CD1d expressed on bone marrow–derived cells are critical for the negative selection of NKT cells. 107 bone marrow-derived cells from WT, Tg, and CD1dKO mice were transferred into lethally irradiated recipient mice (980 rad) by intravenous injection. After 10 wk, spleen and liver lymphocytes from bone marrow chimera were isolated and analyzed by flow cytometry. (a) Absolute NKT cell numbers of liver lymphocytes and splenocytes from each group of bone marrow chimeras. (b) IL-4 production by liver lymphocytes and splenocytes from each group of bone marrow chimeras. 106 liver lymphocytes and splenocytes from indicated group of mice were cultured in the presence of 100 ng/ml of α-GalCer for 48 h. IL-4 levels in the supernatant were detected by ELISA.
