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...

Obesity is characterized by chronic low-grade inflammation driven by activation and tissue infiltration of circulating leukocytes. Although exercise has anti-inflammatory effects, the impact of exercise on mediators of leukocyte migration is unclear. PURPOSE: To determine the impact of high intensity interval training (HIIT) versus moderate intensity continuous training (MICT), in the absence of weight/fat loss, on circulating chemokines and leukocyte chemokine receptors. METHODS: Thirty-seven inactive obese adults were randomized to two weeks (10 sessions) of HIIT or MICT with fasting blood samples collected before and after training...

REVIEW
Owein Guillemot-Legris, Giulio G Muccioli
Obesity is now a worldwide health issue. Far from being limited to weight gain, obesity is generally associated with low-grade inflammation and with a cluster of disorders collectively known as the 'metabolic syndrome'. When considering obesity and the subsequent neuroinflammation, the focus was long set on the hypothalamus. More recently, obesity-derived neuroinflammation has been shown to affect other brain structures such as the hippocampus, cortex, brainstem, or amygdala. Furthermore, obesity has been associated with increased occurrence of central disorders such as depression and impaired cognitive function...

Sarcopenia is a major determinant of frailty, disability and mortality in the elderly. Whether low-grade inflammation, insulin resistance and vitamin D are independently associated with sarcopenia remains unclear. In our study, sarcopenia was defined as an appendicular skeletal muscle mass divided by height squared (ASM/Ht(2)) that was <2 SD below the normal means for young adults. Insulin resistance was estimated using the homeostasis model assessment of insulin resistance (HOMA-IR) index [(insulin (IU/mL) × fasting glucose (mg/dL)/18)/22...

Statins are used widely in primary and secondary prevention of cardiovascular disease; a treatment effect that has long been thought to be due to their cholesterol-lowering properties. However, statins also have a wide range of anti-inflammatory effects independent of their lipid-lowering mechanisms. In depression, low-grade inflammation is a replicated finding, and several studies have shown antidepressant properties of diverse anti-inflammatory drugs. Large observational studies have suggested reduced risks of depression amongst those taking statins, an effect that is thought to be explained by the anti-inflammatory properties of this class of drugs...

Abnormal lipid-mediated hepatic inflammatory-immune dysfunction and chronic low grade inflammation play an important role in the pathogenesis of non-alcoholic fatty liver disease (NAFLD). Macrophage polarization is an important mechanism for the regulation of inflammatory response. Since PPAR-γ has emerged as a master regulator of macrophage polarization, we aimed to investigate the lipid-induced macrophage/Kupffer cell polarization in vivo and in vitro, and explore the association between PPAR-γ activity and macrophages M1/M2 polarization shifting...

Hyun Lim, Byung Kyu Park, Sook Young Shin, Yong Soo Kwon, Hyun Pyo Kim
During aging, cells secrete molecules called senescence-associated secretory phenotype (SASP). They constitute chronic low-grade inflammation environment to adjacent cells and tissues. In order to find inhibiting agents of SASP formation, 113 plant constituents were incubated with BJ fibroblasts for 6 days after treatment with bleomycin. Several plant constituents showed considerable inhibition of IL-6 production, a representative SASP marker. These plant constituents included anthraquinones such as aurantio-obtusin, flavonoids including astragalin, iristectorigenin A, iristectorigenin B, linarin, lignans including lariciresinol 9-O-glucoside and eleutheroside E, phenylpropanoids such as caffeic acid and methyl caffeate, steroid (ophiopogonin), and others like centauroside, rhoifolin and scoparone...

PURPOSE: Obesity is associated with tumor promoting pathways related to insulin resistance and chronic low-grade inflammation which have been linked to various disease states, including cancer. Many studies have focused on the relationship between obesity and increased estrogen production, which contributes to the pathogenesis of estrogen receptor-positive breast cancers. The link between obesity and other breast cancer subtypes, such as triple-negative breast cancer (TNBC) and Her2/neu+ (Her2+) breast cancer, is less clear...

BACKGROUND: Obesity is associated with both impaired testosterone production and a chronic state of low grade inflammation. Previously it was believed that this inflammation was mediated by a decline in the immunosuppressive action of testosterone. However, more recently an alternative hypothesis (GELDING theory) has suggested that inflammation originating from the passage of intestinal bacteria into the circulation (metabolic endotoxaemia) may actually be the cause of impaired testicular function in obese men...

