近年来,肿瘤微环境(tumor microenvironment, TME)中癌细胞的免疫逃逸机制引起了广泛关注。在正常情况下,免疫系统,尤其是T细胞,能够识别并清除异常的癌细胞。然而,癌细胞为了生存和增殖,发展出了多种复杂的机制来躲避免疫系统的攻击,其中包括代谢重编程和线粒体功能障碍等策略。研究表明,癌细胞会通过影响浸润肿瘤的淋巴细胞(TILs)的代谢状态,削弱其抗肿瘤免疫功能。然而,这些过程的 ...

黑色素瘤和肺部样本分析表明,线粒体作为细胞的能量引擎,可以从癌细胞跳到T细胞。这些转移的线粒体在其DNA中携带功能错误,干扰了T细胞的能量产生和功能过程。线粒体对包括T细胞在内的细胞提供能量至关重要,而且T细胞在很大程度上依赖于能量产生来对抗癌症。
When a tumor develops, it creates a structure around itself called the tumor stroma, within which blood and lymphatic vessels ...
【导读】利用核糖核酸酶靶向嵌合体(RiboTACs)降解RNA,是一种很有前景的癌症治疗方法。然而,潜在的脱靶降解是一个严重的问题。在这项研究中,团队设计了一种能触发肿瘤微环境激活的RiboTAC。2025年2月3日,苏州大学的研究团队在期刊《Nat ...
鳞状细胞癌与基底细胞癌均来自于角质形成细胞的癌变,黑色素瘤来源于黑色素细胞癌变,因此在第一部分内容分析BCC,SCC,黑色素瘤细胞生态图谱后,研究团队将目光聚焦于角质形成细胞以及黑色素细胞。健康角质形成细胞和肿瘤角质形成细胞的二级聚类导致明显分离的健 ...
