El complejo mayor de histocompatibilidad

The major histocompatibility complex (MHC) is a family of genes found in all vertebrates and located on the short arm of chromosome 6 in humans. Its function is to encode molecules (glycoproteins) called human leukocyte antigens (HLAs), which are involved in the presentation of antigens to T lymphocytes, enabling the activation of critical processes in the generation of the immune response. In general, the MHC distinguishes between self and nonself.
