摘要
自身免疫性疾病是由于机体对自身抗原失去免疫耐受而发生的一类异质性疾病。近年来,抗体药物已成为治疗自身免疫性疾病的重要选择。单克隆抗体因相对分子质量大,不易穿透实体组织而应用受限,而纳米抗体是目前已知的具有完整抗原识别能力的最小抗体片段,具有易于改造、穿透力强、能够靶向更加隐蔽的表位等特点,在自身免疫性疾病的治疗中受到了广泛关注。本文重点阐述纳米抗体在类风湿关节炎、获得性血栓性血小板减少性紫癜、系统性红斑狼疮和银屑病等疾病治疗中的应用情况,展望纳米抗体在自身免疫性疾病治疗中的应用前景。
Autoimmune disease is a kind of heterogeneous disease caused by the loss of immune tolerance to autoantigens.In recent years,antibody drug has become an important choice for the treatment of autoimmune diseases.Monoclonal antibodies are limited by their large relative molecular mass and difficult to penetrate solid tissues,while nanobodies,the smallest antibody fragment known to date with intact antigen recognition,have gained much attention in the treatment of autoimmune diseases due to their ease of modifi-cation,high penetration,and ability to target more cryptic epitopes.The review focuses on the application of nanobodies in the treat-ment of diseases such as rheumatoid arthritis,acquired thrombotic thrombocytopenic purpura,systemic lupus erythematosus,psoria-sis,and looks forward to the prospect of nanobodies in the treatment of autoimmune diseases.
