Quizplus · Accepted Answer

T cell receptors (TCRs) are able to recognize antigens presented on major histocompatibility complex (MHC) molecules. MHC molecules are present on all cells in the body and are used to present self-antigens to T cells during development, allowing for the selection of T cells that are able to discriminate self from nonself. Therefore, TCRs are able to discriminate between self (antigens presented on self MHC) and nonself (antigens presented on nonself MHC).
