Nature Communications:已找到治疗纤维化的新靶点

2019-10-05 Allan MedSci原创

当涉及组织损伤修复时,体内成纤维细胞就会起作用。成纤维细胞产生的成肌纤维细胞通常在短期内是有益的,但当成肌纤维细胞激活失控时,它就会变坏,引起纤维化。一项由Temple大学Lewis Katz医学院(LKSOM)的研究人员完成的研究显示,成纤维细胞活化和成肌纤维细胞形成的过程会引起的线粒体钙摄取的变化。该研究于10月4日在线发表在《Nature Communications》杂志上。

当涉及组织损伤修复时,体内成纤维细胞就会起作用。成纤维细胞产生的成肌纤维细胞通常在短期内是有益的,但当成肌纤维细胞激活失控时,它就会变坏,引起纤维化。一项由Temple大学Lewis Katz医学院(LKSOM)的研究人员完成的研究显示,成纤维细胞活化和成肌纤维细胞形成的过程会引起的线粒体钙摄取的变化。该研究于10月4日在线发表在《Nature Communications》杂志上。

该研究发现,线粒体中钙的吸收减少是成肌纤维细胞分化和纤维化的主要调节剂。当线粒体钙水平下降时,细胞代谢发生变化,α-酮戊二酸的代谢产物被上调。α-酮戊二酸水平的增加反过来改变了细胞DNA的包装,改变了将成纤维细胞转化成肌纤维细胞的基因表达。

NEJM:慢性矽肺病伴进行性纤维化-病例报道

慢性矽肺病可能在吸入可吸入结晶二氧化硅多年后发展,并与一系列职业有关,包括采矿、铸造工作、水泥和混凝土生产、喷砂、砖石和陶瓷生产等。结节通常发生在肺的上部区域。除了避免环境中的二氧化硅外,没有针对慢性矽肺的特定疗法。

JACC:晚期心衰患者的成纤维化一定程度上可逆

间质纤维化是导致心衰患者收缩和舒张功能不全的重要原因之一,而其依赖于纤维母细胞到肌成纤维细胞(MyoFb)的激活和分化。近期的临床研究表明晚期心衰的纤维化是不可逆的。本研究的目的旨在评估晚期心衰MyoFb的分化程度。本研究从因缺血性心脏病或扩张型心肌病心脏移植患者的左室中分离出成纤维细胞,置于培养基中培养4-8天。细胞表型的鉴定包括功能实验、免疫染色和分化标志物的表达量检测。分析结果显示,心衰患者
