产品介绍    The CD23 antigen is the low affinity IgE Fc receptor, which is a 49 kDa protein with 38 and 28 kDa fragments. It is expressed on most mature, conventional B cells (but not on peritoneal CD5+ B cells), and can also be found on the surface of T cells, macrophages, platelets and EBV transformed B lymphoblasts. Expression of CD23 has been detected in neoplastic cells from cases of B cell chronic Lymphocytic leukemia. CD23 is expressed by B cells in the follicular mantle but not by proliferating germinal centre cells. CD23 is also expressed by eosinophils. CD23 is distinct from the high affinity IgE receptors found on basophils and mast cells, which mediate allergic reactions. The low affinity receptors are thought to play a role in isotype specific immunoregulation. The regulation of CD23 surface expression appears to be integral with the complex IgE system, which involves interactions of cells, cytokines, antibodies and regulatory factors. CD23 has been described as a “membrane bound cytokine," in that the soluble cleavage products of CD23 are themselves able to act as cytokines in vitro.    

CD23是一种II型跨膜糖蛋白，是存在于B细胞表面的IgE受体。在慢性B淋巴细胞白血病（CLL）和小B细胞淋巴瘤（SLL）为阳性，套细胞淋巴瘤和小核裂淋巴细胞淋巴瘤阴性。也表达于外周血B细胞的某些亚型、B淋巴细胞和EB病毒转染的B淋巴瘤细胞系。CD23是慢性B淋巴细胞白血病，小B细胞淋巴瘤诊断和鉴别诊断有用的标记物。
