复发性口炎又称复发性阿弗他、复发性口疮,是一种常见的口腔粘膜病,由于病因不明确,到目前还没有有效疗法。近年来随着免疫学研究的迅速发展,给本病病因的探索开辟了新的途径,机体的免疫状态取决于免疫活性细胞的存在和功能。如果缺少产生各种免疫效应因子的胸腺依赖淋巴细胞(即T细胞)、缺少产生抗体(免疫球蛋白)的囊淋巴细胞(即B细胞)或混合缺少,则发生免疫缺陷疾病,分别称之为细胞 Recurrent stomatitis, also known as recurrent aphthous, recurrent aphtha, is a common oral mucosal disease, due to the etiology is not clear, so far there is no effective therapy. In recent years, with the rapid development of immunological research, to explore the cause of this disease has opened up new avenues, the immune status of the body depends on the presence and function of immune cells. Immunodeficiency diseases occur in the absence of thymus-dependent lymphocytes (ie, T cells) that produce various immune effector factors, in the absence of antibody-producing (immunoglobulin) -containing cystic lymphocytes (ie, B-cells) cell
