Splet02. feb. 2024 · Since the discovery of human leukocyte antigens (HLAs), the function of major histocompatibility complex (MHC) gene families in a wide range of diseases have been the subject of research for decades. In particular, the associations of autoimmune disorders to allelic variants and candidate genes encoding the MHC are well documented. SpletAbstract Major histocompatibility complex (MHC) class I genes encode highly polymorphic molecules that are expressed on virtually every cell type, and have been identified in all but the most primitive vertebrates. They play a number of crucial roles in the immune response to infectious disease.
Splet11. nov. 2013 · The TCR binds to cognate peptide-loaded MHC (pMHC) by the TCR α and β chains, forms the immunological synapse by clustering accessory components including CD3ζ and CD28, and initiates the downstream signaling pathway for T-cell activation through phosphorylation of the CD3ζ ITAM motives.
