BACKGROUND Hydrogen sulfide (H2S), produced by the activity of cystathionine-gamma-lyase (CSE), is a key mediator of inflammation in sepsis. The liver sinusoidal endothelial cells (LSECs) are important target and mediator of sepsis. The aim of this study was to investigate the role of CSE-derived H2S on inflammation and LSECs fenestrae in caecal-ligation(More)
The renin-angiotensin system (RAS) conceived as a coordinated hormonal cascade plays an important role in controlling multiple functions in many organs and is much more complex than previously thought. The RAS has continued to expand, with the identification of new components, functions and subsystems. Angiotensin-converting enzyme (ACE) and its novel(More)
Hydrogen sulphide is an endogenous inflammatory mediator produced by cystathionine-γ-lyase (CSE) in macrophages. To determine the role of H2S and macrophages in sepsis, we used small interference RNA (siRNA) to target the CSE gene and investigated its effect in a mouse model of sepsis. Cecal ligation puncture (CLP)-induced sepsis is characterized by(More)
Hydrogen sulphide (H2S) is an endogenous inflammatory mediator produced by cystathionine-γ-lyase (CSE) in monocytes/macrophages. To determine the role of H2S and macrophages in inflammation, we used small interference RNA (siRNA) to target the CSE gene and investigated its effect in a mouse model of acute pancreatitis. Acute pancreatitis is characterised by(More)
Sepsis remains a common clinical problem with significant mortality. Activation of the Kupffer cells during sepsis is associated with systemic inflammatory response and multiple organ failure. Kupffer cell activation also leads to structural changes in the liver sinusoidal endothelial cells (LSECs) during endotoxemia. However, these effects remain to be(More)
BACKGROUND The objective of this study was to determine if RAS bioactive enzymes and peptides are perturbed in acute pancreatitis and associated lung injury. METHODS The intervention group of mice were treated with ten hourly intraperitoneal (i.p.) injections of caerulein (50 μg/kg) to induce acute pancreatitis. Animals were euthanized, samples of(More)
