IL-34 promoted the proliferation of RA-FLSs by regulating IL-17. (A) The MTT assay was used to measure RA-FLS proliferation. RA-FLSs were treated with different concentrations of IL-34 (0 ng/ml, 25 ng/ml, 50 ng/ml and 100 ng/ml). (B) RA-FLSs were treated with IL-34 (100 ng/ml) or IL-34 (100 ng/ml) + PB (4 µM).The differences between the four groups were tested by ANOVA. Statistical comparisons between two groups were performed by t-tests. The data are expressed as the mean ± SEM. *P < 0.05, ***P < 0.001 vs the 0 group; #P < 0.05, ###P < 0.001 vs the 25 group; P < 0.05 vs the 50 group; $$$P < 0.001 vs the IL-34 group.
