B淋巴细胞在类风湿性关节炎的发病机制中起着几个关键作用。它们是类风湿因子和抗瓜氨酸蛋白抗体的来源,这些抗体有助于免疫复合物的形成和关节中的补体激活。B细胞也是非常有效的抗原呈递细胞,并且可以通过共刺激分子的表达促进T细胞活化。B细胞均响应并产生趋化因子和细胞因子,所述趋化因子和细胞因子促进白细胞浸润到关节中、异位淋巴结构的形成、血管生成和滑膜增生。类风湿性关节炎B细胞去除疗法的成功可能取决于所有这些不同功能的破坏。
B lymphocytes play several critical roles in the pathogenesis of rheumatoid arthritis. They are the source of the rheumatoid factors and anticitrullinated protein antibodies, which contribute to immune complex formation and complement activation in the joints. B cells are also very efficient antigen-presenting cells, and can contribute to T cell activation through expression of costimulatory molecules. B cells both respond to and produce the chemokines and cytokines that promote leukocyte infiltration into the joints, formation of ectopic lymphoid structures, angiogenesis, and synovial hyperplasia. The success of B cell depletion therapy in rheumatoid arthritis may depend on disruption of all these diverse functions.
