TSLP Tg expression restores splenic lymphocyte compartments in IL-7^−/− mice. (A) Absolute splenocyte numbers of IL-7^−/−, WT, and IL-7^−/− K14-TSLP Tg (12-week-old). (B) Percentages and (C) absolute cell number of CD4⁺, CD8⁺, and γδ⁺CD3⁺ T cells, and CD19⁺CD93⁻ mature B cells composed of follicular (CD23⁺ CD21⁺) and MZ (CD21^high CD23⁻) B cells are shown. Histograms represent the mean and standard deviation from analyzing 5 animals. *P < .05; **P < .005 (Student t test). (D) Gated on splenic CD4⁺ and CD8⁺ T cells, CD62L and CD44 expression is shown.
