Alzheimer's disease (AD) is a progressive neurodegenerative disorder, accompanied by memory loss and cognitive impairments, and there is no effective treatment for it at present. Since type 2 diabetes (T2DM) has been identified as a risk factor for AD, the incretins glucagon-like peptide 1 (GLP-1) and glucose dependent insulinotropic polypeptide (GIP), promising antidiabetic agents for the treatment of type 2 diabetes, have been tested in models of neurodegenerative disease including AD and achieved good results...

White adipose tissue plays an important endocrine role in balancing metabolic homeostasis. During conditions of nutrient excess, as occurs in obesity, there is an expansion of adipose tissue mass that triggers a state of "low-grade" inflammation in this tissue. This chronic, unresolved inflammation of adipose tissue is deleterious and leads to many pathological sequelae associated with obesity including insulin resistance, type 2 diabetes and non-alcoholic fatty liver disease. Recently, a novel genus of anti-inflammatory and pro-resolving lipid mediators endogenously generated from membrane phospholipid-derived polyunsaturated fatty acids has been identified during the resolution phase of acute inflammation...

BACKGROUND & AIMS: Iron overload disorders such as hereditary hemochromatosis and iron-loading anemias are a common cause of morbidity from liver diseases and increase risk of hepatic fibrosis and hepatocellular carcinoma (HCC). Once iron-induced damage occurs, treatment options are limited partly because of the lack of animal models recapitulating human disease, which do not exhibit relevant sequelae after chronic iron overload. METHODS: Since liver-specific β-catenin knockout mice (KO) are susceptible to injury, fibrosis and tumorigenesis following chemical carcinogen exposure, iron-overload diet was administered to KO and littermate control (CON) mice for various times...

The global burden of kidney disease is increasing strikingly in parallel with increases in obesity and diabetes. Indeed, chronic kidney disease (CKD) and end-stage renal disease (ESRD) coupled with comorbidities such as obesity, diabetes, and hypertension cost the health care system hundreds of billions of dollars in the US alone. The progression to ESRD in patients with obesity and diabetes continues despite widespread use of inhibitors of the renin-angiotensin-aldosterone system (RAAS) along with aggressive blood pressure and glycemic control in these high-risk populations...

BACKGROUND: Hepatitis C virus (HCV) infection is the major cause of hepatocellular carcinoma (HCC), a common primary liver malignancy, and the third leading cause of cancer-related death. The HCC risk increases with the severity of liver inflammation, and the clinical course of HCV infection depends on a balance between pro- and anti-inflammatory cytokines. The former includes interleukin (IL)-6, while the latter includes IL-10. However, the exact pathogenic mechanisms underlying IL-6 and IL-10 effects remain unclear...

OBJECTIVES: Several studies reported that antidepressant drugs have immune-regulatory effects by acting on specific inflammatory mediators. However, considering the highly complex nature of the inflammatory response, we have adopted an unbiased genome-wide strategy to investigate the immune-regulatory activity of the antidepressant agomelatine in modulating the response to an acute inflammatory challenge. METHODS: Microarray analysis was used to identify genes modulated in the ventral hippocampus of adult rats chronically treated with agomelatine (40 mg/kg, os) before being challenged with a single injection of lipopolysaccharide (LPS; 250 μg/kg, i...

Chronic inflammation significantly contributes to the pathogenesis of several neurodegenerative disorders. In physiological conditions, a chronic inflammatory state is prevented through the termination of the acute inflammatory response once the triggering insult is eliminated. Several mechanisms regulate the resolution of inflammation. Among these, a potent inhibitor of the pro-inflammatory NF-kB signaling known as A20 has emerged as a key player. Recent studies have shown reduced blood levels of A20 in the patients of diverse chronic inflammatory diseases...

This study tested the hypothesis that combined therapy with melatonin (Mel) and exendin-4 (Ex4) would be superior to either therapy alone for preventing the deterioration of renal function in cardiorenal syndrome (CRS). Male adult Sprague Dawley rats (n = 48) were randomly and equally divided into sham-control (SC), chronic kidney disease (CKD; induced by 5/6 nephrectomy), CRS (CKD + dilated cardiomyopathy, DCM; induced by doxorubicin 7 mg/kg i.p. every 5 days, 4 doses), CRS-Mel (20 mg/kg/day), CRS-Ex4 (10 µg/kg/day) and CRS-Mel-Ex4...

BACKGROUND: Overweight and obesity is a growing health problem worldwide. The most effective strategy to reduce weight is energy restriction (ER). ER has been shown to be beneficial in disease prevention and it reduces chronic inflammation. Recent studies suggest that reducing the protein quantity of a diet contributes to the beneficial effects by ER. The organ most extensively affected during ER is white adipose tissue (WAT). OBJECTIVE: The first objective was to assess changes in gene expression between a high protein diet and a normal protein diet during ER...

