Mechanism Behind Organ Transplant Rejection

UCLA researchers have pinpointed the culprit behind chronic rejection of heart, lung and kidney transplants. Published in the Nov. 23 edition of Science Signaling, their findings suggest new therapeutic approaches for preventing transplant rejection and sabotaging cancer growth.
The team focused on the mechanism behind narrowing of the donor’s grafted blood vessels, which blocks blood from reaching the transplanted organ. Starved of oxygen and other nutrients, the organ eventually fails, forcing the patient back on the transplant waiting list.
