Mammalian target of rapamycin (mTOR), a serine/threonine kinase plays an important role in various pathophysiological processes including cancer, metabolic diseases, and inflammation. Although mTOR participates in Toll-like receptor 4 signalling in different cell types, the role of this enzyme in sepsis pathogenesis and its effects on hypotension and inflammation in endotoxemic rats remains unclear. In this study we investigated the effects of mTOR inhibition on lipopolysaccharide (LPS)-induced changes on expressions and/or activities of ribosomal protein S6 (rpS6), an mTOR substrate, nuclear factor-κB (NF-κB) p65, inhibitor κB (IκB)-α, inducible nitric oxide synthase (iNOS), cyclooxygenase (COX)-2 with production of nitric oxide, peroxynitrite, prostacyclin, and tumor necrosis factor (TNF)-α and activity of myeloperoxidase (MPO), which results in hypotension and inflammation...

Despite advances in cancer treatment, metastasis remains today the main cause of cancer death. Local control through complete surgical resection of the primary tumor continues to be a key principle in cancer treatment. However, surgical interventions themselves lead to adverse oncologic outcomes and are associated with significantly increased rates of metastasis. Neutrophils through release of neutrophil extracellular traps (NETs) in response to infections were shown to be able to capture circulating cancer cells, and in doing so, support the development of metastatic disease...

Sepsis, characterized by systemic inflammation, often leads to end-organ dysfunction, such as acute kidney injury (AKI). Despite of the severity and frequency of septic AKI in clinic, its pathogenesis is still poorly understood. Combined with histopathology evaluations, mortality assessments, biochemical evaluations, reverse transcription (RT) reaction and quantitative real-time PCR, and western blot, (1)H NMR-based metabolomics approach was applied to investigate effects of Huang-Lian-Jie-Du-Decotion (HLJDD), a traditional Chinese medicine prescription, and its four component herbs on lipopolysaccharide (LPS)-induced septic AKI and the underlying mechanism...

Heparanase, a heparan sulfate (HS)-specific endoglycosidase, plays an important role in inflammation and mediates acute pulmonary and renal injuries during sepsis. To explore its role in septic intestinal injury, a non-anticoagulant heparanase inhibitor, N-desulfated/re- N-acetylated heparin (NAH), was administrated to a mouse sepsis model induced by cecal ligation and puncture (CLP). Immunohistochemical staining revealed massive shedding of HS from the intestinal mucosal surfaces after CLP, and effective inhibition of heparanase by NAH was confirmed by markedly reduced HS shedding...

BACKGROUND: Sepsis is characterized by an early systemic inflammation in response to infection. In the brain, inflammation is associated with expression of pro-inflammatory cytokines (e.g. tumor necrosis factor-α, interleukin-1β and interleukin-6, among others) that may induce an overproduction of reactive oxygen and nitrogen species. The constitutive expression of cytokines in the brain is low, but may be induced by various stimuli, including lipopolysaccharide, which causes neuronal damage...

INTRODUCTION: Leptin is thought to play an important role in the regulation of the immune system. In patients, leptin is inversely proportional to interleukin-6 (IL-6) levels. Thus, the objective of our study was to evaluate a dose-dependent therapeutic impact of leptin with possible IL-6-dependency on immune actions and outcome in a trauma/sepsis model. MATERIALS AND METHODS: Sixty-nine wild-type and 63 IL-6 mice were subdivided into three groups: trauma/sepsis group (first hit: femur fracture and hemorrhage; second hit: cecal ligation and puncture 2 days later), trauma group (first hit and laparotomy), sham group (laparotomy only)...
