BACKGROUND: Morbid obesity is related to chronic inflammation and many metabolic complications. Interleukin (IL)-6 plays a pivotal pathophysiological role in obesity, and IL-6 trans-signaling through the soluble IL-6 receptor (sIL-6R) has a major proinflammatory effect. The aim of this study was to investigate the association between sIL-6R, adipocyte size, and insulin resistance in morbidly obese individuals. METHODS: We measured concentrations of sIL-6R, high-sensitivity C-reactive protein, and lipid parameters and estimated homeostasis model assessment of insulin resistance (HOMA-IR) before the patients underwent bariatric surgery...

Obesity is associated with metabolic inflammation and endoplasmic reticulum (ER) stress, both of which promote metabolic disease progression. Adipose tissue macrophages (ATMs) are key players orchestrating metabolic inflammation, and ER stress enhances macrophage activation. However, whether ER stress pathways underlie ATM regulation of energy homeostasis remains unclear. Here, we identified inositol-requiring enzyme 1α (IRE1α) as a critical switch governing M1-M2 macrophage polarization and energy balance...

Aging and overnutrition cause obesity in rodents and humans. It is well-known that obesity causes various diseases by producing insulin resistance (IR). Macrophages infiltrate the adipose tissue (AT) of obese individuals and cause chronic low-level inflammation associated with IR. Macrophage infiltration is regulated by the chemokines that are released from hypertrophied adipocytes and the immune cells in AT. Saturated fatty acids are recognized by toll-like receptor 4 (TLR4) and induce inflammatory responses in AT macrophages (ATMs)...

Adipose-derived stem cells (ADSCs) were previously considered to have an anti-inflammatory effect, and Interleukin-1beta (IL-1beta) was found to be a pro-inflammatory factor in chondrocytes, but the mechanism underlying ADSCs and IL-1beta is unclear. In this study, we investigate whether P2X7 receptor (P2X7R) signalling, regulated by microRNA 373 (miR-373), was involved in the ADSCs and IL-1beta mediated inflammation in osteoarthritis (OA). Chondrocytes were collected from 20OA patients and 20 control participants, and ADSCs were collected from patients who had undergone abdominal surgery...

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: 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...

BACKGROUND Mesenchymal stromal cells (MSCs) possess potent immunomodulatory properties that increase their value as a cell-based therapeutic tool for managing various immune-based disorders. Over the past years, accumulated results from trials using MSCs-based therapy have shown substantial contradictions. Although the reasons underlying these discrepancies are still not completely understood, it is well known that the immunomodulatory activities mediated by distinct MSCs differ in a manner dependent on their tissue origin and adequate response to inflammation priming...

OBJECTIVE: The function of perivascular adipose tissue as an anticontractile mediator in the microvasculature is lost during obesity. Obesity results in inflammation and recruitment of proinflammatory macrophages to the perivascular adipose tissue that is paralleled by depletion of the vasorelaxant signaling molecule hydrogen sulfide (H2S) in the vessel. The current objective was to assess the role of macrophages in determining vascular [H2S] and defining how this impinged on vasodilation...

Neuronatin (NNAT) is known to regulate ion channels during brain development and plays a role in maintaining the structure of the nervous system. A previous in silico analysis showed that Nnat was overexpressed in the adipose tissue of an obese rodent model relative to the wild-type. Therefore, the aim of the present study was to investigate the function of Nnat in the adipose tissue. Because obesity is known to systemically induce low-grade inflammation, the Nnat expression level was examined in the adipose tissue obtained from C57BL/6 mice administered lipopolysaccharide (LPS)...

Metabolic disorder has been frequently observed in chronic obstructive pulmonary disease (COPD) patients. However, the exact correlation between obesity, which is a complex metabolic disorder, and COPD remains controversial. The current study summarizes a variety of drugs from marine sources that have anti-obesity effects and proposed potential mechanisms by which lung function can be modulated with the anti-obesity activity. Considering the similar mechanism, such as inflammation, shared between obesity and COPD, the study suggests that marine derivatives that act on the adipose tissues to reduce inflammation may provide beneficial therapeutic effects in COPD subjects with high body mass index (BMI)...

BACKGROUND: Mesenchymal stromal/stem cell (MSC) transplantation is a promising therapy for tissue regeneration. Extracellular vesicles (EVs) released by MSCs act as their paracrine effectors by delivering proteins and genetic material to recipient cells. To assess how their cargo mediates biological processes that drive their therapeutic effects, we integrated miRNA, mRNA, and protein expression data of EVs from porcine adipose tissue-derived MSCs. METHODS: Simultaneous expression profiles of miRNAs, mRNAs, and proteins were obtained by high-throughput sequencing and LC-MS/MS proteomic analysis in porcine MSCs and their daughter EVs (n = 3 each)...

