Lack of Aire+CD80+ mTECs in RANK−/− mice promotes autoimmunity. Stroma-enriched adult thymus digests from WT (A) and RANK−/− mice (B) were stained for CD45, EpCAM1, Ly51, and CD80. Data are gated on CD45Ly51 cells. In C and D, tissue sections of WT and RANK−/− adult thymus were stained for keratin 5 (green) and Aire (red). Higher power magnification is shown in the bottom panels. Bars: (C and D, top) 20 μm; (C and D, bottom) 5 μm. E shows quantitation of Aire+ mTECs in sections of RANK+/− and RANK−/− thymus. F is qPCR highlighting absence of TRA expression in RANK−/− thymus (white bars) compared with WT thymus (black bars). Histological analysis of leukocytic infiltrates in the liver of nude mice (arrow) transplanted with RANK−/− dGuo-treated, but not WT thymus, is in G. (H) Immunohistochemical analysis of Rag−/− tissues using serum obtained from RANK−/− and WT transplanted nude mice. Red, autoantibody staining; blue, DAPI staining. Bars: G, 100 μm; H, 20 μm.
