BACKGROUND: Binding of beta 1,3/1,6 glucan of Ganoderma lucidum (G. lucidum) with the receptor results in a series of signal transfers (signalling cascades), which activates the transcription factors for regulating inflammation. Excess cholesterol intake leads to an increase in the distance between fat cells and capillaries, which may cause hypoxia in the fat tissue of obese mice. This hypoxia induces the death of fat cells, resulting in the inflammation of adipose tissue or an increase in the inflammatory gene expression associated with obesity...

Adaptive immunity has been implicated in adipose tissue inflammation, obesity and its adverse metabolic consequences. No obesity-related autoantigen has yet been identified, although heat shock protein 60 (HSP60) has been implicated in other autoimmune diseases. We investigated whether feeding a high fat diet to C57BL/6J mice would cause autoimmunity to HSP60 and whether immunomodulation with peptides from HSP60 would reverse the resulting obesity or metabolic dysfunction. Obese mice had higher circulating levels of HSP60 associated with increased T-lymphocyte proliferation responses and the emergence of circulating IgG1 and IgG2c antibody levels against HSP60...

The aim of the study was to determine the influence of exendin-4 intervention on non-obese diabetic (NOD) mouse blood and the pancreatic tissue immune microenvironment. A total of 40 clean NOD mice were used in the study and randomly divided into 4 groups (n=10/group). The first group was blank control group D with normal saline intervention, and with different doses of exendin, i.e.,-4 2, 4 and 8 µg/kg/day. The three remaining groups were: i) Low-dose group A; ii) medium-dose group B; and iii) high-dose group C...

In type 1 diabetes, restoration of normoglycemia can be achieved if the autoimmune attack on beta cells ceases and insulin requirement is met by the residual beta cells. We hypothesize that an adjunctive therapy that reduces insulin demand by increasing insulin sensitivity will improve the efficacy of an immunotherapy in reversing diabetes. We tested the gut microbiota-modulating prebiotic, oligofructose (OFS), as the adjunctive therapy. We treated non-obese diabetic mice with an immunotherapy, monoclonal anti-CD3 antibody (aCD3), with or without concurrent dietary supplement of OFS...

BACKGROUND: Obesity is associated with chronic low-grade inflammation leading to insulin resistance and diabetes. Adiponectin is an adipokine that regulates inflammatory responses. The aim of our study was to investigate whether any effects of adiponectin against obesity and insulin-resistance may depend on the adaptive immune system. METHODS: We treated high-fat-diet fed Rag1-/- mice lacking mature lymphocytes with adiponectin over 7weeks and investigated alterations in their metabolic outcome and inflammatory state...

Obesitychanges the regulatorymechanisms of the immune system, resulting in impaired immunity. In cancer immune mechanisms, the greater the degree of obesity, the lower the activity of the lymphocytes. Herein, we examined the relationship between obesity and lymphocytes in breast cancer patients undergoing chemotherapy. We recruited 10 recurrent or metastatic breast cancer patients who were administered eribulin. Using bodymass index(BMI), we classified these patients into a non-obese group(BMI<25)and an obese group(BMI>25)...

Hyperlipidemia, which is closely associated with a fatty diet and aging, is commonly observed in the western and aged society. Therefore, a novel therapeutic approach for this disease is critical, and an immunological view has been suggested as a novel strategy, because hyperlipidemia is closely associated with inflammation and immune dysfunction. In this study, the effects of an aqueous extract of Rubus occidentalis (RO) in obese mice were investigated using immunological indexes. The mice were fed a high-fat diet (HFD) to induce hyperlipidemia, which was confirmed by biochemical analysis and examination of the mouse physiology...

Yerba mate (YM) has been shown to have anti-inflammatory properties in several studies. However, this effect has been found mainly in obesity-related inflammation. The aim of this work was to study the effect of YM on cultured peripheral blood mononuclear cells to see whether it has anti-inflammatory properties. We stimulated peripheral blood mononuclear cells in vitro with phytohemagglutinin (PHA) in the presence of yerba mate and determined their activation by measuring the expression of CD25 by flow cytometry...

Psoriasis is a systemic disease with numerous concomitant metabolic disorders. Apparently, T-helper 17 lymphocytes and interleukin (IL)-17 constitute an important element linking those disorders. The role of IL-17 has been confirmed by numerous studies, although it remains not completely understood, and the study results are controversial. Based on the studies performed so far, it is assumed that IL-17 contributes to development of atherosclerosis by means of: stimulation of production of proinflammatory compounds; induction of apoptosis of endothelial cells and heart muscle cells; stimulation of von Willebrand factor production; and induction of the matrix metalloproteinase-9 (atherosclerotic plaque rupture)...

Genetic- and diet-induced obesity and insulin resistance are associated with an increase in mechanistic target of rapamycin complex (mTORC) 1 activity in adipose tissue. We investigated herein the effects of pharmacological mTORC1 inhibition in the development of adipose tissue inflammation induced by high-fat diet (HFD) feeding, as well as in the polarization, metabolism and function of bone marrow-derived macrophages (BMDM). For this, C57BL/6J mice fed with a standard chow diet or a HFD (60% of calories from fat) and treated with either vehicle (0...

The lymphatic system works in close collaboration with the cardiovascular system to preserve fluid balance throughout the body and is essential for the trafficking of antigen-presenting cells and lymphocytes to lymphoid organs. Recent findings have associated lymphatic dysfunction with the pathogenesis of cardiovascular-related diseases such as atherosclerosis, inflammation and obesity. Whether lymphatic dysfunction is a cause or a consequence of these diseases, as well as how, is under intensive investigation...

AIMS/HYPOTHESIS: In obesity oxidative stress is thought to contribute to the development of insulin resistance, non-alcoholic fatty liver disease and the progression to non-alcoholic steatohepatitis. Our aim was to examine the precise contributions of hepatocyte-derived H2O2 to liver pathophysiology. METHODS: Glutathione peroxidase (GPX) 1 is an antioxidant enzyme that is abundant in the liver and converts H2O2 to water. We generated Gpx1 (lox/lox) mice to conditionally delete Gpx1 in hepatocytes (Alb-Cre;Gpx1 (lox/lox)) and characterised mice fed chow, high-fat or choline-deficient amino-acid-defined (CDAA) diets...

BACKGROUND: Hidradenitis suppurativa (HS) is a chronic inflammatory disease affecting skin sites with a high density of apocrine glands. HS commonly presents after puberty, with most patients diagnosed in the second decade of their life. Several studies have investigated smoking, obesity, hypertension, diabetes, and dyslipidemia as possible underlying risk factors for HS. However, we encountered 2 patients with a long-standing history of untreated leukemia who developed late-onset HS...

Allergic asthma and obesity are the leading health problems in the world. Many studies have shown that obesity is a risk factor of development of asthma. However, the underlying mechanism has not been well established. In this study, we demonstrate that leptin, an adipokine elevated in obese individuals, promoted proliferation and survival of pro-allergic type 2 helper T cells and group 2 innate lymphoid cells and production of type 2 cytokines, which together contribute to allergic responses. Leptin activates mTORC1, MAPK, and STAT3 pathways in TH2 cells...
