计划耗尽
CD8+ T细胞耗竭一直被认为只发生在慢性抗原持续存在的情况下,如癌症或慢性病毒感染。然而,现在发表在《自然》杂志上的两篇论文表明,这些细胞及其前体存在于小鼠急性淋巴细胞性脉络丛脑膜炎病毒感染的早期阶段。在其中一项研究中,他们还在病毒感染的早期慢性前阶段检测到耗尽T细胞(Tpex)的病毒特异性干样前体,这种前体会继续变成慢性感染。使用诸如命运定位和过继转移等方法,作者发现这些细胞可以通过在慢性抗原暴露期间保持茎样表型或在急性感染中转换为(或生长)中枢记忆样T细胞来适应环境。急性感染中Tpex细胞的维持似乎是由高亲和力T细胞受体连接介导的,而不是由慢性抗原暴露介导的。总之,这些论文支持这样一种观点,即T细胞衰竭不是病毒感染中的一种功能失调状态,而是一种高度调节的程序,可以对抗不同的病毒和感染条件。原始参考文献:Nature https://doi.org/10.1038/s41586-024-08451-4 (2025);Nature https://doi.org/10.1038/s41586-024-08562-y (2025)

期刊介绍: Nature Immunology is a monthly journal that publishes the highest quality research in all areas of immunology. The editorial decisions are made by a team of full-time professional editors. The journal prioritizes work that provides translational and/or fundamental insight into the workings of the immune system. It covers a wide range of topics including innate immunity and inflammation, development, immune receptors, signaling and apoptosis, antigen presentation, gene regulation and recombination, cellular and systemic immunity, vaccines, immune tolerance, autoimmunity, tumor immunology, and microbial immunopathology. In addition to publishing significant original research, Nature Immunology also includes comments, News and Views, research highlights, matters arising from readers, and reviews of the literature. The journal serves as a major conduit of top-quality information for the immunology community.
