Identification of human iNKT cells expressing an iNKT1 and iNKT2 signature. Normalized expression of iNKT1 (A), iNKT2 (B), and iNKT17 (C) signatures in thymic iNKT cells. Color intensity and violin plots represent the composite expression score of iNKT sublineage-specific gene sets as calculated using Seurat's AddModuleScore function.
