The mRNA expression of T-bet, GATA-3, RORγT and FOXP3 in synovial biopsies of the knee joints (n=3 mice/group) were measured by QPCR (A) The mRNA expression of IFNy, IL-17A, IL-17F, IL-21, IL-22 and IL-10 are shown (B). The knee joint synovium was dissected and prepared for enzymatic digestion. The cells were incubated with PMA/ionomycine and Golgiplug for 5 hours before flowcytometric analysis (n=6 mice/group) and stained for CD3, IL-17, and IFN-γ. Representative dot plots of the isolated cells gated on CD3+ are shown (C). The mean percentage of isolated IFN-γ and IL-17 producing T cells (CD3+ population) are shown (D). Results are mean ± SEM; ns=non significant *=P<0.05, **=P<0.01, by one-way ANOVA.
