediatrics in the Center for Cancer and Blood Disorders at Children’s National Hospital, participated in this study and explains the importance of what the team discovered.

Q: Why was it important that researchers came together to do this work?

A: Comprehensive characterization of the fundamental biology of pediatric brain tumors, including the proteogenomic analysis done in this study, is essential to better understand and treat pediatric brain tumors.

Our study is based on the recognition that proteomics and phosphoproteomics needs to be integrated with other omics data to gain an improved systems biology view of the molecular features of brain tumors. In addition, characterizing biological themes that cross histologic boundaries and cells of origin can suggest extending treatments shown to be effective in one type of tumor to other histologically disparate tumors sharing the same proteomic features.

Proteomic data further reveal the functional impacts of somatic mutations and copy number variations (CNVs) not evident in transcriptomic data alone. Further, kinase-substrate network analyses identify activated biological mechanisms of tumor biology.

This work was only possible because of a unique collaboration between the CPTAC program of the NCI and the CBTN, of which Children’s National is a member.

Q: How will this work advance understanding and treatment of pediatric brain tumors?

A: Pediatric brain tumors have not benefitted from molecularly targeted drugs as much as other tumor types largely because they harbor relatively few gene mutations. Therefore, identifying key pathways to target in these patients’ tumors has been a challenge. The integration of proteomic and phosphoproteomic data with genomic data allows for the construction of a more comprehensive model of brain tumor biology and nominates specific key pathways to be targeted.

Q: What did you find that excites you?

A: Proteomic data revealed a number of findings that were not present in the genomic data. We found evidence to support a molecularly targeted approach to treating craniopharyngioma, a tumor that has previously been unresponsive to chemotherapy. We also found a prognostic marker for high grade gliomas that do not have a mutation in the H3 histone. We were able to identify specific kinases that may dictate the aggressive nature of certain ependymoma tumors. Importantly, we demonstrated the potential of proteomic studies to uncover unique tumor biology, paving the way for more extensive investigations using this approach.

Speckle tracking echo reveals possible biomarker for SUDEP risk

November 9, 2020

A study published in the journal Epilepsia used speckle tracking echocardiography to detect subtle changes in heart function found in pediatric patients with refractory epilepsy when compared to controls. Children with refractory epilepsy had impaired systolic ventricular strain compared to controls, not correlated to epilepsy history. These differences in ventricular function may be a biomarker that can indicate someone with epilepsy is at higher risk for Sudden Unexpected Death in Epilepsy (SUDEP).

Speckle tracking echocardiography is a non-invasive technique where software automatically identifies and tracks individual “speckles” of the myocardial wall on a routine echocardiogram in order to directly quantify the extent of contraction.

The study’s first authors, John Schreiber, M.D., medical director of Electroencephalography (EEG) and director of the Epilepsy Genetics program, and Lowell Frank, M.D., advanced imaging cardiologist and director of the Cardiology Fellowship Training program, both at Children’s National Hospital, answered some questions about the study findings.

Why is this important work?

Sudden unexpected death in epilepsy (SUDEP) is a rare but devastating consequence of epilepsy. Some of the proposed mechanisms of SUDEP implicate brain stem, cardiac and respiratory pathways.

This study identified alterations in ventricular function that may serve as one potential biomarker for SUDEP risk that can be evaluated non-invasively and regularly.

How will this work benefit patients?

Identification of children or adults with markedly impaired ventricular strain or diastolic function may provide the opportunity to implement a targeted treatment or monitoring strategy to prevent SUDEP.

What did you find that excites you? What are you hoping to discover?

These differences in cardiac strain were true for all patients with refractory epilepsy as a whole, not one particular group. This suggests that refractory convulsive epilepsy itself, rather than other patient-specific factors, produces these changes. Thanks in part to a grant from the Dravet Syndrome Foundation, the team is currently examining a cohort of patients with epilepsy due to pathogenic variants in sodium channel genes, SCN1A and SCN8A, to determine if these patients have greater degrees of impaired cardiac strain. SCN1A and SCN8A are also expressed in the heart, and patients have a considerably higher risk of SUDEP. It will be particularly exciting to examine for differences in specific genetic epilepsies.