Diabetic peripheral neuropathy (DPN) and diabetic kidney disease (DKD) are common diabetic complications with limited treatment options. Experimental studies show that targeting inflammation using chemokine receptor (CCR) antagonists ameliorates DKD, presumably by reducing macrophage accumulation or activation. As inflammation is implicated in DPN development, we assessed whether CCR2 and CCR5 antagonism could also benefit DPN. Five-week-old ob/ob mice were fed a diet containing MK-0812, a dual CCR2-CCR5 receptor antagonist, for 8 weeks and DPN, DKD, and metabolic phenotyping were then performed to determine the effect of CCR inhibition...

Adipokines, including adiponectin and resistin, are cytokines produced mainly by adipose tissue. They play a significant role in the metabolic functions that regulate insulin sensitivity and inflammation. Alteration of adiponectin and resistin plasma levels, or their expression in metabolic and gonadal tissue, are observed in some metabolic pathologies, such as obesity. Several studies have shown that these two hormones and the receptors for adiponectin, AdipoR1 and AdipoR2, are present in various reproductive tissues in both sexes of different species...

Study Objectives: Increased visceral white adipose tissue (vWAT) mass results in infiltration of inflammatory macrophages that drive inflammation and insulin resistance. Patients with obstructive sleep apnea (OSA) suffer from increased prevalence of obesity, insulin resistance and metabolic syndrome. Murine models of intermittent hypoxia (IH) mimicking moderate-severe OSA manifest insulin resistance following short-term IH. We examined in mice the effect of long-term IH on the inflammatory cellular changes within vWAT, and the potential effect of normoxic recovery (IH-R)...

BACKGROUND: Obese individuals differ in their risk of developing metabolic and cardiovascular complications depending on fat distribution (subcutaneous versus visceral) and adipose tissue (AT) phenotype (hyperplasic versus hypertrophic). However, the exact mechanisms which determine whether an obese individual is metabolically healthy or unhealthy are not clear, and analyses of the underlying pathomechanisms are limited by the lack of suitable in vivo models in which metabolically healthy versus metabolically unhealthy AT accumulation can be specifically induced...

Cardiovascular disease (CVD) is a major cause of morbidity and mortality worldwide. Inflammatory processes arising from metabolic abnormalities are known to precipitate the development of CVD. Several metabolic and inflammatory markers have been proposed for predicting the progression of CVD, including high density lipoprotein cholesterol (HDL-C). For ~50 years, HDL-C has been considered as the atheroprotective 'good' cholesterol because of its strong inverse association with the progression of CVD. Thus, interventions to increase the concentration of HDL-C have been successfully tested in animals; however, clinical trials were unable to confirm the cardiovascular benefits of pharmaceutical interventions aimed at increasing HDL-C levels...

Alzheimer's disease (AD), characterized by the abnormal accumulation of amyloid beta (Aβ), is gradually increasing globally. Given that AD is considered a neuroinflammatory disease, recent studies have focused on the cellular mechanisms in brain inflammatory conditions that underlie AD neuropathology. Microglia are macrophage cells in the central nervous system (CNS) that are activated in response to Aβ condition. The function of microglia contributes to the neuroinflammation in AD brain, suggesting that microglia regulate the production of inflammatory mediators and contribute to the regeneration of damaged tissues...

Chronic exposure to diets high in saturated fat (HFD) increases the prevalence of obesity and contributes to the development of low-grade inflammation and insulin resistance. A possible mediator accounting for obesity-associated inflammation and insulin resistance is Toll-like receptor 4 (TLR4). We investigated the role of adipocyte TLR4 in lipid and glucose homeostasis through an inducible, adipocyte-specific deletion of TLR4, the "TADIPO mouse". Consistent with a critical role for inflammation as a positive force for healthy adipose tissue expansion, chronic HFD exposure resulted in exacerbated whole body and muscle insulin resistance in the absence of TLR4 in the adipocyte...

It has been shown that serum homocycteine (Hcy) levels are higher in women with polycystic ovary syndrome (PCOS). However, the specific role of hyperhomocycteinemia (HHcy) in the development of PCOS has never been reported. Adipose tissue inflammation is featured by the infiltration of macrophages that plays a critical role in the pathogenesis of glucose and insulin intolerance. In this study, C57BL/6 mice were treated with dehydroepiandrosterone (DHEA) and/or high methionine diet to induce PCOS and HHcy mice models...
