CD22
CD22，又被称为Siglec-2，普遍存在于正常B细胞和B细胞恶性肿瘤中。CD22主要表达于成熟B细胞，是具有调控B细胞激活作用的细胞表面粘附分子，有助于B细胞对抗原反应敏感性的控制。此外，有研究进一步证明了CD22表达在B细胞中具有特异性，并且在小鼠和人类中都受到发育调控。CD22作为B细胞受体（BCR）的一个共受体，通过抗原引起CD22与BCR交联，触发CD22磷酸化，使下游信号蛋白去磷酸化和失活，从而抑制BCR信号传导，防止自身免疫性疾病的发生。意味着，CD22表达或功能受损在自身免疫性疾病的发病机制中起重要作用，如系统性红斑狼疮(SLE)、类风湿性关节炎(RA)等。因此，作为限制B细胞的抗原，CD22为治疗自身免疫疾病和血液癌症中的B细胞失调提供了有效靶点。
