Abstract:
CD1d molecules are lipid antigen-presenting molecules. They are involved in presenting these antigens to a unique subpopulation of T cells called natural killer T (NKT) cells, which have the capacity to produce both T helper (Th) 1 and Th2 cytokines. Thus, it is possible that the antigens presented by CD1d and/or the level at which they are presented could have profound effects on the immunoregulation of autoimmune and infectious diseases, as well as cancer. Because of the ability of CD1d-binding ligands to modulate NKT cell responses, targeting CD1d-mediated antigen presentation as a novel approach for new therapies in these and other diseases holds great promise.