Ambreen Asghar, Nadeem Sheikh
The frequency of obesity is enormously growing worldwide. Obesity results when energy intake exceeds, energy expenditure. Excess adiposity is a major risk factor in the progress of various metabolic disorders accounting insulin resistance, hypertension, Type 2 diabetes, nonalcoholic fatty liver disease, polycystic ovarian disease and several types of cancers. Obesity is characterized by pro-inflammatory condition in which hypertrophied adipose tissue along with immune cells contribute to increase the level of pro-inflammatory cytokines...

BACKGROUND AND AIMS: Several studies demonstrated that surgery can improve inflammation parameters, such as C-reactive protein (CRP). Few biomarkers have been investigated to potentially predict type 2 diabetes mellitus (T2DM) remission. We aimed at determining whether pre-surgery serum CRP levels could predict T2DM remission after 3 years in patients undergoing bariatric surgery, especially biliopancreatic diversion (BPD). METHODS AND RESULTS: This study was conducted from 2007 to 2009 at the Surgical Department of the University of Genoa, Italy...

INTRODUCTION: Morbid obesity and obstructive sleep apnea (OSA) interact at an inflammatory level. Bariatric surgery reduces inflammatory responses associated with obesity. Heme oxygenase-1 (HO-1) is an enzyme with anti-inflammatory properties, which might be increased in morbid obesity or OSA. We studied morbidly obese patients with OSA to determine: (a) HO-1 plasma concentrations according to OSA severity and their relationship with insulin resistance and inflammation and (b) the impact of bariatric surgery on HO-1 and parameters of insulin resistance and inflammation...

Lipocalin proteins are small regulatory peptides implicated in metabolism, inflammation, and immunity. Although lipocalin proteins have been linked to various clinical conditions, their role in the acute inflammatory setting, such as acute pancreatitis (AP), has only been sparsely investigated. Two members of the lipocalin family, lipocalin-2 (LCN-2) and retinol binding protein -4 (RBP-4), play an important role in obesity and insulin resistance. In this study, we analysed circulating levels of LCN-2 and RBP-4 in 92 individuals after AP, of whom 41 individuals had abdominal obesity and 51 did not...

Irisin regulates glucose levels, lipid levels, insulin sensitivity, and low-grade inflammation. Gestational diabetes mellitus (GDM) is a common metabolic complication of pregnancy, and is associated with increased rates of perinatal problems. Oxidative stress biomarkers have a role in the pathogenesis of patients with GDM. In total, 94 patients were included in our study including 46 control patients and 48 patients with GDM. Fasting blood glucose, HOMA-IR, total oxidative stress (TOS), irisin, and oxidative stress index (OSI) levels of the patients were measured...

Expansion of white adipose tissue induce insufficient vascularization, driving hypoxia and low-grade inflammation. Resident preadipocytes are thought to be involved. We evaluated the effects of hypoxia over preadipocytes and adipocytes, to determine which cellular type impacts the most over macrophages activation. 3T3-L1 cells were either differentiated, or maintained undifferentiated. Each group was subjected to the presence or absence of chemical hypoxia (200 μM CoCl2) for 24 h. Conditioned media were used as treatment for murine RAW264...

Metabolic syndrome (MetS) is associated with obesity, dyslipidemia, type 2 diabetes, and chronic low-grade inflammation. The aim of this study was to determine the role of high-fat low-cholesterol diets (HFLCDs) rich in SFAs (HFLCD-SFAs), MUFAs (HFLCD-MUFAs) or MUFAs plus omega-3 long-chain PUFAs (HFLCD-PUFAs) on vascular calcification by the modulation of the RANKL/RANK/OPG system in the aortic roots of Lep(ob/ob)LDLR(-/-) mice. Animals fed with HFLCD-SFAs had increased weight and a greater atheroma plaque size, calcification, and RANKL/CATHK expression in the aortic root than mice on MUFA-enriched diets, with an increasing OPG expression in the aortic roots of the latter...

INTRODUCTION: Population-based studies have associated inflammation, particularly higher C-reactive protein (CRP), with depressive severity, but clinical trials in major depressive disorder were rather non-specific without examining the role of gender. We aimed to investigate the association between CRP and overall depression severity including specific depressive symptoms and to examine potential gender differences. METHODS: We included 231 individuals with major depressive disorder from the Genome-Based Therapeutics Drugs for Depression (GENDEP) study...
