Normalization of autoimmune phenotype of IL-2Rα− mice by transgenic expression of Cyclon. (A) Spleens from 7-week-old IL-2Rα+, Cyclon-Tg IL-2Rα+, IL-2Rα−, and Cyclon-Tg IL-2Rα− mice. (B) Cell numbers of splenocytes, CD4+, and CD8+ splenic T cells, and cells in inguinal lymph nodes from IL-2Rα+, Cyclon-Tg IL-2Rα+, IL-2Rα−, and Cyclon-Tg IL-2Rα− mice. (C) Expression of CD44 on CD4+ and CD8+ splenic T cells from IL-2Rα+, Cyclon-Tg IL-2Rα+, IL-2Rα−, and Cyclon-Tg IL-2Rα− mice. (D) Transgenic expression of Cyclon decreases IL-17 in serum of IL-2Rα− mice. Serum concentrations of IL-17 were analyzed in 7-week-old IL-2Rα+, Cyclon Tg IL-2Rα+, IL-2Rα−, and Cyclon TgIL-2Rα− mice by enzyme-linked immunosorbent assay.
