B细胞在类风湿关节炎(RA)成骨细胞(OB)功能障碍中的作用尚未得到很好的研究。在此,我们发现在两种类风湿性关节炎小鼠模型中,B细胞在靠近骨钙素+OBS的软骨下和骨内骨髓(BM)区域富含B细胞:胶原性关节炎和肿瘤坏死因子转基因小鼠。RA小鼠软骨下BM B细胞表达高水平的OB抑制因子CCL3和肿瘤坏死因子,并通过激活ERK和NF-κB信号通路抑制OB分化。RA B细胞对成骨细胞分化的抑制作用可被CCL3和肿瘤坏死因子中和所阻断,Ra B细胞中CCL3和TNF的缺失可在体内完全恢复OB功能,而B细胞去除可减轻RA小鼠的骨侵蚀和OB抑制。类风湿关节炎患者的B细胞表达CCL3和肿瘤坏死因子并抑制成骨细胞分化,CCL3和肿瘤坏死因子中和可改善这些作用。因此,B细胞通过产生多种OB抑制剂来抑制RA的骨形成。
The function of B cells in osteoblast (OB) dysfunction in rheumatoid arthritis (RA) has not been well-studied. Here we show that B cells are enriched in the subchondral and endosteal bone marrow (BM) areas adjacent to osteocalcin+OBs in two murine RA models: collagen-induced arthritis and the TNF-transgenic mice. Subchondral BM B cells in RA mice express high levels of OB inhibitors, CCL3 and TNF, and inhibit OB differentiation by activating ERK and NF-κB signaling pathways. The inhibitory effect of RA B cells on OB differentiation is blocked by CCL3 and TNF neutralization, and deletion of CCL3 and TNF in RA B cells completely rescues OB function in vivo, while B cell depletion attenuates bone erosion and OB inhibition in RA mice. Lastly, B cells from RA patients express CCL3 and TNF and inhibit OB differentiation, with these effects ameliorated by CCL3 and TNF neutralization. Thus, B cells inhibit bone formation in RA by producing multiple OB inhibitors.
