Michael Hsieh, M.D., hopes to use parasite proteins to alleviate pain in multiple types of bladder inflammation.

Children’s National Health System Urologist Michael Hsieh, M.D., was awarded a National Institutes of Health (NIH) grant to optimize a set of parasite proteins that could alleviate pain in multiple types of bladder inflammation.

The $1 million R01 grant will fund a five-year study to exploit a parasite-derived protein, IPSE, as a candidate therapeutic. Dr. Hsieh hypothesizes that IPSE may have the ability to modulate host immune and non-immune responses to bladder injury. IPSE could be optimized for therapeutic potential, while minimizing toxicity, by generating forms that have the ability to modulate host responses via three distinct mechanisms: IL-4-binding, chemokine-binding and nuclear localization.
