The effect of cluster of differentiation (CD)36 on regulatory T cells (Treg) was investigated in gonadal (GN) adipose tissues and mesenteric lymph nodes (MLN) of wild-type (WT) and CD36 deficient (CD36(-/-)) mice kept on standard fat (SFD, lean) or on high fat diet (HFD, obese). GN adipose tissue mass was smaller, but MLN size larger for obese CD36(-/-) versus obese WT mice. Overall, the reduction of Treg cells in GN adipose tissue and MLN after a HFD is much more prominent in WT than CD36(-/-) mice. Moreover, CD36(-/-) mice may be protected against obesity-related chronic inflammation.

Brown adipose tissue (BAT) is an ideal target organ for obesity treatment. Resinacein S is extracted from Ganoderma lucidum and can elevate Uncoupling protein 1 (UCP1) in cells, but its related effects at the animal level are not clear. The mice were fed with high-fat diet to construct obesity models and treated with Resinacein S.

Rationale: Wildlife scientists are quantifying steroid hormones in a growing number of tissues and employing novel methods that must undergo validation before application. This study tested the accuracy and precision of liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods for use on blubber samples from short-finned pilot whales (Globicephala macrorhynchus). We expanded upon a method for corticosteroid quantification by adding analytes and optimizing internal standard (IS) application.

Obesity, often driven by high-fat diets (HFD), is a major global health issue, necessitating effective preventive measures. Tetragonia tetragonoides, a plant with known medicinal properties, has not been extensively studied for its effects on HFD-induced obesity and related genetic changes in mice. This study explores the impact of Tetragonia tetragonoides extract (TTE; 300 mg/kg) on obesity-related traits in C57BL/6J male mice, with a focus on transcriptomic changes in the liver and white adipose tissue (WAT).

Lipophagy is a way to degrade lipids; however, the molecular mechanisms are not fully understood. Using the holometabolous lepidopteran insect Helicoverpa armigera, cotton bollworm, as a model, we revealed that the larval fat body undergoes lipophagy during metamorphosis, and lipophagy is essential for metamorphosis. The steroid hormone 20-hydroxyecdysone (20E) induced lipophagy by promoting the expression of the peptide hormone adipokinetic hormone (AKH, the insect analog of glucagon) and the adipokinetic hormone receptor (AKHR).

FXR, encoded by Nh1r4, is a nuclear receptor crucial in regulating bile acid, lipid, and glucose metabolism. Prior research has indicated that activating FXR in the liver and small intestine may offer protection against obesity and metabolic diseases. This study demonstrates the essential role of the FXR-ApoC2 pathway in promoting the browning of white adipose tissue (WAT).
