Abstract

Hepatocellular carcinoma (HCC) is among the most common and lethal cancers worldwide and is characterized by complex metabolic and immunological processes throughout its progression. Emerging research has underscored the critical involvement of the gut microbiota and its metabolites, particularly short‑chain fatty acids (SCFAs), in regulating the hepatic immune microenvironment and contributing to the development of HCC. SCFAs play essential roles in the gut‑liver axis by supporting immune homeostasis, modulating lipid metabolism and influencing immune escape mechanisms within the liver. SCFAs are not only products of gut microbiota metabolism but also key regulators of liver metabolism and immune responses. SCFAs play both positive and negative roles in HCC. SCFAs influence T‑cell function and immune responses through the activation of G‑protein‑coupled receptors and the inhibition of histone deacetylases. The present review provided an overview of the current knowledge concerning the regulatory dual effects of SCFAs on the immune microenvironment of HCC, examines their interactions with immune cells via the gut‑liver axis and evaluated their potential as adjuncts in HCC immunotherapy, with the goal of informing future therapeutic strategies.

短链脂肪酸调节肝细胞癌进展:肿瘤免疫的代谢观点(综述)。
肝细胞癌(HCC)是世界范围内最常见和最致命的癌症之一,其特点是在其整个进展过程中具有复杂的代谢和免疫过程。新兴研究强调了肠道微生物群及其代谢物,特别是短链脂肪酸(SCFAs)在调节肝脏免疫微环境和促进HCC发展中的重要作用。scfa通过支持免疫稳态、调节脂质代谢和影响肝脏内的免疫逃逸机制,在肠-肝轴中发挥重要作用。SCFAs不仅是肠道菌群代谢的产物,也是肝脏代谢和免疫反应的关键调节因子。scfa在HCC中有积极和消极的作用。SCFAs通过激活G蛋白偶联受体和抑制组蛋白去乙酰化酶影响T细胞功能和免疫应答。本综述综述了目前关于SCFAs对HCC免疫微环境的调节双重作用的知识,研究了它们通过肠-肝轴与免疫细胞的相互作用,并评估了它们作为HCC免疫治疗辅助物的潜力,目的是为未来的治疗策略提供信息。