How is this work unique?

Strain has been evaluated in many disease states in adult and pediatric populations and may be more sensitive to early myocardial damage than traditional measures of systolic and diastolic function. Children’s National Hospital has been an innovator in using speckle tracking echocardiography and similar techniques to evaluate subtle changes in heart function. This study is a great example of collaboration between The Comprehensive Pediatric Epilepsy Program and the Children’s National Heart Institute that is driving innovative research at Children’s National Hospital.

New research provides glimpse into landscape of the developing brain

November 6, 2020

Stem and progenitor cells exhibit diversity in early brain development that likely contributes to later neural complexity in the adult cerebral cortex, this according to a new study in Science Advances. This research expands on existing ideas about brain development, and could significantly impact the clinical care of neurodevelopmental diseases in the future.

Stem and progenitor cells exhibit diversity in early brain development that likely contributes to later neural complexity in the adult cerebral cortex, this according to a study published Nov. 6, 2020, in Science Advances. Researchers from the Center for Neuroscience Research (CNR) at Children’s National Hospital say this research expands on existing ideas about brain development, and could significantly impact the clinical care of neurodevelopmental diseases in the future. The study was done in collaboration with a research team at Yale University led by Nenad Sestan, M.D, Ph.D.

“Our study provides a new glimpse into the landscape of the developing brain. What we are seeing are new complex families of cells very early in development,” says Tarik Haydar, Ph.D., director of CNR at Children’s National, who led this study. “Understanding the role of these cells in forming the cerebral cortex is now possible in a way that wasn’t possible before.”

The cerebral cortex emerges early in development and is the seat of higher-order cognition, social behavior and motor control. While the rich neural diversity of the cerebral cortex and the brain in general is well-documented, how this variation arises is relatively poorly understood.

“We’ve shown in our previous work that neurons generated from different classes of cortical stem and progenitor cells have different functional properties,” says William Tyler, Ph.D., CNR research faculty member and co-first author of the study. “Part of the reason for doing this study was to go back and try to classify all the different progenitors that exist so that eventually we can figure out how each contributes to the diversity of neurons in the adult brain.”

Using a preclinical model, the researchers were able to identify numerous groups of cortical stem and precursor cells with distinct gene expression profiles. The team also found that these cells showed early signs of lineage diversification likely driven by transcriptional priming, a process by which a mother cell produces RNA for the sole purpose of passing it on to its daughter cells for later protein production.

“Our study provides a new glimpse into the landscape of the developing brain. What we are seeing are new complex families of cells very early in development,” says Tarik Haydar, Ph.D., director of CNR at Children’s National, who led this study. “Understanding the role of these cells in forming the cerebral cortex is now possible in a way that wasn’t possible before.”

Using novel trajectory reconstruction methods, the team observed distinct developmental streams linking precursor cell types to particular excitatory neurons. After comparing the dataset of the preclinical model to a human cell database, notable similarities were found, such as the surprising cross-species presence of basal radial glial cells (bRGCs), an important type of progenitor cell previously thought to be found mainly in the primate brain.

“At a very high level, the study is important because we are directly testing a fundamental theory of brain development,” says Zhen Li, Ph.D., CNR research postdoctoral fellow and co-first author of the study. The results add support to the protomap theory, which posits that early stem and progenitor diversity paves the way for later neuronal diversity and cortical complexity. Furthermore, the results also hold exciting translational potential.

“There is evidence showing that neurodevelopmental diseases affect different populations of the neural stem cells differently,” says Dr. Li. “If we can have a better understanding of the complexity of these neural stem cells there is huge implication of disease prevention and treatment in the future.”

“If we can understand how this early landscape is affected in disorders, we can predict the resulting changes to the cortical architecture and then very narrowly define ways that groups of cells behave in these disorders,” adds Dr. Haydar. “If we can understand how the cortex normally achieves its complex architecture, then we have key entry points into improving the clinical course of a given disorder and improving quality of life.”

