WebPubMed WebHuman Leukocyte Antigen. Human leukocyte antigens (HLA) are encoded by a highly polymorphic set of genes and are expressed as cell surface receptors that present antigenic peptides to T cells in a restricted manner, which allows discrimination between self- and foreign antigens.

WebMHC Class I presentation is from any nucleated cell to a CD8+ cell (cytotoxic T cells). MHC Class II presents to CD4+ (helper T cells).
