PG - 441-449 LID - 10.1111/sji.12550 [doi] AB - Dendritic cells (DCs) are critical regulators of immune responses. This study was to observe the effect of DCs from peripheral blood on the differentiation of Th17 in patients with rheumatoid arthritis (RA). Peripheral blood samples were collected from 30 patients with RA and 20 healthy controls, respectively. Flow cytometry results showed that in contrast to Treg cells, the proportion of Th17 cells in T cells and the Th17/Treg ratio were both increased in patients with RA. The RT-PCR results showed that Foxp3、ROR gammat and miR-363 expression in PBMC of patients with RA were reduced, but the ITGAV expression was increased, which was negatively related to miR-363 expression. IL-17, TGF-beta and IL-6 levels detected by ELISA were increased in peripheral blood serum of patients with RA. Moreover, we noted that the CD11C(+) alphanu(+) /CD11C(+) DCs ratio was obvious increased in patients with RA and has positive correlation to the Th17/Treg ratio. In cocultured system, Th17 cell differentiation was significantly inhibited in the presence of ITGF-beta suggesting that Th17 cell differentiation was controlled by active TGF-beta (aTGF-beta). After DCs transfecting with miR-363 mimics and cocultured with T cells, Th17 cell number, IL-17 level and ROR-gammat expression were significantly reduced in the presence of latent TGF-beta (ITGF-beta). In addition, the integrin alphav protein expression was both reduced in the presence of aTGF-beta or ITGF-beta. These data demonstrated that DCs induced Th17 cell differentiation through miR-363/Integrin alphav/TGF-beta pathway in patients with RA.
