急性肺损伤 (ALI) 的发病因子仍然不完全理解.
干扰素基因刺激器 (STING) 和铁死都与ALI有关.
在脂聚糖 (LPS) 诱导的ALI中,STING和铁亡之间的相互作用还没有得到很好的定义.

研究的目的:

调查LPS诱导的ALI中STING和铁亡之间的关系.
阐明STING在ALI期间调节铁亡中的作用.
探索ALI的潜在治疗点.

主要方法:

在模型系统中利用脂聚糖 (LPS) 诱导急性肺损伤 (ALI).
采用了STING淘汰模式和铁灭抑制剂/诱导剂.
评估了肺炎,上皮细胞损伤和铁亡标志物.
分析了STAT3激活路径.

主要成果:

通过LPS刺激,可以激活STING和ferroptosis.
刺痛淘汰和ferroptosis抑制显著降低了肺炎和上皮损伤.
刺痛淘汰会降低炎症和铁亡,而铁亡诱导剂则会逆转这种缓解.

Necrosis

Necrosis

Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become...
