Immune cells express receptors for extracellular nucleotides named P2 receptors. P2 receptors transduce signals delivered by nucleotides present in the extracellular environment. Accruing evidence shows that purinergic signalling has a profound effect on multiple immune cell responses such as T lymphocyte proliferation, chemotaxis, cytokine release, phagocytosis, Ag presentation and cytotoxicity. This makes P2 receptors an attractive target for the therapy of immuno-mediated disease and cancer.
免疫细胞表达细胞外核苷酸的受体,称为 P2 受体。P2 受体转导细胞外环境中存在的核苷酸传递的信号。越来越多的证据表明,嘌呤能信号对多种免疫细胞反应有深远的影响,如 T 淋巴细胞增殖、趋化性、细胞因子释放、吞噬作用、抗原呈递和细胞毒性。这使得 P2 受体成为免疫介导疾病和癌症治疗的有吸引力的靶点。
