| Gene and Protein Information Comments | ||||||
| Two mouse homologs for human CD1d have been identified, Cd1d1 (MGI:107674) and Cd1d2 (MGI:107675). These two mouse isoforms present different sets of self-antigen(s) in the mouse thymus, and thus have an impact on iNKT cell development in the mouse [11]. The 336 aa isoform 1 from mouse Cd1d2 encodes a functional protein in 129, NMRI, AKR/J, and other mouse strains, but not in C57BL/6 mice. | ||||||

| Immunopharmacology Comments |
| CD1d is a lipid-binding MHC class I-like protein that is expressed by dendritic cells. CD1d presents self and microbial lipid/glycolipid antigens to unconventional T cells known as invariant natural killer T (iNKT) cells [2,13]. The iNKT cells are activated by interaction of the CD1d-glycolipid complex with the T cell receptor and an immune response is initiated. Synthetic glycolipid-like ligands that bind CD1d have been developed as immunomodulators and there has been some investigation of these as anti-cancer immunotherapy [1,5,7,13] (e.g. KRN7000 [4,6,10], although this agent has shown limited clinical efficacy for various reasons[8,14]). Activation of iNKT cells via CD1d may also be applicable for the treatment of autoimmune diseases [9,12]. |
