Expression of IL-2Rβ (CD122) and IL-7Rα (CD127) in iNKT cells. (A) Histogram shows mean ± SD frequency of CD122 and CD127 expression in iNKT cells from CD8-depleted thymus (n = 8), CB (n = 6), and adult PBMCs (n = 10). Data compared to that in thymus. (B) Representative diagrams show distribution of CD122 (left) and CD127 (right) expression in CD4⁺ versus CD4^- cells after gating on 6B11⁺ events in adult PBMCs.
