摘要:

环磷酸鸟苷酸合成酶[Cyclic guanosine monophosphate-adenosine monophosphate(GMP-AMP) synthase, cGAS蛋白]-干扰素刺激因子(Stimulator of interferon genes, STING蛋白)(cGAS-STING)信号通路是识别细胞质中异常DNA、 激活先天免疫应答系统的重要通路. cGAS蛋白在识别细胞质内异常DNA后, 可催化三磷酸腺苷(ATP)和三磷酸鸟苷(GTP)合成环状鸟苷酸二磷酸腺苷(Cyclic GMP-AMP, cGAMP). cGAMP作为第二信使激活STING蛋白, 促进I型干扰素的释放, 从而引起一系列免疫反应. cGAS-STING通路可以调控肿瘤的转移和增长, 参与抗肿瘤的先天免疫反应, 探究cGAS-STING通路的作用机制在肿瘤免疫治疗中具有重要意义. 本综合评述介绍了cGAS-STING通路的作用机制, 概述了目前在抗肿瘤免疫治疗中激活cGAS-STING通路的各类策略.

Abstract:

The cyclic guanosine monophosphate-adenosine monophosphate(GMP-AMP) synthase(cGAS protein)- stimulator of interferon genes(STING protein)(cGAS-STING) signaling pathway is a crucial pathway for recognizing abnormal DNA in the cytoplasm and activating the innate immune response system. After recognizing abnormal DNA in the cytoplasm, cGAS protein can catalyze the synthesis of cyclic guanosine diphosphate adenosine(cyclic GMP-AMP, cGAMP) from adenosine triphosphate(ATP) and guanosine triphosphate(GTP). cGAMP, as a second messenger, activates the stimulator of interferon gene(STING protein), promoting the release of type I interferons and thus initiating a series of immune responses. The cGAS-STING pathway can regulate tumor metastasis and growth, participate in anti-tumor innate immune responses, and exploring the mechanism of action of the cGAS-STING pathway is of great significance in tumor immunotherapy. This review introduces the mechanism of action of the cGAS-STING pathway and summarizes various strategies currently used to activate the cGAS-STING pathway in anti-tumor immunotherapy.
