[structures: see text] The phytosphingosine-containing alpha-galactosylceramides (alpha-GalCers), KRN7000 and OCH, have been shown to activate NKT cells via interaction with CD1d, a member of the CD1 family of antigen presenting proteins.

Although T cells were previously believed to recognize only peptide antigen associated with the major histocompatibility complex (MHC), recent studies have shown that there are unique T cells specialized for recognition of lipid or glycolipid antigens bound to the MHC class I-like CD1 molecules (CD1a, b, c or d).

Compared with other CD1d-sphingolipid structures, PIM2 has an increased number of polar interactions between its headgroup and CD1, but reduced specificity for the diacylglycerol backbone.
