Question

Quizplus · Accepted Answer

Tissue rejection from transplants is caused by the mismatch of HLA antigens between the donor and the recipient. This triggers an immune response in which cytotoxic T cells attack the transplant. Both statements are correct. Memory B cells may also be involved in the immune response, but they are not the main cause of tissue rejection.
