NOD2 and CD1d play a key role in innate immunity by recognizing conserved molecular patterns of pathogens. While NOD2−/− and CD1d−/− mice display structural and functional alterations in Paneth cells, animal studies have reported no impact of NOD2 or CD1d deficiency on experimental colitis. NOD2 mutations increase the susceptibility to inflammatory bowel diseases and the CD1d bound to α-galactosylceramide [α-GalCer] alleviates intestinal inflammation. We evaluated the effect of CD1d modulation on experimental colitis in NOD2−/− mice.
