  • Induction of transplantation tolerance to block alloimmunity and recurrent autoimmunity following pancreatic islet transplantation
  • Safety and efficacy of solid organ transplantation in people with HIV


Peter G. Stock, M.D., Ph.D. is Professor of Surgery at UCSF, Surgical Director of the Pediatric Renal Transplantation Program and Surgical Director of the Pancreas Transplant Program. He was trained at the University of Minnesota, completing a surgical residency before coming to UCSF for a transplant fellowship. He joined the UCSF faculty in 1992.  

Recently, a clincial investigation on which Dr. Stock served as principal investigator led the passage of the Hope Act lifting the ban on research for transplanting organs between HIV-positive donors and recipients.

Highly respected by his peers, Dr. Stock was named to the list of U.S. News "Top Doctors," which denotes the top 10% of physicians within a region practicing a given specialty. He is a frequent presenter on issues related to transplantation and immunosuppression, and holds membership in numerous professional and honorary societies. Dr. Stock specializes in liver, kidney and pancreas transplantation.

Research Overview

Pancreatic Islet Transplantation
The translational research in the field of pancreatic islets revolves around clinical trials of the safety and efficacy of islet transplantation in patients with Type I diabetes. The clinical trials are funded by the National Institutes of Health (NIH) and the Juvenile Diabetes Research Foundation (JDRF). These clinical trials focus on novel immunosuppressive strategies that utilize co-stimulatory blockade to prevent the immune response against pancreatic islets with a regimen that is not toxic to kidneys or beta cells.

Related research involves improving the techniques required for isolating pancreatic islets from the pancreas, which is being conducted in a fully compliant GMP laboratory facility. The study of the alloimmune and autoimmune response following islet transplantation will be conducted to determine the efficacy of the immunosuppressive strategies. Further translational studies will include methods of expanding the source of beta cells, using direct proliferation, as well as manipulation of precursor cells localized in the adult pancreas. We are currently funded (PI) for a translational grant from California Institute of Regenerative Medicine (CIRM) to bring embryonic stem cell-derived beta cells to a clinical trial.

Solid Organ Transplantation in People with HIV
With the advent of highly active anti-retroviral therapy (HAART), HIV has been a chronic disease. People with HIV are no longer dying from progression of HIV to AIDS, but rather as a result of end stage live disease (viral hepatitis co-infection) and kidney disease (HIV nephropathy). Our laboratory heads up the large NIH-sponsored national multicenter trial which is studying the safety and efficacy of solid organ transplantation in people with HIV. Translational research is exploring the impact of HIV on organ function and the impact of immunosuppression on the immune response against HIV and associated copathogens.
