Question

Quizplus · Accepted Answer

A transplant of an improperly matched organ can cause rejection by the body's immune system due to the presence of non-self proteins in the tissue, the presence of foreign MHC proteins on the donor tissue, and the immune response of antibodies and cytotoxic T lymphocytes (CTLs) to foreign tissue. Both non-self proteins in the tissue and antibodies and cytotoxic T lymphocytes (CTLs) responding to foreign tissue can cause an organ to be rejected.
