In this study, we investigated effects of pine nut oil (PNO) on high-fat-diet (HFD)-induced obesity and metabolic dysfunction in skeletal muscle and brown adipose tissue (BAT). Male C57BL/6 mice were fed a HFD with 15% energy from lard and 30% energy from either soybean oil (SBO-HFD) or PNO (PNO-HFD) for 12 weeks. The PNO-HFD resulted in less weight gain(More)
Metabolic dysregulation (e.g., hyperglycemia, hyperinsulinemia, hyperlipidemia, etc.) is a hallmark of obesity-related diseases such as insulin resistance, type 2 diabetes, and fatty liver disease. In this study, we assessed whether dietary capsaicin attenuated the metabolic dysregulation in genetically obese diabetic KKAy mice, which have severe diabetic(More)
Obesity-induced adipose inflammation is characterized by recruitment of macrophages to adipose tissue and release of inflammatory cytokines. 4-1BB, a costimulatory receptor, modulates inflammatory processes through interaction with its ligand 4-1BBL on immune cell surfaces. In this study, we examined whether a 4-1BB/4-1BBL interaction between adipocytes and(More)
Adipose macrophages with the anti-inflammatory M2 phenotype protect against obesity-induced inflammation and insulin resistance. Heme oxygenase-1 (HO-1), which elicits antioxidant and anti-inflammatory activity, modulates macrophage phenotypes and thus is implicated in various inflammatory diseases. Here, we demonstrate that the HO-1 inducer, hemin,(More)
Immune cells (e.g. macrophages and T cells) in adipose tissue play a crucial role in the development of obesity-induced inflammation and metabolic disorders. Here we report findings suggesting that the immune signaling molecule 4-1BB/CD137 is a novel target for treatment of obesity and metabolic disorders. 4-1BB stimulation with agonistic antibody reduced(More)
BACKGROUND 4-1BB, a member of the TNF receptor superfamily, has a role in various inflammatory pathologies through its interaction with 4-1BB ligand. We previously demonstrated that it participates in initiating and promoting obesity-induced adipose inflammation in a rodent model. OBJECTIVE In this study, we examined whether 4-1BB is related to(More)
Obesity-induced skeletal muscle inflammation is characterized by increased macrophage infiltration and inflammatory cytokine production. In this study, we investigated whether 4-1BB, a member of the TNF receptor superfamily (TNFRSF9) that provides inflammatory signals, participates in obesity-induced skeletal muscle inflammation. Expression of the 4-1BB(More)
Obesity-induced monocyte/macrophage proliferation and activation play a crucial role in various chronic inflammatory metabolic disorders, such as insulin resistance, diabetes mellitus, and atherosclerosis. 4-1BBL, a member of the tumor necrosis factor superfamily expressed on monocytes/macrophages, provides inflammatory signals to modulate their(More)
Obesity-induced inflammation causes skeletal muscle atrophy accompanied by disruption of oxidative metabolism and is implicated in metabolic complications such as insulin resistance and type 2 diabetes. We previously reported that 4-1BB, a member of the tumor necrosis factor receptor superfamily, participated in obesity-induced skeletal muscle inflammation.(More)
Obesity-induced hypothalamic inflammation is characterized by activation of microglia, which are resident macrophages of the central nervous system, and is implicated in the derangement of energy homeostasis, metabolic complications, and neurodegenerative diseases. Quercetin, a naturally occurring flavonoid, is known to protect against oxidative stress and(More)
