摘　　要：多发性骨髓瘤(MM)是一种骨髓浆细胞恶性增殖性疾病。免疫抑制性微环境是导致MM患者抗肿瘤免疫监视功能受损,恶性浆细胞免疫逃逸的重要机制之一。调节性免疫细胞被认为是免疫抑制性微环境的重要组成部分,其中调节性B细胞(Bregs)是近年来发现的一种特殊类型的B细胞,可通过分泌多种抑制性可溶性细胞因子及与细胞间直接接触而发挥免疫抑制作用。MM骨髓微环境中Bregs的比例升高,可能通过分泌IL-10、抑制自然杀伤细胞功能等机制参与免疫抑制性骨髓微环境的形成,进而影响MM的治疗反应和预后,Bregs有望成为MM的潜在免疫治疗靶点。笔者主要就Bregs的表型、来源、免疫调节机制及其在MM中的研究进展进行综述。Multiple myeloma(MM)is a malignant proliferative disorder of bone marrow plasma cells.Suppressive immune microenvironment is one of the important mechanisms for the impaired anti-tumor immune surveillance in MM patients,leading to the immune escape of malignant plasma cells.Regulatory immune cells are considered to be an important part of the suppressive immune microenvironment,and regulatory B cells(Bregs),as a special type of B cells discovered in recent years,can exert immunosuppressive effects mainly through the secretion of various inhibitory soluble cytokines and direct contact with cells.The increased proportion of Bregs in the bone marrow microenvironment of MM may participate in the formation of immunosuppressive bone marrow microenvironment by screting IL-10 and inhibiting the function of natural killer cells,thereby affecting the therapeutic response and prognosis of MM,so Bregs is expected to become a potential immunotherapeutic target of MM.This article mainly reviews the phenotype,source,immunomodulatory mechanisms and research progress of Bregs in MM.
