Adiponectin, an adipocyte-derived hormone, attenuates the production of TNFalpha by activated human macrophages. In the present study, we used porcine blood-derived macrophages to test the hypothesis that the anti-inflammatory action of adiponectin includes suppression of IL6 and an induction of IL10. Adiponectin suppressed both TNFalpha and IL6 production(More)
Fatty acids and their metabolites regulate gene expression and immunological pathways. Furthermore, obese individuals frequently have increased circulating fatty acid concentrations, and localized inflammation in adipose tissue may facilitate the systemic inflammation associated with the insulin resistance of obesity. Although palmitate induces inflammation(More)
The quality and value of the carcass in domestic meat animals are reflected in its protein and fat content. Preadipocytes and adipocytes are important in establishing the overall fatness of a carcass, as well as being the main contributors to the marbling component needed for consumer preference of meat products. Although some fat accumulation is essential,(More)
Obesity and insulin resistance are often associated with lower circulating adiponectin concentrations and elevated serum interleukin-6 (IL-6) and/or tumor necrosis factor-alpha (TNF-alpha). Adiponectin suppresses activation of nuclear factor-kappaB (NF-kappaB) in aortic endothelial cells and porcine macrophages. Accordingly, we hypothesized that adiponectin(More)
Muscle growth in meat animals is a complex process governed by integrated signals emanating from multiple endocrine and immune cells. A generalized phenomenon among meat animal industries is that animals commonly fail to meet their genetic potential for growth in commercial production settings. Therefore, understanding the impact of stress and disease on(More)
Obesity leads to changes in the gut microbial community which contribute to the metabolic dysregulation in obesity. Dietary fat and fiber affect the caloric density of foods. The impact of dietary fat content and fiber type on the microbial community in the hind gut is unknown. Effect of dietary fat level and fiber type on hindgut microbiota and volatile(More)
We recently provided evidence that interleukin-15 (IL-15) is expressed lowly in the pig adipocyte and that interferon-gamma (IFN-gamma) markedly increases this expression through a pathway regulated in part by protein kinase C. In the present study, we tested the hypothesis that IL-15 acts directly on the adipocyte to regulate lipid accretion by enhancing(More)
Adiponectin is an adipocyte-derived hormone that has been implicated recently in the regulation of inflammation in immunocytes, and in lipid metabolism and glucose homeostasis in liver, skeletal muscle and adipocytes. However, information in non-rodent models is limited. We have cloned and sequenced the porcine adiponectin open reading frame and evaluated(More)
The incidence of obesity and its comorbidities, such as insulin resistance and type II diabetes, are increasing dramatically, perhaps caused by the change in the fatty acid composition of common human diets. Adipose tissue plays a role as the major energy reservoir in the body. An excess of adipose mass accumulation caused by chronic positive energy balance(More)
inhibits LPS-induced NF-␬B activation and IL-6 production and increases PPAR␥2 expression in adipocytes. and insulin resistance are often associated with lower circulating adiponec-tin concentrations and elevated serum interleukin-6 (IL-6) and/or tumor necrosis factor-␣ (TNF-␣).
