Ischemia-reperfusion injury (IRI) is increased after transplantation of steatotic livers. Since those livers are increasingly used for transplantation, protective strategies must be developed. Reactive oxygen species (ROS) play a key role in hepatic IRI. In lean organs, glutathione (GSH) is an efficient scavenger of ROS, diminishing IRI. The aim of this study was to evaluate whether GSH also pr...
Ripk3-required necroptosis and mitochondria-mediated apoptosis are the predominant types of cell death that largely account for the development of cardiac ischemia reperfusion injury (IRI). Here, we explored the effect of Ripk3 on mitochondrial apoptosis. Compared with wild-type mice, the infarcted area in Ripk3-deficient (Ripk3-/-) mice had a relatively low abundance of apoptotic cells. Moreov...
Oxidative stress is known as one of the main contributors in renal ischemia/reperfusion injury (IRI). Here we hypothesized that Micro-vesicles (MVs) derived from human Wharton Jelly mesenchymal stromal cells (hWJMSCs) could protect kidney against IRI through mitigating oxidative stress. MVs isolated from hWJMSCs conditioned medium were injected intravenously in rats immediately after unilateral...
Ischemia reperfusion injury (IRI) occurs in almost every liver surgery and is associated with the reduction of the liver blood flow. Ischemia impairs liver function and can even cause liver failure following surgery. The present study aimed to identify a new molecular target allowing the reduction of IRI and explore the related cellular mechanism. Adenovirus (~2.5x10(12) viral particles) bearin...
Background. Several approaches have been proposed to pharmacologically ameliorate hepatic ischemia/reperfusion injury (IRI). This study was designed to evaluate the effects of a preconditioning oral nutritional supplement (pONS) containing glutamine, antioxidants, and green tea extract on hepatic warm IRI in pigs. Methods. pONS (70 g per serving, Fresenius Kabi, Germany) was dissolved in 250 mL...
Liver resection is commonly performed under ischemic conditions, resulting in two types of insult to the remnant liver: ischemia reperfusion injury (IRI) and loss of liver mass. Complement inhibition is recognized as a potential therapeutic modality for IRI, but early complement activation products are also essential for liver regeneration. We describe a novel site-targeted murine complement in...
BACKGROUND Activins, members of the TGF-β superfamily, are key drivers of inflammation and are thought to play a significant role in ischemia-reperfusion injury (IRI), a process inherent to renal transplantation that negatively impacts early and late allograft function. Follistatin (FS) is a protein that binds activin and inhibits its activity. This study examined the response of activin A and ...
T cells have been implicated in the early pathogenesis of ischemia reperfusion injury (IRI) of kidney, liver, lung, and brain. It is not known whether Ag-TCR engagement followed by Ag-specific T cell activation participates in IRI. T cell-deficient nu/nu mice are moderately resistant to renal IRI, which can be reversed upon reconstitution with syngeneic T cells. In this study, we found that nu/...
background renal ischemia reperfusion (ir) contributes to the development of acute renal failure (arf). oxygen free radicals are considered principal components involved in the pathophysiological tissue alterations observed during renal ir. objective in this study, we compared the effects of melatonin (mel) and erythropoietin (epo), which are known antioxidant and anti-inflammatory agents, in i...
objective(s): some histopathological alterations take place in the ischemic regions following brain ischemia. recent studies have demonstrated some neuroprotective roles of crocin in different models of experimental cerebral ischemia. here, we investigated the probable neuroprotective effects of crocin on the brain infarction and histopathological changes after transient model of focal cerebral...
