Fig. 8. SOX-5-BS deficiency in RORCE inhibits Th17 cell polarization in vitro.
a–c Splenic naïve CD4+ T cells from indicated mice stimulated under Th17 polarizing conditions for 4 days. The frequency of CD4+RORγt+ Th17 (a) and CD4+IL-17A+ Th17 (b and c) cells and MFI of RORγt (a) were measured by flow cytometry and summarized. d–f Relative mRNA expressions of RORγt (d) and IL-17A (e) genes in Th17-polarized cells and IL-17A protein in the culture supernatants (f) were measured by RT-qPCR and ELISA, respectively. g Relative mRNA expression of Sox5, RORγt, and IL-17A genes in Th17-polarized cells from indicated mice and the IL-17A protein in culture supernatants before and after Sox5 overexpression. Mean ± SEM are shown, n = 5 independent experiments, unpaired two-tailed Student’s t-test (a, c–g). Experimental mice were between 8 and 12 weeks of age, with no preference to gender and were maintained on a C57BL/6 background. Source data are provided as a Source Data file.
