The most important feature to recognize during organ transplant is the difference between the MHC proteins of the donor and the recipient. MHC proteins play a critical role in the compatibility of transplanted tissues and organs, as they are responsible for presenting antigens to the immune system. If the donor and recipient have different MHC proteins, the recipient's immune system may recognize the transplanted organ as foreign and mount an attack, leading to organ rejection. Therefore, matching MHC proteins between donor and recipient is essential for a successful transplant.