Future topics the researchers hope to study include the effects of developmental changes on brain function, the origin and operational importance of bRGCs, and the activity, connections and cognitive features enabled by different families of neurons.

The campus, now under construction, is being developed on nearly 12 acres of the former Walter Reed Army Medical Center. Children’s National will name the main auditorium in recognition of Boeing’s generosity.

“We are deeply grateful to Boeing for their support and commitment to improving the health and well-being of children in our community and around the globe,” said Kurt Newman, M.D., president and CEO of Children’s National “The Boeing Auditorium will help the Children’s National Research & Innovation campus become the destination for discussion about how to best address the next big healthcare challenges facing children and families.”

The one-of-a-kind pediatric hub will bring together public and private partners for unprecedented collaborations. It will accelerate the translation of breakthroughs into new treatments and technologies to benefit kids everywhere.

“Children’s National Hospital’s enduring mission of positively impacting the lives of our youngest community members is especially important today,” said Boeing President and CEO David Calhoun. “We’re honored to join other national and community partners to advance this work through the establishment of their Research & Innovation Campus.”

Children’s National Research & Innovation Campus partners currently include Johnson & Johnson Innovation – JLABS, Virginia Tech, the National Institutes of Health (NIH), Food & Drug Administration (FDA), U.S. Biomedical Advanced Research and Development Authority (BARDA), Cerner, Amazon Web Services, Microsoft, National Organization of Rare Diseases (NORD) and local government.

The 3,200 square-foot Boeing Auditorium will be the focal point of the state-of-the-art conference center on campus. Nationally renowned experts will convene with scientists, medical leaders and diplomats from around the world to foster collaborations that spur progress and disseminate findings.

Boeing’s $5 million commitment deepens its longstanding partnership with Children’s National. The company has donated nearly $2 million to support pediatric care and research at Children’s National through Chance for Life and the hospital’s annual Children’s Ball. During the coronavirus pandemic, Boeing fabricated and donated 2,000 face shields to help keep patients and frontline care providers at Children’s National safe.

Madison Berl, Ph.D., receives 2020 PERF award for Infrastructure/Registry Research

November 4, 2020

The Pediatric Epilepsy Research Foundation Grant (PERF) has awarded Madison Berl, Ph.D., neuropsychologist at Children’s National Hospital, the 2020 PERF award for Infrastructure/Registry Research. The funds will support her work on researching neuropsychological outcomes of children being considered for pediatric epilepsy surgery.

This grant, which provides $200,000 of research funding, will allow Dr. Berl to systematically collect data outcomes and create robust prediction models that are critical to achieving precision medicine that allows for selecting the most effective surgical treatment for an individual child.

“While seizures are a critical outcome, there is increasing recognition that outcomes beyond seizure control is critical to children and their families when evaluating and treating the impact of epilepsy and its treatments,” said Dr. Berl.

Guidelines and consensus statements related to pediatric epilepsy surgery are uniformly lacking high quality published outcome data to support clinical decisions that impact likelihood of seizure freedom and optimizing outcomes beyond seizures (e.g., neuropsychological functioning, quality of life, improved sleep). Despite recognition of the need for standardized collection of data on a multi-institutional basis, the efforts that exist are limited in scope.

Moreover, as new techniques – such as laser ablation and brain stimulation – are approved for pediatric patients, there is little information available to determine which children will benefit from which intervention.

“This project fundamentally is a multi-site registry for epilepsy surgery outcomes,” Dr. Berl added.

“However, this type of infrastructure also fosters growth and active collaboration within a network of pediatric epilepsy clinicians. I am excited because if successful, this will be the start of long-term collaborative effort.”

Thrombectomy can be efficient and safe in childhood stroke, new study finds

October 28, 2020

A recent study adds to the growing evidence that mechanical thrombectomy can be effective and safe not only in adults, but also in childhood stroke.

Previous randomized trials proved the effectiveness of thrombectomy for large intracranial vessel occlusions in adults only. However, a recent retrospective study led by Monica S. Pearl, M.D., Neurointerventional Radiology Program director at Children’s National Hospital, finds that thrombectomy can be safely performed in carefully selected cases of childhood stroke. The study further shows that treated children have good neurological outcomes.

