1045-T细胞耗竭的多维调控机制与重塑策略
from 聊聊Sci
这篇文章探讨了T细胞耗竭的多维调控机制，揭示了该过程是由表观遗传、表观转录组与代谢网络共同驱动的。研究指出，长期接触抗原和压抑的肿瘤微环境会导致T细胞功能丧失，但通过调节核心代谢物或靶向特定的染色质修饰酶，这种退化状态可以被逆转。文章重点介绍了利用CRISPR筛选和细胞因子强化等先进技术，旨在将耗竭的T细胞重新编程为具有更强杀伤力的干细胞样表型。为了提高安全性，作者建议采用瞬时调节策略，以替代永久性的基因删除，从而在增强抗肿瘤疗效的同时降低恶性增殖的风险。这些发现为优化CAR T细胞疗法和开发新型癌症免疫治疗方案提供了关键的理论路线图。References:Slater C, Simon A, Laprie-Sentenac M, et al.
