据报道,雷公藤红素是一种从中药中提取的化合物,是一种有效的抗肥胖剂,但其机制存在争议。在这里,C57BL/6J 和瘦素缺乏 (ob/ob) 小鼠在接受雷公藤红素治疗后均表现出体重减轻,这与之前的观点相反,即雷公藤红醇通过敏化瘦素信号传导来改善肥胖。更重要的是,雷公藤红素下调了肠道中的脂质转运蛋白,增加了粪便中的脂质排泄,并减少了 HFD 小鼠的体重增加。同时,对肠道微生物群的分析表明,雷公藤红醇改变了高脂饮食喂养小鼠的肠道微生物群组成,而通过抗生素或粪便微生物移植来调节肠道微生物群则阻断了雷公藤红醇对肠道脂质运输和体重增加的影响,这表明肠道微生物群组成在介导高脂饮食下雷公藤红醇的抗肥胖作用中发挥着关键作用。总之,研究结果表明,雷公藤红素通过在高脂饮食喂养下重置肠道微生物群分布,减少肠道脂质吸收,从而对抗肥胖。雷公藤红素可减少肠道脂质转运蛋白和脂质吸收 雷公藤红素可重置肠道微生物群特征以调节肠道脂质转运 雷公藤红素可减轻喂食高脂肪饮食的瘦素缺乏 (ob/ob) 小鼠的肥胖症内分泌学;微生物学;微生物组生理学
Celastrol, a compound extracted from traditional Chinese medicine, has been reported as a potent anti-obesity agent with controversial mechanisms. Here both C57BL/6J and leptin-deficient (ob/ob) mice fed a high-fat diet (HFD) displayed body weight loss after celastrol therapy, opposing the previous viewpoint that celastrol improves obesity by sensitizing leptin signaling. More importantly, celastrol downregulated lipid transporters in the intestine, increased lipid excretion in feces, and reduced body weight gain in HFD mice. Meanwhile, analysis of gut microbiota revealed that celastrol altered the gut microbiota composition in HFD-fed mice, and modulating gut microbiota by antibiotics or fecal microbiota transplantation blocked the celastrol effect on intestinal lipid transport and body weight gain, suggesting a critical role of the gut microbiota composition in mediating the anti-obesity role of celastrol under HFD. Together, the findings revealed that celastrol reduces intestinal lipid absorption to antagonize obesity by resetting the gut microbiota profile under HFD feeding. Celastrol reduced intestinal lipid transporters and lipids absorption Celastrol reset gut microbiota profile to modulate intestinal lipid transport Celastrol attenuated obesity in leptin-deficient (ob/ob) mice fed high fat diet Biological Sciences; Endocrinology; Microbiology; Microbiome Physiology
