描述 CD274,也称为PD-L1和B7-H1,是I型跨膜糖蛋白,可作为CD279(PD-1)的配体。这种相互作用被认为可以调节对微生物的反应和维持自我耐受所需的刺激和抑制信号之间的平衡。CD274以IL-2依赖性和CD279非依赖性方式参与T细胞增殖和IL-10和IFN-γ的产生。相互矛盾的数据表明,CD274可以抑制T细胞增殖和细胞因子的产生,或者增强T细胞活化。其他研究表明,CD274可能是双向信号,对其在多种细胞类型中的表达提出了有趣的意义,包括T细胞和B细胞,抗原呈递细胞和非造血细胞。 Description CD274, also known as PD-L1 and B7-H1, is type I transmembrane glycoprotein that serves as a ligand for CD279 (PD-1). This interaction is believed to regulate the balance between the stimulatory and inhibitory signals needed for responses to microbes and maintenance of self-tolerance. CD274 is involved in the costimulation of T cell proliferation and IL-10 and IFN-γ production in an IL-2-dependent and CD279-independent manner. Conflicting data has shown that CD274 can inhibit T cell proliferation and cytokine production, and alternatively, enhance T cell activation. Other studies suggest that CD274 may signal bidirectionally, raising interesting implications for its expression in a wide variety of cell types, including T and B cells, antigen-presenting cells, and non-hematopoietic cells.
