1402-NINJ1促进急性肺损伤中中性粒细胞胞外陷阱释放的研究

from 聊聊Sci

这项研究通过单细胞测序与临床验证,阐明了孔道形成蛋白 NINJ1 在急性肺损伤(ALI)过程中促进中性粒细胞胞外陷阱(NETs)释放的关键作用。研究发现,在急性呼吸窘迫综合征(ARDS)患者及模型小鼠中,NINJ1 的表达显著升高,其通过形成特定的寡聚体结构来诱导细胞膜破裂,从而释放导致肺部损伤的炎症物质。实验结果显示,通过基因技术缺失中性粒细胞中的 Ninj1,可以有效抑制 NETs 的产生,进而减轻肺组织病理损伤并降低死亡率。此外,研究确定了 K45 和 N60 两个关键位点对于该蛋白的寡聚化至关重要。综上所述,该成果揭示了 NETosis 发生的新型分子机制,并提出 NINJ1 是治疗急性肺损伤的潜在重要靶点。References:Zhong W J, Liu Y B, Yang X Y, et al.
