2023年9月26日 · 该综述详细讨论了急性、慢性感染和肿瘤发生条件下CD8+ T细胞分化的异质性以及mTOR (重点阐述mTORC2/SIN1)信号通路在记忆T细胞和耗竭T细胞分化过程中的分子调控机制,为开发针对mTOR信号通路以调控CD8+ T细胞的分化并增强其免疫功能的治疗方法提供新的思路。 CD8+ T细胞作为机体抵抗外界抗原入侵的重要组成部分,其在抗病毒免疫和抗肿瘤免疫过程中均发挥重要作用。...
Regulation of CD8 + T memory and exhaustion by the mTOR …
2023年8月15日 · In this review, we focus on mammalian target of rapamycin (mTOR), particularly signaling mediated by mTOR complex (mTORC) 2 in memory and exhausted CD8+ T cells at the molecular level.
Phosphoproteomics of CD2 signaling reveals AMPK-dependent …
First, phosphoproteomics and Western blotting analyses revealed that CD2 modulated the phosphorylation of 40 kinases (table S4), including three kinases belonging to the mTOR signaling pathway, namely, mTOR (Ser 2448), ribosomal protein S6 kinase β-1 (p70-S6K) (Thr 389), and AMP-activated kinase (AMPK) (Thr 172) .
CD226 maintains regulatory T cell phenotype stability and ... - Cell …
2023年10月31日 · CD226-deficient Treg cells exhibit reduced oxidative phosphorylation and increased glycolysis rates, which are regulated by the adenosine 5′-monophosphate-activated protein kinase (AMPK)/mammalian target of rapamycin (mTOR)/myelocytomatosis oncogene (Myc) pathway, and inhibition of Myc signaling restores the impaired functions of CD226 ...
Roles of mTORC1 and mTORC2 in controlling γδ T1 and γδ T17 …
2020年1月30日 · In this study, we found that mTORC1 directs both the γδ T1 and γδ T17 differentiation of peripheral γδ T cells by the mechanisms involving glycolysis. mTORC2 promotes γδ T17 differentiation via...
mTORC1 and mTORC2 selectively regulate CD8⁺ T cell ... - PubMed
Activation of mTOR-dependent pathways regulates the specification and differentiation of CD4+ T effector cell subsets. Herein, we show that mTOR complex 1 (mTORC1) and mTORC2 have distinct roles in the generation of CD8+ T cell effector and memory populations.
Cell子刊综述:一文详细了解mTOR对细胞代谢的调节 - 知乎
2023年9月4日 · 雷帕霉素靶点 (The target of rapamycin,TOR)对于大部分学者而言都不陌生,它是一种高度保守的丝氨酸/苏氨酸蛋白激酶,在调节细胞生长、新陈代谢过程中具有核心作用。 哺乳动物TOR(mTOR)作为代谢研究中的持续热点,其在机体中的调节作用、生理作用已得到广泛的研究。 今天要给大家介绍一篇关于mTOR的综述,题为The central moTOR of metabolism。 这篇综述讨论了有关 mTOR 信号传导调节和 mTOR 对碳水化合物、核酸、脂质和蛋白质代谢 …
Roles of mTORC1 and mTORC2 in controlling γδ T1 and γδ T17 ...
The metabolism-controlled differentiation of αβ T cells has been well documented; however, the role of a metabolism program in γδ T cell differentiation and function has not been clarified. Here, using CD2-cre; mTORC1 Raptor-f/f, and mTORC2 Rictor-f/f mice (KO mice), we found that mTORC1, but not mT …
mTOR信号通路 - 知乎 - 知乎专栏
mTOR是 PI3K 相关激酶(PIKK)家族中的丝氨酸/苏氨酸蛋白激酶,形成两个不同的蛋白复合物的催化亚基,称为mTOR复合物1 (mTORC1)和2 (mTORC2)(图1A)。mTORC1由其三个核心成分组成:mTOR、Raptor(与mTOR相关的调节蛋白)和mLST8(哺乳动物致死的Sec13蛋白8,也被称为GßL)(图 ...
mTOR信号通路:细胞的调节器,药物的靶点,科学的前沿 - 知乎
2023年9月26日 · mTOR是哺乳动物 雷帕霉素 靶蛋白(mammalian target of rapamycin)的缩写,它是一种丝氨酸/苏氨酸蛋白激酶,属于 PI3K/Akt信号通路 的下游效应子。mTOR可以与不同的蛋白质形成两种复合体,即mTORC1和mTORC2,它们在细胞内有不同的定位和功能。
