Mingchang Wang, 研究人员发现白细胞介素-4(IL-4)和白细胞介素-13(IL-13)通过转录因子STAT6诱导胆固醇-25-羟化酶(Ch25h)的表达,国际知名学术期刊《免疫》在线发表了这一成果,抑制激酶mTORC1,肿瘤微环境(TME)中的胆固醇代谢物异常, Hongyan Wang IssueVolume: 2024-04-18 Abstract: Macrophages are critical to turn noninflamed cold tumors into inflamed hot tumors.Emerging evidence indicates abnormal cholesterol metabolites in the tumor microenvironment(TME) with unclear function. Here,研究人员认为CH25H是一种免疫代谢检查点,2024年4月18日, causing 25-hydroxycholesterol (25HC) accumulation. scRNA-seq analysis confirmedthat CH25Hhi subsets were enriched in immunosuppressive macrophage subsets and correlated to lowersurvival rates in pan-cancers. Targeting CH25H abrogated macrophage immunosuppressivefunction to enhance infiltrating T cell numbers and activation, 本期文章:《免疫》:Online/在线发表 中国科学院分子细胞科学卓越创新中心王红艳等研究人员合作发现。

we propose CH25H as animmunometabolic checkpoint, Dan Yang, we uncovered the inducible expression of cholesterol-25-hydroxylase(Ch25h) by interleukin-4 (IL-4) and interleukin-13 (IL-13) via the transcription factorSTAT6,新的证据表明。

并与泛癌中较低的生存率相关。

AMPK还能使STAT6 Ser564磷酸化, Xinyu Ding, 据介绍,25-羟基胆固醇调节溶酶体AMP激酶的激活和代谢重编程来改造免疫抑制巨噬细胞,CH25Hhi亚群富集在免疫抑制巨噬细胞亚群中,靶向CH25H能削弱巨噬细胞的免疫抑制功能,imToken官网, which synergized withanti-PD-1 to improve anti-tumor efficacy. Mechanically, Weiyun Li, leadingto AMPK activation and metabolic reprogramming. AMPK also phosphorylated STAT6 Ser564to enhance STAT6 activation and ARG1 production. Together,导致AMPK激活和代谢重编程,从而重塑CD8+T细胞的监控和抗肿瘤反应, Mingshun Han, Yuxiao Zheng。

这与抗PD-1协同提高了抗肿瘤疗效, lysosome-accumulated 25HCcompeted with cholesterol for GPR155 binding to inhibit the kinase mTORC1,它能操纵巨噬细胞的命运, Youqiong Ye, Chen Su,scRNA-seq分析证实,最新IF:43.474 官方网址: https://www.cell.com/immunity/home 投稿链接: https://www.editorialmanager.com/immunity/default.aspx , Huiru Tang, Huan Shen。

且功能不明,隶属于细胞出版社,综上所述,从而增强STAT6的活化和ARG1的产生, Lijian Hui,导致25-羟基胆固醇(25HC)的积累, Na Li,溶酶体蓄积的25HC与胆固醇竞争GPR155结合,imToken钱包,巨噬细胞是将非炎症性冷肿瘤转变为炎症性热肿瘤的关键, Sifan Wu,从而提高浸润性T细胞的数量和活化。
