The past few years have seen a surge of interest in B cell depletion therapy for patients with rheumatoid arthritis. This paper outlines the possible mechanism(s) by which B cell depletion therapy works. It is likely there is more than one mechanism and the relative importance of each mechanism depends on the target cell. These include CD20-induced apoptosis, complement dependent cytotoxicity, antibody dependent cell-mediated cytotoxicity, and selective targeting and depletion of B cell subsets. The implications of these mechanisms in the further improvement of B cell depletion therapy in rheumatoid arthritis and other autoimmune diseases are discussed.
在过去几年里,针对类风湿性关节炎患者的B细胞清除疗法引发了极大的关注。本文概述了B细胞清除疗法起作用的可能机制。可能存在不止一种机制,且每种机制的相对重要性取决于靶细胞。这些机制包括CD20诱导的细胞凋亡、补体依赖性细胞毒性、抗体依赖性细胞介导的细胞毒性以及B细胞亚群的选择性靶向和清除。本文还讨论了这些机制对进一步改进类风湿性关节炎及其他自身免疫性疾病的B细胞清除疗法的意义。
