Sepsis affects millions of people worldwide and is associated with acute kidney injury (AKI). Innate and adaptive immune cells have been shown to play an important role in AKI through release of various inflammatory mediators which include reactive oxidant species (ROS). Acetate, a short chain fatty acid produced by gut bacteria has anti-inflammatory properties and has also been shown to modulate oxidative stress in different immune cells. Effects of acetate have been shown to be both GPR43 dependent and independent in different cells/tissues...

Both NF-κB pathway and complement activation appear to be involved in kidney damage induced by trichloroethylene (TCE). However, any relationship between these two systems has not yet been established. The present study aimed to clarify the role of NF-κB in complement activation and renal injury in TCE-sensitized BALB/c mice. Mice were sensitized by an initial subcutaneous injection and repeated focal applications of TCE to dorsal skin at specified timepoints. NF-κB inhibitor pyrrolidine dithiocarbamate (PDTC) was injected (intraperitoneal) before the final two focal TCE challenges...

Cyclophosphamide (CY) is a widely used chemotherapeutic agent that is associated with severe side effects, such as hepatotoxicity and nephrotoxicity. However, the extent, mechanisms and potential prevention and treatment strategies of CY-induced acute hepatotoxicity and nephrotoxicity are largely unknown. In this study, we determined the existence and extent of CY-induced acute hepatotoxicity and nephrotoxicity, and demonstrated the effect of ALDH2 on CY-induced acute tissue toxicity and related mechanisms...

BACKGROUND: Lassa fever is a viral haemorrhagic disease endemic to west Africa. No large-scale studies exist from Nigeria, where the Lassa virus (LASV) is most diverse. LASV diversity, coupled with host genetic and environmental factors, might cause differences in disease pathophysiology. Small-scale studies in Nigeria suggest that acute kidney injury is an important clinical feature and might be a determinant of survival. We aimed to establish the demographic, clinical, and laboratory factors associated with mortality in Nigerian patients with Lassa fever, and hypothesised that LASV was the direct cause of intrinsic renal damage for a subset of the patients with Lassa fever...

Zhen-wu-tang (ZWT) has been widely applied in chronic kidney diseases. However, the mechanism of ZWT remains unclear. Peroxisome proliferator-activated receptors-γ (PPARγ) is known as a protective factor for podocyte and kidney function. This study is aimed to investigate the protective effects of ZWT on IgA nephropathy (IgAN) in rats against podocyte injury and the underlying mechanism related to PPARγ. IgAN model rats were induced by administering bovine serum albumin, lipopolysaccharide, and carbon tetrachloride...

BACKGROUND: Cirrhosis of the liver is often associated with an impairment of renal function that is usually not associated with consistent structural abnormalities of the renal parenchyma, but is thought to be the functional consequence of arterial underfilling and reduced arterial blood pressure. METHOD: We have used the cirrhosis model of chronic bile duct ligation (BDL) to assess the response of renal blood flow to a change of blood pressure. We have measured renal haemodynamics in BDL rats...

BACKGROUND: The cytokine interleukin-18 was originally identified as an interferon-γ-inducing proinflammatory factor; however, there is increasing evidence to suggest that it has non-immunological effects on physiological functions. We previously investigated the potential pathophysiological relationship between interleukin-18 and dyslipidemia, non-alcoholic fatty liver disease, and non-alcoholic steatohepatitis, and suggested interleukin-18 as a possible novel treatment for not only these diseases but also for cancer immunotherapy...
