Lipopolysaccharides or endotoxins elicit an excessive host inflammatory response and lead to life-threatening conditions such as endotoxemia and septic shock. Lipopolysaccharides trigger mobilization and stimulation of leukocytes and exaggerated production of pro-inflammatory molecules including cytokines and proteolytic enzymes. Matrix metalloproteinase-9 (MMP-9) or gelatinase B, a protease st...
Shenkar, Robert, Ho-Kee Yum, John Arcaroli, John Kupfner, and Edward Abraham. Interactions between CBP, NF-kB, and CREB in the lungs after hemorrhage and endotoxemia. Am J Physiol Lung Cell Mol Physiol 281: L418–L426, 2001.—The transcriptional regulatory factor nuclear factor (NF)-kB has a central role in modulating expression of proinflammatory mediators that are important in acute lung injury...
BACKGROUND Reduced erythrocyte survival and deformability may contribute to the so-called anemia of inflammation observed in septic patients. Erythrocyte structure and function are affected by both the membrane lipid composition and the organization. We therefore aimed to determine whether these parameters are affected during systemic inflammation. METHODS A sensitive matrix-assisted laser de...
BACKGROUND Excessive continuous NO release from inducible NO synthase over prolonged periods under pathological conditions, such as endotoxemia, contributes significantly to circulatory failure, hypotension, and septic shock. This NO production during endotoxemia is accompanied by superoxide release, which contributes to the fast decay of NO. Therefore, the amount of NO that diffuses to target ...
Background: Limited data exist regarding systemic inflammation and endotoxemia in different circulatory compartments patients with acute variceal bleeding (AVB). Further, the correlation of these abnormalities hepatic venous pressure gradient (HVPG) AVB remain unexplored. Aim: To assess milieu peripheral blood regard to evaluated their HVPG AVB. Methods: In this prospective pilot study, serum i...
Diabetes and obesity are two metabolic diseases characterized by insulin resistance and a low-grade inflammation. Seeking an inflammatory factor causative of the onset of insulin resistance, obesity, and diabetes, we have identified bacterial lipopolysaccharide (LPS) as a triggering factor. We found that normal endotoxemia increased or decreased during the fed or fasted state, respectively, on ...
Endotoxin-related acute kidney injury has been shown to profoundly induce nitric oxide (NO), which activates sympathetic and renin-angiotensin system, resulting in renal vasoconstriction. While vascular muscle cells are known to upregulate inducible NO synthase (iNOS), less is known about the endothelium as a source of NO during endotoxemia. Studies were, therefore, undertaken both in vitro in ...
AIM AQP4 in the brain is involved in the occurrence and development of a variety of encephalopathy. AQPs family changes in kidney were accompanied by altered UTs family. The aim of this study was to observe AQP4 and UT-A3 expression in CNS and to explore their role in the pathogenesis of endotoxemia encephalopathy following peripheral LPS injection in mice. METHODS Endotoxemia was induced in ...
The effect of sustained endotoxemia on expression of the acid-labile subunit (ALS) in relation to hepatic markers of altered GH and insulin sensitivity was examined. Juvenile rats were injected with endotoxin twice daily for 48 h, causing reduced food intake and attenuated growth. In pair-fed controls, food restriction caused marked suppression of ALS gene expression and circulating levels with...
Proprotein convertase subtilisin/kexin type 9 (PCSK9) is a secreted protein that targets LDL receptors (LDLRs) for degradation in liver. Blocking the interaction of PCSK9 with the LDLR potently reduces plasma LDL cholesterol levels and cardiovascular events. Recently, it has been suggested that inhibition of PCSK9 might also improve outcomes in mice and humans with sepsis, possibly by increasin...
