Andrographolide modulates glucose metabolism in visceral adipose tissue in an Alzheimer's disease obese mouse model.

ABSTRACT: Midlife obesity and high adiposity are recognized as risk factors for Alzheimer's disease (AD), with visceral adipose tissue (VAT) playing a central role due to its endocrine and metabolic activity. Disturbances in VAT metabolism and adipokine secretion exacerbate AD pathology. Andrographolide (Andro), known for its anti-diabetic properties, enhances neuronal glucose uptake and alleviates AD pathology. However, its effects on VAT metabolism in AD remain unexplored. This study aimed to investigate the impact of Andro on glucose metabolism in VAT using a high-fat diet (HFD)-induced obesity model in AD mice (APP/PS1). APP/PS1 mice were fed an HFD and received Andro injections (2 mg/kg, three times a week for 16 weeks). VAT samples were analyzed for glucose uptake, glycolytic rate, pentose pho
