概括

阻断结缔组织生长因子 (CTGF) 没有减少肺或改善呼吸器诱导肺损伤 (VILI) 的老鼠的氧化. 这项研究在这个VILI模型中发现CTGF中和没有显著的益处.

科学领域:

肺部医学肺部医学
关键的护理关键的护理
病理生理学病理生理学

背景情况:

急性呼吸困难综合征 (ARDS) 涉及气泡胀和潜在的纤维化.
机械通风可以加剧肺损伤 (VILI).
结合性组织生长因子 (CTGF) 与ARDS纤维化和血管泄漏有关.

研究的目的:

为了研究中和CTGF是否减少呼吸机诱导肺损伤 (VILI) 的肺.

主要方法:

老鼠接受LPS,然后在低或中等潮体积下进行机械通风.
鼠被用CTGF中和抗体 (FG-3154) 或安慰剂治疗.
评估了肺湿干重量比,右透度,组织病理学和可溶性RAGE.

主要成果:

维利导致氧气供应受损,肺部胀,肺炎和炎症增加.
治疗FG-3154并没有改变肺,血管透性或组织病理.
在抗体和安慰剂组之间的关键VILI标志物中没有发现显著差异.

结论:

"双重打击"的VILI模型显示炎症,氧化能力受损和肺部受伤.
在这个VILI模型中,中和CTGF并没有改善氧化或减少肺.
CTGF 中和在缓解与VILI相关的肺瘤方面并不有效.

关键词:

在ARDS中,我们使用ARDS.在CTGF中,CTGF是CTGF.湿疹和湿疹是一个问题.肺肺肺肺肺肺肺呼吸机引起的肺损伤

TGF - β Signaling Pathway

TGF - β Signaling Pathway

The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors are of three kinds RI, RII, and RIII. The RI...
