概括

缺血-再输液损伤会导致脏损伤. 抑制真空膜蛋白1 (VMP1) 减少了近端管道损伤,这表明VMP1在这个过程中不会通过自保护脏.

科学领域:

腎臟病學 (nephrology) 是一種醫學.
细胞生物学细胞生物学
分子医学是分子医学.

背景情况:

缺血-再输液 (I/R) 损伤是慢性病和衰竭的关键因素.
靠近管 (PT) 形态,包括刷边缘损失,迅速受到缺血压力的影响.
空腔膜蛋白1 (VMP1) 调节自,这是一个在I/R损伤中不清楚作用的过程.

研究的目的:

研究VMP1在缺血-再输液损伤中的作用.
为了确定VMP1-介导的自能否提供对I/R诱导的近道管损伤的保护.

主要方法:

成年雄性Sprague-Dawley大鼠通过静脉注射VMP1向或混合GapmeR.
动物接受了30分钟的缺血或缺血,随后进行24小时的再输血.
对皮组织进行了分析,以检测VMP1的表达,自标志物和靠近管管的形态.

主要成果:

在缺血后,VMP1在皮组织中迅速升级.
在缺血和再注射后抑制VMP1减弱的近接管边缘损失.
在再注射后,VMP1抑制并没有改变自标志物.

结论:

空腔膜蛋白1 (VMP1) 的上调与脏缺血-再输液损伤期间近道管损伤有关.
抑制VMP1可以减轻近道管损伤,而不依赖于自标志物的变化.
这表明VMP1不能提供自介导的保护,防止近端管道中的脏I/R损伤.

关键词:

这就是VMP1的原因.自自是自的过程.据报道,米R-21的发射器是米R-21 靠近的管道靠近的管道缺血的再注射损伤伤害的缺血.

ATP Driven Pumps III: V-type Pumps

ATP Driven Pumps III: V-type Pumps

V-type pumps are ATP-driven pumps found in the vacuolar membranes of plants, yeast, endosomal and lysosomal membranes of animal cells, plasma membranes of a few specialized eukaryotic cells, and some prokaryotes. They are also known as the V1Vo-ATPase, that couple ATP hydrolysis to transport protons against a concentration gradient.
The peripheral or cytosolic V1 domain with eight subunits is involved in ATP hydrolysis. The integral or transmembrane V0 domain containing at least five subunits...
