17014832 Lee A, Farrand KJ, Dickgreber N, Hayman CM, Jurs S, Hermans IF, Painter GF: Novel synthesis of alpha-galactosyl-ceramides and confirmation of their powerful NKT cell agonist activity. Carbohydr Res. 2006 Dec 11;341(17):2785-98. Epub 2006 Oct 2.

alpha-Galactosyl-ceramide (1) has been identified as a powerful modulator of immunological processes through its capacity to bind CD1d molecules and specifically activate invariant natural killer (NK)-like T cells (iNKT cells).
This paper describes the synthesis of 1, the analogous alpha-galactosyl-ceramide 3, and its short chain analogue 'OCH' (2), by use of the 4,6-di-O-tert-butylsilylene (DTBS) protecting group to produce a powerful alpha-galactosylating agent.

Furthermore, IFN-gamma production by NKT cells requires longer T cell receptor stimulation than is required for IL-4 production by NKT cells stimulated either with immobilized mAb to CD3 or with immobilized "alphaGC-loaded" CD1d molecules.

NKT cells bearing an invariant TCR (iNKT cells) restricted by nonpolymorphic CD1d molecules may constitute a readily available source of help for DC.

Invariant natural killer T (iNKT) cells are a subpopulation of T cells that are reactive with glycolipids that are bound by CD1d antigen-presenting molecules. alpha-Galactosylceramide (alpha-GalCer) is a synthetic glycolipid that is a potential treatment for several autoimmune diseases, infectious diseases and cancer.

Invariant natural killer T (iNKT) cells are an attractive therapeutic target in autoimmune diseases, since they play a major role in immune regulation. iNKT cells recognize glycolipid antigens presented by CD1d molecules that resemble the non-polymorphic MHC class I protein. alpha-galactosylceramide (alpha-GalCer) isolated from marine sponge has long been used as a prototype iNKT cell ligand in the laboratory.
