Research interests
While also conducting transplant immunotherapy research for liver and kidney whole organ transplants and allografts, the main focus of Dr. Gaber´s research is in the transplantation of islets to alleviate diabetic complications. He and his collaborators have developed the protocol for long term islet culture and described the clinical transplantation of islets through the intestinal veins. Dr. Gaber´s current studies center on the testing of gene therapy and other approaches to test for islet viability and assist the transplanted islets to develop a sustaining blood supply and resist rejection by the recipient's immune system.