In the findings, Dr. Pearl and other leading experts discussed specific circumstances and important considerations to take into account when managing a child with acute ischemic stroke due to a large vessel occlusion.

“We are raising the bar for the expected level of care for children with acute ischemic stroke,” said Dr. Pearl. “Care should be multidisciplinary and involve stroke neurology, neuroradiology, neurointerventional radiology, neurosurgery, cardiology, hematology and ICU teams.”

Prior to the study, clear guidelines for patient selection, thrombectomy technique and periprocedural care did not exist for the pediatric population despite the proven success of mechanical thrombectomy in adults.

Through a case-based approach encompassing a broad range of ages and clinical presentations, Dr. Pearl and other leading experts presented select cases of acute ischemic stroke in children and discussed the nuances, risks, benefits and management plan for each child.

Many of the clinical scenarios highlighted unanswered questions in the management and treatment of children with acute ischemic stroke due to large vessel occlusion. The study adds to the growing evidence that mechanical thrombectomy can be effective and safe not only in adults, but also in childhood stroke.

“It’s exciting to be shaping management for children with acute ischemic stroke,” said Dr. Pearl. “We are serving as the model for individualized, patient-centered care with multidisciplinary specialists and institutional collaboration caring for children with acute ischemic stroke.”

However, Dr. Pearl and experts encourage caution because etiology in childhood stroke differs substantially from that in acute ischemic stroke in adults, with potentially major impact on procedure success and safety.

The mission of the Neurointerventional Radiology Program, a new effort at Children’s National, is to provide exceptional family-centered care and cutting-edge diagnostic and endovascular treatment options for children with neurovascular disorders. Dr. Pearl serves as the program’s full time, dedicated neurointerventional radiologist, a specialized expertise found only in a handful of other pediatric hospitals in the country.

NIH grant supports research on locomotor dysfunction in Down Syndrome

October 15, 2020

The National Institutes of Health (NIH) has granted the Children’s National Research Institute (CNRI) nearly $500,000 to better understand and identify specific alterations in the circuitry of the cerebellum that results in locomotor dysfunction in down syndrome.

Down syndrome (DS), the most commonly diagnosed chromosomal condition, affects a range of behavioral domains in children including motor and cognitive function. Cerebellar pathology has been consistently observed in DS, and is thought to contribute to dysfunction in locomotor and adaptive motor skills. However, the specific neural pathways underlying locomotor learning that are disrupted in DS remain poorly understood.

The National Institutes of Health (NIH) has granted the Children’s National Research Institute (CNRI) nearly $500,000 through their NIH-wide initiative INCLUDE – INvestigating Co-occurring conditions across the Lifespan to Understand Down syndrome – to better understand and identify specific alterations in the circuitry of the cerebellum that results in locomotor dysfunction in DS. The INCLUDE initiative aims to support the most promising high risk-high reward basic science.

“There is still a lot unknown about Down syndrome, in particular how fundamental cellular and physiological mechanisms of neural circuit function are altered in this syndrome,” says Vittorio Gallo, Ph.D., chief research officer at Children’s National Hospital and scientific director of CNRI. “Grant funding is particularly important to have the resources to develop and apply new cutting-edge methodology to study this neurodevelopmental disorder.”

The main goal of this research is to identify specific alterations in the circuitry of the cerebellum that result in locomotor dysfunction in DS. Defining specific abnormalities in motor behavior, and identifying the brain regions and neurons which are functionally involved will provide the basis for developing potential therapies for treating motor problems in individuals with DS.

“The last decade has brought rapid advances in neurotechnology to address questions at the ‘systems-level’ understanding of brain function,” says Aaron Sathyanesan, Ph.D., a Children’s National postdoctoral research fellow. “This technology has rarely been applied to preclinical models of neurodevelopmental disorders, and even more rarely to models of Down syndrome.”

An example is the use of fiber-optics to probe changes in neural circuitry during behavior. Using this technology, researchers can now directly correlate the changes in circuitry to deficits in behavior.

