Endothelial dysfunction precedes atherosclerosis and may constitute a critical link between obesity-related inflammation and cardiovascular disease. Neutrophil extracellular traps (NETs) have been shown to promote vascular damage in murine models of autoimmune disease and atherosclerosis. The impact of NETs towards endothelial dysfunction associated with obesity is unknown. Using a diet-induced obesity (DIO) mouse model, this study investigated whether the inhibition or degradation of NETs could reduce the endothelial dysfunction observed in DIO mice...

BACKGROUND: Nephropathy is a debilitating complication of diabetes associated with increased risk for renal failure, leading to poor quality of life of the affected patients and eventually to mortality. Early intervention is crucial to enhance the well-being of the patients with nephropathy. Albuminuria is a well-known predictor of weak renal outcomes in patients with diabetes and hypertension, unfortunately, it is not an early marker for kidney injury. OBJECTIVE: Assessment of new and precise markers is necessary to predict the early onset and progression of nephropathy...

Diabetic nephropathy (DN) is the major cause of end-stage renal disease in diabetic patients. Zicao, a well-known Chinese traditional medicine, has attracted much attention due to its beneficial effects in various medical fields. In this study, we attempted to investigate the effects and mechanisms of action of acetylshikonin, the main ingredient of Zicao, on renal dysfunction in DN. Our results showed that administration with acetylshikonin not only decreased blood urea nitrogen, urine creatinine and the mean kidney-to-body weight ratio in streptozotocin-induced diabetic mice, but also restored the loss of body weight, whereas the blood glucose was not changed...

Type-I interferons (IFN-I) are widely used for antiviral immunotherapy in clinic. Therefore, identification of the regulators of IFN-I antiviral activity is important for developing novel targets for IFN-based antiviral therapy. Monocyte chemoattractant protein 1-induced protein 1 (MCPIP1) is critical for cellular inflammatory responses. However, the roles of MCPIP1 in interferons (IFNs)-mediated antiviral immunity are unexplored. In this study, we demonstrate for the first time that MCPIP1 is an important positive regulator of IFNs antiviral activity...

Although paclitaxel effectively treats various cancers, its debilitating peripheral neuropathic pain side effects often persist long after treatment has ended. Therefore, a compelling need exists for the identification of novel pharmacologic strategies to mitigate this condition. As inhibitors of monoacylglycerol lipase (MAGL), the primary hydrolytic enzyme of the endogenous cannabinoid 2-arachidonyolglycerol, produce antinociceptive effects in numerous rodent models of pain, we investigated whether inhibitors of this enzyme (i...

Many inflammatory cells are known to home to inflamed temporomandibular joint (TMJ) tissues by stimulation with cytokines and chemokines produced by inflammatory lesions in the TMJ. However, how the inflammatory cells affect the progression of inflammation in TMJ synovial tissues after their homing to inflamed TMJ site is still uncertain. Here, we isolated and cultured TMJ synoviocyte-like cells (TMJSCs) from murine TMJ tissues. We demonstrated that interleukin 1b (IL-1β) upregulated expression of monocyte chemoattractant protein 1 (MCP-1) in TMJSCs...

Obesity is a major risk factor for insulin resistance and type 2 diabetes. In adipose tissue, obesity-mediated insulin resistance correlates with the accumulation of proinflammatory macrophages and inflammation. However, the causal relationship of these events is unclear. Here, we report that obesity-induced insulin resistance in mice precedes macrophage accumulation and inflammation in adipose tissue. Using a mouse model that combines genetically induced, adipose-specific insulin resistance (mTORC2-knockout) and diet-induced obesity, we found that insulin resistance causes local accumulation of proinflammatory macrophages...

Chronic liver disease per se induces neuroinflammation that contributes to cognitive deficits in hepatic encephalopathy (HE). However, the processes by which pro-inflammatory molecules result in cognitive impairment still remain unclear. In the present study, a significant increase in the activity of liver function enzymes viz. alanine transaminase (ALT), aspartate transaminase (AST) and alkaline phosphatase (ALP) was observed along with increase in plasma ammonia levels after four weeks of bile duct ligation (BDL) in rats suggesting hepatocellular damage...

BACKGROUND: We previously reported that children undergoing cardiac surgery are at high risk for long-term chronic kidney disease (CKD) and hypertension, although postoperative acute kidney injury (AKI) is not a risk factor for worse long-term kidney outcomes. We report here our evaluation of renal injury biomarkers 5 years after cardiac surgery to determine whether they are associated with postoperative AKI or long-term CKD and hypertension. METHODS: Children aged 1 month to 18 years old undergoing cardiopulmonary bypass were recruited to this prospective cohort study...

We present an atomistic level computational investigation of the dynamics of a signaling protein, Monocyte Chemoattractant Protein-1 (MCP-1), that explores how simulation geometry and solution ionic strength affect the calculated diffusion coefficient. Using a simple extension of non-cubic finite size diffusion correction expressions, it is possible to calculate experimentally comparable diffusion coefficients that are fully consistent with those determined from cubic box simulations. Additionally, increasing the concentration of salt in the solvent environment leads to changes in protein dynamics that are not explainable through changes in solvent viscosity alone...
