背景情况:

瘤亡因子 (TNF) 是炎症的关键媒介,可以诱导全身炎症反应综合征 (SIRS).
严重SIRS模型对于理解器官衰竭和死亡率至关重要.
导致TNF致死的精确机制,特别是最初的炎症触发物与器官衰竭之间的联系,需要进一步阐明.

研究的目的:

调查死细胞灭绝在TNF诱导的致死性中的作用.
为了确定负责TNF治疗小鼠死亡的主要器官.
阐明分子机制,将损伤与心脏功能障碍和死亡联系起来.

主要方法:

在小鼠体内和体外生理分析.
战略性脑切除术,以评估脑的作用.
对亡,损伤相关分子模式 (DAMPs) 和caspase-8激活的分析.

主要成果:

盲目中的亡在接受TNF治疗的小鼠中启动了死亡过程,但不是直接的死亡原因.
心脏功能障碍下游的损伤是死亡的最终原因.
通过caspase-8激活,TNF和CECAL DAMPs协同损害心脏内皮细胞,从而损害透缩功能.

结论:

心脏内皮损伤,由TNF和DAMPs从死细胞细胞触发,是TNF诱导致死性的关键调解者.
这项研究发现了一种新的途径,即最初的肠道损伤会导致致命的心脏功能障碍.
这些发现为TNF介导的器官衰竭和死亡的复杂病理生理学提供了新的见解.

Drugs for Treatment of Crohn's Disease in IBD Using Biologic Agents: Anti-TNF

Tumor Necrosis Factor (TNF), a proinflammatory cytokine, contributes significantly to the inflammation seen in Crohn's disease. It exists as soluble TNF and membrane-bound TNF, with actions mediated through TNF receptors (TNFR). TNFR activation leads to the release of proinflammatory cytokines, T-cell activation, collagen production, and leukocyte migration, all contributing to inflammation in Crohn's disease. Anti-TNF monoclonal antibodies, namely infliximab (Remicade), adalimumab...
