Major histocompatibility (MHC) molecules enable T lymphocytes to recognize epitopes of antigens and discriminate self from nonself. Unlike B-cell receptors on B lymphocytes that are able to directly bind epitopes on antigens, the T-cell receptors (TCRs) of T lymphocytes can only recognize epitop... Read More
