Abstract
in English, Chinese

The tumor microenvironment (TME), the environment of tumorigenesis and tumor progression, incorporates multiple types of cells and non-cellular components. TME plays an important role in tumorigenesis and tumor progression. Due to the abnormal proliferation of tumors, the TME has a unique chemophysiology environment and complex metabolic patterns, which subsequently affects the role of immune cells. Understanding the metabolic patterns of TME can help us develop immunotherapy regimens that target TME. Microbial metabolism and lipid metabolism, the key metabolic processes of TME, have emerged as important foci of research. The metabolites released by the microbiome and the reprogramming of cellular lipid metabolism affect the subsistence of tumor and immune cells. In this review, we summarized the composition and metabolic characteristics of TME and discussed the latest research progress in microbial metabolism and lipid metabolism in TME. We also provided an update on relevant metabolic regulatory targets and immunotherapy strategies, stressing that identifying highly effective therapeutic targets, in spite of the apparent difficulty, is what future research should be focused on.

肿瘤微环境是肿瘤发生和生长的环境，包括多种细胞类型和细胞外成分，对肿瘤的发生、发展起着重要作用。由于肿瘤的异常增殖，肿瘤微环境具有特殊的理化环境，造成复杂的代谢模式，免疫细胞作用随之受到影响。理解肿瘤微环境代谢模式能帮助我们开发靶向肿瘤微环境的免疫治疗方案。微生物代谢和脂代谢是肿瘤微环境的关键代谢过程，也是目前新兴的研究热点。微生物释放的代谢产物和细胞脂代谢重编程影响肿瘤和免疫细胞的生命活动。本文概述了肿瘤微环境组成及代谢特征，讨论了近年来肿瘤微环境中的微生物代谢和脂代谢的研究进展，总结了相关代谢调控靶点和免疫治疗策略，指出找到高效的治疗靶点是肿瘤微环境治疗领域的难点和研究方向。
