HDAC2 inhibits IL-17 expression. a Knockdown of HDAC2 in cLPLs of WT mice using shRNA. ELISA was performed to measure IL-17A secretion in the culture supernatant of WT cLPLs treated with HDAC2-specific shRNA (shHDAC2) or control shRNA (shCtrl). b CD4+ T cells were isolated from WT and HDAC2f/f CD4-Cre mice and were differentiated under Th17-inducing conditions. Real-time PCR and ELISA were performed to measure IL-17A expression. c Immunoblot analysis was performed to check the knockdown of ROR-γt in CD4+ T cells isolated from HDAC2f/f CD4-Cre mice using ROR-γt-specific shRNA and differentiated under Th17-inducing conditions. d ELISA and e real-time PCR were performed to measure IL-17A expression in HDAC2f/f CD4-Cre cells treated with ROR-γt-specific shRNA or control shRNA. f Schematic drawing of model shows that SUMOylation of ROR-γt facilitates recruitment of HDAC2, which inhibits IL-17 expression. Data are from one experiment representative of three or more independent experiments with similar results. *p< 0.05 and **p< 0.01, ns non-significant (two-tail t test) error bars are S.D.
