'''CD1d protein''' is a molecule of the [https://en.wikipedia.org/wiki/Immune_system immune system], involved in presenting a lipid antigen to NKT cells. Indeed, these proteins are located on the surface of the plasma membrane of [https://en.wikipedia.org/wiki/Antigen-presenting_cell APC cells]. When the recognition between the CD1d bound to its lipid ligand and the [[TCR]] of a NKT cell occurs, the [https://en.wikipedia.org/wiki/Lymphocyte lymphocyte] turns out to be activated. Thus, the production of cytotoxic molecules such as | '''CD1d protein''' is a molecule of the [https://en.wikipedia.org/wiki/Immune_system immune system], involved in presenting a lipid antigen to NKT cells.

Thus, the production of cytotoxic molecules such as [[interleukin]]-4 and [https://en.wikipedia.org/wiki/Interferon_gamma IFN-gamma] is triggered by this activation, leading to either a Th2 or Th1 immune response respectively <ref>Joyce, S.

Therefore, CD1d proteins are precursors of the adaptive immune reaction which are key activators of the NKT cells. As a result, a deficiency of CD1d proteins may lead to a deficiency of the NKT cells functioning and thus to [https://en.wikipedia.org/wiki/Autoimmune_disease autoimmune diseases] and [https://en.wikipedia.org/wiki/Cancer cancers]. | ||
