The MHC determines the compatibility of donors for an organ transplant, as well as susceptibility to autoimmune disease. The prime histocompatibility complex is a set of cell surface for recognition by the suitable T-cells. MHC molecules liaise interactions of leukocytes, which are also called white blood cells, which are immune cells.
The primary function of MHC molecules is to unite to antigens acquired from pathogens and present them on the surface of the cell for recognition by the appropriate T-cells. MHC is the tissue antigen that allows the immune system to bind to (T cells).
The diversity of antigen presentation mediated MHC classes. MHC molecules chaperone which type of lymphocytes may bind to the given antigen with high affinity, since different lymphocytes express different T-cell receptors.
