Abstract Obesity exhibits a correlation with metabolic inflammation and endoplasmic reticulum stress, promoting the progression of disease such as diabetes, hyperlipidemia, hyperuricemia so on. Adipose tissue macrophages (ATMs) are central players in obesity-associated diseases. Macrophages involved lipid energy metabolism mitochondrial function adipocytes. Macrophage polarization is accompanied by shifting between glycolysis oxidative phosphorylation. Here, this review focuses on macrophage linked to functional phenotypes an emphasis adipose physiological pathophysiological processes. In particular, interplay ATMs adipocytes metabolism, glycolysis, OXPHOS, iron handing even interactions nervous system have been reviewed. Overall, understanding protective pathogenic roles can potentially provide strategies prevent treat obesity-related disorders.

In the veterinary sector, many papers deal with relationships between inflammation and oxidative stress. However, few studies investigate mechanisms of action oxidised molecules in regulation immune cells. Thus, authors often assume that these events, sometime leading to stress, are conserved among species. The aim this review is draw state-of-the-art current knowledge about role dietary antioxidant compounds cell functions suggest some perspectives for future investigations animals interest.

Excess body weight, including overweight and obesity, is one of the major factors influencing human health, plays an important role in global burden disease. Carotenoids serve as precursors vitamin A-related retinoids, are considered to have potential effects on many diseases. However, influence carotenoids people with excess weight unclear. This meta-analysis was conducted assess or obese subjects utilizing available evidence. We searched PubMed, Medline, Cochrane Library, Web Science EMBASE databases up September 2020. Random models were used calculate standard mean differences (SMDs) odds ratios (ORs) their 95% confidence intervals (95% CIs). A total seven randomized controlled trials eight observational studies met inclusion criteria contained 28 944 data multiple carotenoid subgroups, lycopene, astaxanthin, cryptoxanthin, α-carotene, β-carotene. In all included Randomized Controlled Trial (RCT), intervention duration 20 days at shortest 16 weeks longest, range doses 1.2-60 mg d-1. Our study found that insufficiency serum a risk factor for obesity (OR = 1.73, CI [1.57, 1.91], p < 0.001). Moreover, supplementation significantly associated reductions (SMD -2.34 kg, [-3.80, -0.87] 0.001), mass index decrease (BMI, SMD -0.95 kg cm-2, [-1.88, -0.01] 0.001) waist circumference losses (WC, -1.84 cm, [-3.14, -0.54]cm, summary, show promising subjects.

The antiobesity efficacy and underlying mechanisms of polysaccharides extracted from Fu brick tea (FBTP) were investigated. An 8-week administration FBTP dose-dependently inhibited increases in body weight weights the epididymal-, retroperitoneal- inguinal-white adipose tissues stimulated beige-fat development brown tissue-derived nonshivering thermogenesis high-fat diet-induced obese mice. protected against obesity-associated abnormality serum adiponectin leptin, indicating its positive regulation energy metabolism. reversed gut dysbiosis by enriching beneficial bacteria, for example, Lactobacillus, Parabacteroides, Akkermansia, Bifidobacterium, Roseburia. Results fecal microbiota transplantation further confirmed that FBTP-induced microbial shifts contributed to browning thermogenesis, thereby alleviating host adiposity, glucose homeostasis, dyslipidemia, related hepatic steatosis. Our study demonstrates great potential with prebiotic-like activities preventing obesity metabolic complications via microbiota-derived enhancement fat burning expenditures.
