WebThe class III region of the HLA complex is located between the class I and class II regions. Whereas HLA class I and class II genes encode sets of structurally related, highly polymorphic transplantation antigens, the class III region consists of at least four types of genes, only two of which have obvious functions in the immune system.

Unlike other MHC types such as MHC class I and MHC class II, of which their structure and functions in immune response are well defined, MHC class III are poorly defined structurally and functionally. They are not involved in antigen binding (the process called antigen presentation, a classic function of MHC proteins). Only few of them are actually involved in immunity while man…

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. From: Encyclopedia of Immunobiology, 2016.
