The mouse fibroblast cell line 3T3 was cultured with each of mIL-17A, mIL-17B, mIL-17C, or mIL-17F for 24 h, and the expressions of inflammatory cytokines were measured by quantitative PCR.

PECs were cultured with each of mIL-17A, mIL-17B, mIL-17C, or mIL-17F for 24 h, and the expressions of inflammatory cytokines were measured by quantitative PCR. C, The secreted IL-6 and TNF- levels in the supernatants of 3T3 and PECs were measured by ELISA. Error bars indicate SD. The data are representative of three independent experiments. Significance of differences between control (medium) and each IL-17 family was determined; , p 0.05.

GFP-gated IL-17 family-transduced (mIL-17A, mIL- 17B, mIL-17C, or mIL-17F) Ba/F3 cells were analyzed for IL-17A, IL- 17B, IL-17C, or IL-17F expression compared with GFP-gated empty vector (pMIG)-transduced Ba/F3 cells.

Each of IL-17 family genes was transduced to BM cells with retrovirus vector and transferred to lethally irradiated mice. A, The intracellular expression of IL-17A protein in the spleen of IL-17A BM chimeric mice 8 wk after BM transplantation. The percentage of GFP cells expressing IL-17A is indicated. The data are representative of three independent experiments. B, The concentration of IL-17A protein in the serum of IL-17A BM chimeric mice (n 6) and control mice (pMIG BM chimeric mice) (n 6). The levels of IL-17A were measured by ELISA.

Incidence of CIA and arthritis scores in IL-17A and IL-17F BM chimeric mice (A and B), and in IL-17B and IL-17C BM chimeric mice (C and D). Mice were immu- nized with BCII 8 wk after the BM transplantation.