Catechins are natural polyphenolic phytochemicals that exist in food and medicinal plants, such as tea, legume and rubiaceae. An increasing number of studies have associated the intake of catechins-rich foods with the prevention and treatment of chronic diseases in humans, such as inflammatory bowel disease (IBD). Some studies have demonstrated that catechins could significantly inhibit the excessive oxidative stress through direct or indirect antioxidant effects and promote the activation of the antioxidative substances such as glutathione peroxidases (GPO) and glutathione (GSH), reducing the oxidative damages to the colon...

Radix salviae miltiorrhizae (Danshen in Chinese), a classic traditional Chinese medicine (TCM) herb, has been used for centuries to treat liver diseases. In this study, the preventive and curative potential of Danshen aqueous extract on acute/chronic alcoholic liver disease (ALD) and non-alcoholic fatty liver disease (NAFLD) was studied. The in vivo results indicated that Danshen could alleviate hepatic inflammation, fatty degeneration, and haptic fibrogenesis in ALD and NAFLD models. In the aspect of mechanism of action, the significant reduction in MDA levels in both ALD and NAFLD models implies the decreased levels of oxidative stress by Danshen...

PROBLEM: Expression of CD200 at the feto-maternal interface is associated with successful murine and human pregnancy. CD200 binding to CD200 receptors on lymphomyeloid cells suppresses inflammation and induces Tregs. CD200 receptors are also expressed on mouse and human placental trophoblast cells. What is the expression of CD200 and CD200R in human missed abortions which have preserved Treg levels and in chronic histiocytic intervillositis (CHI) where maternal inflammatory cells cause IUGR? METHODS: Immunohistiochemistry for CD200, CD200R, and Ki67 using human placental sections from missed abortions, term placenta, and CHI...

Mucosal surfaces account for the vast majority of HIV transmission. In adults, HIV transmission occurs mainly by vaginal and rectal routes but rarely via oral route. By contrast, pediatric HIV infections could be as the result of oral route by breastfeeding. As such mucosal surfaces play a crucial role in HIV acquisition, and spread of the virus depends on its ability to cross a mucosal barrier. HIV selectively infects, depletes, and/or dysregulates multiple arms of the human immune system particularly at the mucosal sites and causes substantial irreversible damage to the mucosal barriers...

Chronic, low-grade systemic inflammation and impaired microvascular function are critical hallmarks in the development of insulin resistance. Accordingly, insulin resistance is a major risk factor for type 2 diabetes and cardiovascular disease. Accumulating studies demonstrate that restoration of impaired function of the diabetic macro- and microvasculature may ameliorate a range of cardiovascular disease states and diabetes-associated complications. In this review, we focus on the emerging role of microRNAs, non-coding RNAs that fine-tune target gene expression and signaling pathways, in insulin-responsive tissues and cell types important for maintaining optimal vascular homeostasis and preventing the sequelae of diabetes-induced end organ injury...

Oxidative stress aggravates renal fibrosis, a pathway involved in almost all forms of chronic kidney disease (CKD). However, the underlying mechanism involved in the pathogenesis of renal oxidative stress has not been completely elucidated. In this study, we explored the role and mechanism of hypochlorite-modified albumin (HOCl-alb) in mediating oxidative stress and fibrotic response in a remnant-kidney rat model. Five-sixths nephrectomy (5/6 NX) was performed on the rats and then the animals were randomly assigned to intravenous treatment with either vehicle alone, or HOCl-rat serum albumin (RSA) in the presence or absence of SS-31 (administered intraperitoneally)...

Growing evidence indicates that angiotensin II (Ang II), a potent biologically active product of RAS, is a key regulator of renal inflammation and fibrosis. In this study, we tested the hypothesis that Ang II induces renal inflammatory injury and fibrosis through interaction with myeloid differentiation protein-2 (MD2), the accessory protein of toll-like receptor 4 (TLR4) of the immune system. Results indicated that in MD2(-/-) mice, the Ang II-induced renal fibrosis, inflammation and kidney dysfunction were significantly reduced compared to control Ang II-infused wild-type mice...

An understanding of the mechanisms underlying diseases is critical for their prevention. Excessive exposure to crystalline silica is a risk factor for silicosis, a potentially fatal pulmonary disease. Male Fischer 344 rats were exposed by inhalation to crystalline silica (15 mg/m(3), six hours/day, five days) and pulmonary response was determined at 44 weeks following termination of silica exposure. Additionally, global gene expression profiling in lungs and BAL cells and bioinformatic analysis of the gene expression data were done to understand the molecular mechanisms underlying the progression of pulmonary response to silica...

Alzheimer's disease (AD) is the most common form of dementia diagnosed amongst the elderly. Mild cognitive impairment (MCI) is a condition often indicative of the earliest symptomatology of AD with 10%-15% of MCI patients reportedly progressing to a diagnosis of AD. Individuals with a history of vascular risk factors (VRF's) are considered high risk candidates for developing cognitive impairment in later life. Evidence suggests that vascular injury resulting from untreated VRF's promotes progression from MCI to AD and exacerbates the severity of dementia in AD, and neuroimaging studies have found that the neurodegenerative processes associated with AD are heavily driven by VRF's that promote cerebral hypoperfusion...
