Invariant natural killer T (iNKT) cells recognize glycolipids as antigens and diversify into NKT1 (IFN-?), NKT2 (IL-4), and NKT17 (IL-17) functional subsets while developing in the thymus. Mechanisms that govern the balance between these functional subsets are poorly understood due partly to the lack of distinguishing surface markers. Here we identified the heparan sulfate proteoglycan syndecan-1 (sdc1) as a specific marker of naïve thymic NKT17 cells and that sdc1 deficiency significantly increased thymic NKT17 cells at the expense of NKT1 cells, leading to impaired iNKT cell-derived IFN-?, both in vitro and in vivo. Using surface expression of sdc1 to identify NKT17 cells, we confirmed differential tissue localization and interstrain variability of NKT17 cells and uncovered that NKT17 cells expressed high TCR?, preferentially use V?8, and display high sensitivity to ?-GalCer than to CD3/CD28 stimulation. These findings provide a novel non-invasive simple method for identification and viable sorting of naïve NKT17 cells from unmanipulated mice and suggest that sdc1 expression negatively regulates homeostasis iNKT cells. In addition, they lay the groundwork for investigating the mechanisms by which sdc1 regulates NKT17 cells.