“Along with the other approaches in our proposal, this represents the synthesis of a new experimental paradigm that we hope will push the field forward,” says Dr. Sathyanesan.

In 1960, the average life expectancy of a baby with Down syndrome was around 10 years. Today, that life expectancy has increased to more than 47 years. That significant increase reflects critical advances in medicine, however, kids with DS still live with long-term challenges in motor and cognitive ability.

Children’s National strongly supports translation and innovation, and recently recruited internationally renowned DS researcher, Tarik Haydar, Ph.D., as its new director of the Center for Neuroscience Research.

“We’re building significant strength in this area of research. This grant helps open new avenues of investigation to define which cells and circuits are impacted by this common neurodevelopmental disorder,” says Dr. Gallo. “Our cutting-edge approach will help us answer questions that we could not answer before.”

Children use both brain hemispheres to understand language

September 11, 2020

New research finds young children process language in both hemispheres of the brain, which could help compensation after a neural injury. This is unlike adults who process most language tasks in one side (usually the left) of their brain’s two hemispheres. It suggests a possible reason why children often seem to recover from brain injury more easily than adults.

New research finds young children process language in both hemispheres of the brain, which could help compensate after a neural injury. The study, published Sept. 8, 2020, in PNAS, says this is unlike adults who process most language tasks in one side (usually the left) of their brain’s two hemispheres. It suggests a possible reason why children often seem to recover from brain injury more easily than adults.

We talked with researcher William D. Gaillard, M.D., chief of the Divisions of Child Neurology, Epilepsy and Neurophysiology at Children’s National Hospital, to discuss the importance of this work.

Q: Tell us a little bit about this study.

A: This is a study we did with our colleagues at Georgetown University Medical Center, using fMRI to map brain regions that are used to process language across development. What we found was that younger children have more bilateral “activation” in language processing regions, the traditional left and homotopic regions in the right. With aging there is consolidation that becomes more left lateralized. This process is most clearly seen in the frontal brain regions, called Broca’s area, where the right activation diminishes over age

Q: Why are these findings important?

A: It’s important because this work provides evidence for how cognitive systems, and the neural networks that underlie them, become consolidated and lateralized over time during development. It provides insights into principles of the development of cognitive systems.

The timeline for lateralization of language systems means that the cognitive systems that sustain language are “plastic” – that is the right hemisphere can sustain language functions in the setting of injury to the left hemisphere until around 10 years of age.

Q: What excites you about this work?

A: This is part of a larger collaborative effort that is mapping out the consolidation of cognitive systems across development (language, visual spatial, memory and working memory). This work will help us to understand the limits of brain plasticity in the setting of injury caused by stroke or epilepsy, which could have benefits down the road to helping patients recover from these types of events.

Q: How is Children’s National leading the ongoing discovery in this space?

A: It is a true team effort. We are working with colleagues at Georgetown University Medical Center, MedStar National Rehabilitation Network and Johns Hopkins Medicine. Team members come from diverse backgrounds and scientific skills. We are one of the leading groups using advanced functional imaging to investigate brain development of critical cognitive systems and their response to brain injury.

Research reveals physiological sex differences in medial amygdala neurons

September 10, 2020

The medial amygdala (MeA) is a region of the brain that modulates innate social and non-social behaviors in several mammals, including humans.

The medial amygdala (MeA) is a region of the brain that modulates innate social and non-social behaviors in several mammals, including humans. Notedly sexually dimorphic, MeA neurons exhibit well-documented sex differences in anatomy, morphology and molecular characteristics. Recently, a pioneer study published in eNeuro from the Children’s National Hospital Center for Neuroscience Research has unveiled new information regarding physiological sex differences in MeA neurons, which, until now, has remained a missing piece in understanding how the MeA codes differently in males and females.

Previous research from Children’s National has shown that two subpopulations of MeA inhibitory output neurons descended from Dbx1 and Foxp2 transcription factors display different responses to innate olfactory cues and in a sex-specific manner. The newest study examines whether these transcription factor defined neurons also possess sex-specific biophysical signatures. The scientists posit that understanding how sex and lineage impact upstream differences at the neuronal level can help illuminate how the MeA processes information and codes for sex-specific behavioral differences.

