The Tang Lab is working on several projects relating to the role of regulatory T cells (Tregs) in suppressing the immune system in order to develop therapeutic protocols for transplant rejection and autoimmune disease.  In addition, several researchers work with transplanted islets to evaluate both the immune response post-transplant and the contribution of immunosuppressive drugs to islet graft loss.  Dr. Tang is also a co-investigator alongside Drs. Peter Stock, MD, PhD and Flavio Vincenti, MD on a project involving immune monitoring of HIV+ transplant recipients.
