Description

Mouse Monoclonal Antibody

The MAb 51.1 reacts with human CD1d, a member of the CD1 family with similarity to the non-polymorphic MHC Class I-like molecules. CD1d is a highly conserved single transmembrane receptor of the Immunoglobulin Superfamily. CD1d can associate with beta-microglobulin another feature showing similarity to MHC class I molecules, but can also exist as a nonglycosylated protein not in association with beta microglobulin. This suggests different control mechanisms for presenting glycolipid containing molecules to CD1d reactive NKT cells. Expression of CD1d is found on B cells of the periphery, in resting monocytes and cortical thymocytes. On intestinal epithelial cells (IEC) expression is polarized. Expression can also be found at low levels intracellularly in hepatocytes. In HCV (hepatitis C virus) livers, CD1d is highly expressed compared to normal controls. The 51.1 MAb has been shown to have functional activity; blocking the interaction of CD1d transfected cells with NKT cells.

CD1d is a heavy chain associated with Beta 2 microglobulin on cortical thymocytes. Beta 2 microglobulin independent expression of CD1d has also been demonstrated on human intestinal epithelial cells. CD1d is the sole group 2 member of the CD1 family of major histocompatibility (MHC) like glycoproteins. The CD1d gene encodes a divergent member of the CD1 family of transmembrane glycoproteins, which are structurally related to the major histocompatibility complex (MHC) proteins and form heterodimers with beta-2-microglobulin. The CD1 proteins mediate the presentation of primarily lipid and glycolipid antigens of self or microbial origin to T cells. The human genome contains five CD1 family genes organized in a cluster on chromosome 1. The CD1 family members are thought to differ in their cellular localization and specificity for particular lipid ligands. The protein encoded by the CD1d gene localizes to late endosomes and lysosomes via a tyrosine-based motif in the cytoplasmic tail. Diseases associated with CD1D include Mycobacterium Malmoense and Autoimmune Disease.
