BIO 4629 Scientific Inquiry


Whether just a cut, or life-threatening pneumonia, we have all experienced the effects of inflammation. Accumulating evidence suggests that the small anucleate cells called platelets regulate both the intensity and outcomes of many of the body’s inflammatory responses. Dr. Washington’s laboratory studies a platelet receptor called TLT-1 (the Triggering Receptor Expressed in Myeloid cells (TREM) Like Transcript -1) that seems to function at the interface of hemostasis, mediated by platelets, and inflammation directed by the immune system. His laboratory uses basic biochemistry, animal models, and human subjects to unravel novel mechanisms by which platelets interaction with the immune system direct disease outcomes.
