HLA human leukocyte antigen refers to a gene complex encoding the major histocompatibility complex MHC proteins in humans while MHC refers to a set of cell surface proteins essential for the acquired immune system to recognize foreign molecules in vertebrates, which in turn determines histocompatibility.

However, MHC is a gene complex, which expresses surface antigens on all nucleated cells in vertebrates. The main function of MHC molecules to present antigens to the T cells. It allows the T cell recognition of foreign antigens upon self-antigens. Williams, T M. Available Here 2. Learn how your comment data is processed. Forgot your password? Lost your password?
