1、T细胞衰竭的渐进发展 Progressive development of T cell exhaustion. Exhausted耗竭T细胞是T细胞分化的独特细胞系,来源于CD127+记忆前体细胞,在表型和机制上与其他T细胞功能障碍(如无能anergy和衰老senescence)不同。 感染后,幼稚T细胞被抗原、共刺激(co-stimulation)和炎症激活,它们呈指数级增殖,形成效应群体。 大多...

The role of other co﹊nhibitory molecules and their individual contribution to T cell dysfunction in liver cancer, however, remain largely elusive. Here we perform for the first time a comprehensive mRNA profiling of CD8 T cells in a murine model of autochthonous liver cancer by comparing the ...
Chronic antigen stimulation during viral infections and cancer can lead to T cell exhaustion, which is characterized by reduced effector function and proliferation, and the expression of inhibitory immune checkpoint receptors. Recent studies have demonst
2. 发现耗竭 T 细胞特异表达的 marker——LAYN 由于长期暴露于持续性抗原和炎症,精疲力竭的肿瘤浸润 T 淋巴细胞(TIL)逐渐失去效应功能,即发生耗竭(T Cell Exhaustion),TIL 功能失调,记忆 T 细胞特征也开始缺失,失去杀死肿瘤的能力,免疫系统遭受破坏。

The expression of OX40 (TNFRSF4, CD134), first described as a T cell activation marker, can be induced on activated CD4 and CD8 T cells as well as on several other lymphoid and non-lymphoid cells. A slight expression can be noticed within the first hours of T cell activation in vitro...
However, little is known about the role of cholesterol in the metabolic regulation of T cell exhaustion and the expression of the related checkpoints. In this study, we showed that cholesterol is enriched in the tumor microenvironment and induces CD8+ T cell expression of checkpoints and CD8+ ...
TEMpatrol peripheral tissues and provide rapid effector function upon reactivation [15]. Single-cell-based experiments suggest a progressive maturation of T cells from naive via TCMand TEMto TEMRAcells that are associated with chronic activation and display features of exhaustion such as impaired cytokin...
Tcell exhaustion Covid-19 Co-inhibitory receptors Transcription factors 1. Introduction A type of coronavirus infection called SARS-CoV-2, designated by the WHO as Coronavirus 2019 (COVID-19), has become a global crisis and has rapidly spread throughout the world since its outbreak (Ludwig and...
