Abstract/OtherAbstract:
CD1d is an MHC class I-like molecule that presents glycolipid Ags to types I and II NKT cells. The YxxI motif in the cytoplasmic tail of CD1d contributes to its intracellular localization to the endolysosomal compartment and is important for Ag presentation to type I NKT cells. In this study, we identified the (327-329)RRR motif in CD1d and showed that it is critical for the control of CD1d intracellular trafficking and Ag presentation. The replacement of the arginines in this motif with alanines resulted in the extensive accumulation of CD1d in lysosomes but did not affect the cell surface expression. The defect in its cellular localization was accompanied by defects in Ag presentation to both type I and type II NKT cells. These results demonstrated that the (327-329)RRR motif of CD1d is required for proper cellular distribution of CD1d and optimal Ag presentation to both type I and type II NKT cells.
