CD1d protein is a molecule of the [https://en.wikipedia.org/wiki/Immune_system immune system]. It is 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].

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]. | CD1d protein is a molecule of the [https://en.wikipedia.org/wiki/Immune_system immune system].
