"CD1 (cluster of differentiation 1) is a family of glycoproteins expressed on the surface of various human antigen-presenting cells. CD1 glycoproteins are structurally related to the class I MHC molecules, however, in contrast to MHC class 1 proteins, they present lipids, glycolipids and small molecules antigens to T cells. Both αβ and γδ T cells recognise CD1 molecules. The human CD1 gene cluster is located on chromosome 1. Genes of the CD1 family were first cl… " - Cd1 tcr
