Definition / General
  • CD1d presents lipid antigens to natural killer T (NKT) cells; when activated, NKT cells rapidly produce Th1 and Th2 cytokines, typically represented by interferon gamma and IL4 (Wikipedia, OMIM #188410)
  • B cells also present lipid antigen to CD1d restricted invariant NKT cells, which contributes to maintaining tolerance in autoimmunity
  • On chromosome 1q22-23 (not MHC linked)
  • Also called R3G1
  • Sole group 2 member of the CD1 family of MHC-like glycoproteins
