在全身性红斑狼疮(SLE)和慢性类风湿性关节炎(RA)等自身免疫性疾病患者的体内可以查到自身抗体。自身抗体的产生对机体有害,这是不应有的现象。通常机体有调节阻止其产生的能力。附图描述了有免疫力作用的T 细胞、B 细胞和巨噬细胞的分化和抗体产生的关系,可以看到抑制 T 细胞在抑制机体发生异常免疫反应中起着主要的作用。因此,如果 Autoantibodies can be detected in vivo in patients with autoimmune diseases such as systemic lupus erythematosus (SLE) and chronic rheumatoid arthritis (RA). The production of autoantibodies harmful to the body, this is an unworthy phenomenon. Usually the body has the ability to prevent it from being produced. The figure depicts the relationship between the differentiation of immune-competent T cells, B cells and macrophages and antibody production. It can be seen that the inhibition of T cells plays a major role in inhibiting the abnormal immune response in the body. So if
