Biography

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. Dr. Stock specializes in liver, kidney and pancreas transplantation.

For many years, Dr. Stock was Chair of the Department of Surgery Research Committee. Under his  outstanding leadership. he has helped to establish UCSF Surgery as one of the top research programs for surgical residents in the U.S.

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.

Dr. Stock is a frequent presenter on issues related to transplantation and immunosuppression, and holds membership in numerous professional and honorary societies.

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.

    "People infected with the AIDS virus can safely receive a kidney transplant, researchers reported on Wednesday. The finding, published in Thursday's New England Journal of Medicine, is good news for people with HIV who are more prone to kidney disease, in part because of the drugs they must take to stay healthy. Before drug cocktails turned HIV from a death sentence to a chronic condition, patients were not eligible to receive a kidney. But now they can. 'Patient and graft survival are really [...]
