概述正常机体内存在适当的机制通过淋巴系统等来防止将自身成分识别为抗原,一旦这种机制受到破坏,机体将自身某些成分识别为抗原而形成自身抗体或致敏淋巴细胞,该过程叫自身免疫反应。自身免疫反应不等于自身免疫性疾病,也不一定引起自身免疫性疾 Overview In the normal body there is an appropriate mechanism to prevent the identification of self-components as antigens by the lymphatic system, etc. Once this mechanism is disrupted, the body recognizes some of its own constituents as antigens and forms autoantibodies or sensitized lymphocytes, a process called Autoimmune reaction. Autoimmune reactions do not equal autoimmune diseases, it does not necessarily cause autoimmune diseases