Using whole-cell patch clamp recording and stepwise current injection, the researchers were able to analyze the intrinsic electrophysiological profiles of the two subclasses of MeA neurons in males and females in a pre-clinical model. Data revealed that the spike frequency of Dbx1-lineage and Foxp2-lineage neurons differed by lineage, sex and stimulus strength. Dbx1-lineage neurons in females discharged more spikes than those in males during high-amplitude current injection, while Foxp2-lineage neurons in females discharged more spikes than those in males during low-amplitude current injection. Across lineage, researchers observed that Dbx1-lineage neurons discharged more spikes than Foxp2-lineage neurons in females, but only at the highest amplitude stimulus, while Dbx1-lineage neurons spiked more than Foxp2-lineage neurons in males during low rather than high-amplitude current injection.

Different spiking patterns are generally indicative of different intrinsic cell properties. However, this study found that the intrinsic properties of the cell – such as membrane potential, resistance, and rheobase – were the same at rest across sex and lineage. The only significant difference was found in capacitance, an electrical measurement that roughly corresponds with cell size. Additionally, the study found that spike frequency adaptation correlated with neuronal lineage and sex, with males having a higher adaptation factor than females and Foxp2-lineage neurons displaying a higher adaptation factor than Dbx1-lineage neurons. In tandem, these results indicated that changes in the intrinsic properties were taking place during stimulation.

The researchers then used waveform phase-plots to visualize phases of the different action potentials and contrived an innovative new method of analyzing these quantitatively instead of solely qualitatively. This allowed them to know that broadly, ion channels that work with repolarization are likely different, and prompted them to focus on the family of ion channels that are known to modify the repolarization phase. From 62 candidate ion channels, the researchers chose 10 to investigate. Experiments ultimately revealed that only one ion channel was found to exhibit statistically significant sex differences in the Foxp2 population. This result indicated that molecular expression of these ion channels are likely driving differences in the physiology of the cells which may be the basis of behavioral expression. Future research topics include how and when sex hormones shape MeA neuronal firing properties and how this relates to network function.

“This is a small piece of contribution to the overall understanding of how the brain as a biological machine codes for different outputs,” says first author Heidi Y. Matos, Ph.D.

By showing sex differences in neural function, this research represents progress in understanding the biological underpinnings of a host of developmental disorders, particularly those diagnosed in different proportions between males and females. Autism spectrum disorders, for example, often have symptoms that manifest through social interaction, and understanding these disorders requires a better understanding of normal MeA physiology.

“In order to get to the why, we have to get to the how of that circuit,” says Dr. Matos.

Just as the brain harnesses the collective power of a diverse range of neurons, the Center for Neuroscience harnesses the aggregate talent of a diverse group of neuroscientists to produce innovative work. This study in particular champions diversity in the sciences, with more than half of the authors coming from underrepresented minorities, including Dr. Matos.

“I think this work is a shining example of the tremendous contributions that are made by neuroscientists from all backgrounds,” says principal investigator Joshua G. Corbin, Ph.D.

“Sex Differences in Biophysical Signatures across Molecularly Defined Medial Amygdala Neuronal Subpopulations” was published in eNeuro. Additional authors include David Hernandez-Pineda, Claire M. Charpentier, Allison Rusk and Kevin S. Jones, Ph.D.

Dr. Youssef Kousa awarded Pediatric Epilepsy Research Grant

August 31, 2020

The Child Neurology Foundation has awarded Youssef A. Kousa, M.S., D.O., Ph.D., the 2020 Pediatric Epilepsy Research Foundation Shields Research Grant. The funds will support his work on identifying genetic risk factors in congenital Zika syndrome.

The Child Neurology Foundation has awarded Youssef A. Kousa, M.S., D.O., Ph.D., physician-scientist within the Division of Neurology at Children’s National Hospital, and founder and director of the Zika Genetics Consortium, the 2020 Pediatric Epilepsy Research Foundation Shields Research Grant. The funds will support his work on identifying genetic risk factors in congenital Zika syndrome.

