HMS has a core expertise in immunobiology, with investigators in several departments studying regulation of immune cell function, trafficking, and signaling. Recent findings include the paradigm-shifting demonstration by Ulrich Von Andrian’s laboratory that circulating hematopoietic stem and progenitor cells infiltrate peripheral organs and provide a localized response to infection and inflammation. In the area of T cell biology, Arlene Sharpe’s studies on co-stimulatory molecules such as PD-1 have shed new light on the intricacies of the immune response in responding to persistent viral infections.
