Question

Quizplus · Accepted Answer

When tissues are transplanted, the MHC (major histocompatibility complex) molecules on the surface of the cells play a critical role in determining compatibility with the recipient's immune system. If the MHC molecules are not a close enough match, the recipient's immune system will recognize the transplanted tissue as foreign and mount a rejection response. Therefore, matching MHC molecules is crucial for successful tissue transplantation. The other options listed (perforins and interleukins) are involved in immune responses but are not directly related to preventing rejection in tissue transplants.