This prestigious grant provides $100,000 of research funding to help identify treatments and cures for pediatric neurologic diseases. It will allow Dr. Kousa to test the hypothesis that rare genetic variants in individuals contributed to being affected with congenital Zika syndrome and the severity of the phenotype for those who were affected.

“Despite decades of research, identifying those at greatest risk of congenital infection or being severely affected remains an elusive goal,” says Dr. Kousa. “This research is important because identifying genetic risk or protective factors for developmental brain malformations can help teach us how the brain develops.”

In 2015, Dr. Kousa established the Zika Genetic Consortium to investigate whether maternal and fetal genetic factors can modify the risk of brain injury from congenital infections.

Dr. Kousa adds that this work will provide key insights into maternal and fetal genetic factors that can contribute to brain malformations. The hope is that these insights may one day translate into targeted prevention efforts.

“Dr. Kousa’s project is very creative and has a fantastic opportunity to look at factors of Zika on brain development,” says William D. Gaillard, M.D., division chief of both Epilepsy and Neurophysiology, and Neurology at Children’s National. “This is a very competitive award. It’s a tremendous achievement that few accomplish.”

Children’s National is the leading site for this international research study.

In 2015, Dr. Kousa established the Zika Genetic Consortium to investigate whether maternal and fetal genetic factors can modify the risk of brain injury from congenital infections. Dr. Kousa is the principal investigator of the consortium, which includes 19 co-investigators representing 13 different institutions.

The consortium is bringing together cohorts of 12,000 mother-infant participants retrospectively and prospectively. These cohorts come from 15 international health centers in seven countries in collaboration with partners at the National Institutes of Health, and the Centers for Disease Control and Prevention.

“This support gives us the opportunity to test our hypothesis,” says Dr. Kousa. “We also hope what we continue to learn about Zika can play a role in helping us understand other congenital infections and neurodevelopment diseases.”

Children’s National designated CMTA Center of Excellence

August 6, 2020

Charcot-Marie-Tooth (CMT) is a degenerative nerve disease that frequently appears in adolescents and early adulthood but can also be seen with onset in early childhood.

Children’s National Hospital is proud to receive the designation as a CMTA Center of Excellence. One of the CMTA’s primary missions is improving the quality of life for those with Charcot-Marie-Tooth (CMT), a degenerative nerve disease that while frequently appears in adolescents and early adulthood, can also be seen with onset in early childhood. Through these 35 CMTA Centers of Excellence, children, adults and families affected by CMT can be assured of receiving comprehensive care by a team of CMT experts that will now be available at Children’s National.

“It’s an honor for Children’s National and our multidisciplinary team to be recognized as a CMTA Care Center,” says Diana Bharucha-Goebel, M.D., neuromuscular neurologist and neurophysiologist at Children’s National. “Our team has long strived to provide comprehensive and specialized care for children with CMT, ranging from expertise in genetic and electrophysiologic diagnostics to specialized family centered care in orthopedics, physical and occupational therapies, physical medicine and rehabilitation, neurology, nutrition and bone health.”

This is the first time Children’s National has received the CMTA Center of Excellence designation. Doctors at Children’s National applied for this designation directly through the CMTA and were selected based on recognition of its program services, patient volume, expertise and experience.

Approximately 20 of the CMTA Centers of Excellence are INC-designated centers, a group of academic medical centers, patient support organizations and clinical research resources sponsored in part by the CMTA. The CMTA Centers of Excellence will become even more important as the CMTA begins clinical trials for candidate therapies.

The success of these trials will largely depend on how much information is available about the natural history of CMT. Specifically, how different types of CMT progress over time and whether novel medications are slowing the course of the disease. Much of that information will be provided by the Centers of Excellence.

“We are excited for the ongoing opportunities as a CMTA Care Center, especially at a time when novel therapeutic strategies are emerging in the field of neuromuscular medicine,” said Dr. Bharucha-Goebel.
