1074-间质性肺疾病空间转录组图谱与纤维化驱动因子研究

from 聊聊Sci

这项研究利用单核 RNA 测序与空间转录组学技术,构建了间质性肺疾病(ILD)的高分辨率细胞图谱。研究者识别出一种由异常过渡态肺泡上皮细胞与促纤维化成纤维细胞构成的致病性细胞群落,揭示了肺部正常组织向纤维化转变的病理过程。实验证实,TGF-β、IL-1β 和 TNF-α 这三种炎症因子共同驱动了肺泡细胞的恶性分化。此外,研究还发现转录因子 NFATC4 在成纤维细胞向肌纤维细胞转化中起到了关键调节作用。这些发现为理解肺纤维化的分子驱动机制提供了重要见解,并确定了潜在的治疗靶点。该成果通过整合组织病理学与多组学数据,详尽描绘了疾病状态下肺部结构的重塑与空间布局的紊乱。References:Jaiswal A, Kooistra T, Pokatayev V, et al.
