抗原ＣＤ4 4是一个分布极广泛的细胞跨膜糖蛋白家族 ,参与Ｔ和Ｂ淋巴细胞分化发育过程 ,介入白细胞与活化的内皮细胞结合 ,故有淋巴细胞归巢受体之称。增强Ｔ细胞的活化和增殖 ,与某些ＣＤ4 4变异体表达与肿瘤的扩散和转移密切相关。因此 ,这一专题的研究将深化对细胞粘附生物 Antigen CD4 4 is a widely distributed cell transmembrane glycoprotein family, involved in the development of T and B lymphocyte differentiation and development, involved in the combination of activated leukocytes and endothelial cells, it is said that lymphocytes homing receptors. Enhance the activation and proliferation of T cells, and some CD4 4 variants are closely related to tumor proliferation and metastasis. Therefore, the research on this topic will deepen the adhesion of cells to organisms
