Figure Lengend Snippet: PD-L1-Fc treatment affects the differentiation of uterine T helper cells in mice. (a) qPCR of the expression of IL-17a, IFn-γ, and Il-10 mRNA in the different groups. P values were calculated from one-way ANOVA followed by Tukey’s post hoc test. * P < 0.05. (b) The frequencies of CD4 + T cells producing IFN-γ or IL-17A in the decidua were determined by flow cytometry after in vitro restimulation with PMA and ionomycin. The percentages of IFN-γ+ and IL-17A + T cells are presented as the means ± s.d. of 4–6 individual mice per group. Flow cytometry gating was performed using a standardized workflow (lymphocyte → singlets → CD4 + → cytokine + ). Although representative plots were not captured for publication in this study, all analyses were conducted using identical gating parameters across groups and validated by two independent investigators. (c) After restimulation of sorted CD4 T cells (5 × 10 4 ) with anti-CD3/CD28 monoclonal antibodies (mAbs) for 24 h, the levels of IFN-γ, IL-17A or IL-10 in the cell culture supernatants were determined using ELISA. *p < 0.05; **p < 0.01 by one-way analysis of variance followed by Bonferroni correction. The data are representative of three independent experiments.
