Skin transplants often face rejection by the immune system, but research shows skin grafts may be pre-treated with dendritic cells before the transplant to prevent organ rejection.
In 2016, more than 33,000 organ transplants occurred in the U.S. After a person receives a transplant, the immune system may attack the organ as foreign. This can occur rapidly, within the first year, in about 15% of people who receive kidney transplants, for example. However, skin transplants are rejected at a much higher rate for reasons that are not fully understood. Researchers of Brigham and Women's Hospital embarked on research studies to determine the cause of skin transplant rejection by the immune system and how this can be prevented.
