The ligands that can be presented by CD1d to NKT or other CD1d-restricted T cells are very specific. Only a narrow set of molecules can bind its recognition site. Thus, it limits the risk of other similar molecules or binding CD1d proteins and ensures that the immune response is accurate. Among these molecules are included glycolipids from a marine sponge, bacterial glycolipids, normal endogenous glycolipids, tumor-derived phospholipids and glycolipids, and nonlipidic molecules<ref>Brutkiewicz, R.

The presence of high amount of CD1d proteins on the cell surface of NKT cells gives rise to a novel type of NKT cells. This larger amount of CD1d proteins allows the Cd1d high NKT cells to bind more alpha-galactosylceramide molecules and therefore to can produce greater levels of interleukin-4 and INF-gamma molecules leading to possible therapeutical effects.
