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. WebMay 23, 2024 · The class II MHC genes encode glycoproteins expressed primarily on antigen-presenting cells (macrophages, dendritic cells, and B cells), where they present processed antigenic peptides to TH cells. The class II proteins are encoded by the HLA-D region and the HLA-D regions have three families, DP-, DQ-, and DR-encoded molecules.
