摘要:

CD300家族作为免疫球蛋白(Ig)超家族的重要成员,具有保守的Ig结构域和多样化的胞内信号基序,广泛存在于各类免疫细胞及肿瘤细胞中,因不同亚型结构组成存在差异,该家族成员分化为抑制性或激活性受体,表现出功能的异质性,在肿瘤免疫微环境中扮演双重角色,既可促进免疫激活,也可介导免疫抑制。在肿瘤免疫微环境中直接或间接调控髓系细胞(巨噬细胞、树突状细胞、多形核样的髓系来源抑制性细胞)与淋巴细胞(自然杀伤细胞、T细胞)的功能,成为肿瘤免疫逃逸的关键节点。从CD300家族调节免疫细胞发挥抗肿瘤作用出发,对其生物学功能及其与肿瘤发生发展的相关性进行综述,可为肿瘤免疫治疗及耐药提供新的研究思路。

Abstract:

As an important member of the immunoglobulin (Ig) superfamily, the CD300 family possesses conserved Ig domains and diverse intracellular signaling motifs, and is widely present in various immune cells and tumor cells. Due to differences in the structural composition of different subtypes, members of this family are classified into inhibitory or activating receptors, exhibiting functional heterogeneity. They play a dual role in the tumor immune microenvironment: they can either promote immune activation or mediate immune suppression. By directly or indirectly regulating the functions of myeloid cells (macrophages, dendritic cells, polymorphonuclear-like myeloid-derived suppressor cells) and lymphocytes (natural killer cells, T cells) in the tumor immune microenvironment, the CD300 family serves as a key node in tumor immune escape. Based on the anti-tumor effect of CD300 family regulating immune cells, this article reviews the biological functions of CD300 family and its correlation with tumor occurrence and development, which can provide new research ideas for tumor immunotherapy and drug resistance.
