虽然激活米色产热是治疗肥胖相关疾病的一种有前途的方法,但目前还没有已知的药理学方法来诱导人类的米色。间歇性禁食是控制体重的一种有效和自然的策略,但其有效性的机制尚不清楚。在这里,我们表明,每隔一天禁食(EODF)方案选择性地刺激米色脂肪的发展在白色脂肪组织,并显着改善肥胖,胰岛素抵抗和肝脂肪变性。EODF处理导致肠道微生物群组成的转变,导致发酵产物乙酸盐和乳酸盐的升高,以及米色细胞中单羧酸转运蛋白1表达的选择性上调。微生物群耗尽的小鼠对EODF诱导的beiging具有抗性,而将来自EODF处理的小鼠的微生物群移植到微生物群耗尽的小鼠中激活beiging并改善代谢稳态。这些发现为激活脂肪组织布朗宁和治疗代谢性疾病提供了一种新的肠道微生物群驱动机制。白色脂肪米色是一种很有前途的治疗肥胖症和相关代谢性疾病。在此,Li,Xie等人发现EODF方案可以选择性地诱导白色脂肪组织变黑,随后改善小鼠的代谢紊乱。肠道微生物群协调EODF对甜菜碱和代谢改善的影响。
While activation of beige thermogenesis is a promising approach for treatment of obesity-associated diseases, there are currently no known pharmacological means to induce beiging in humans. Intermittent fasting is an effective and natural strategy for weight control, but the mechanism for its efficacy is poorly understood. Here, we show that an every other day fasting (EODF) regimen selectively stimulates beige fat development within white adipose tissue, and dramatically ameliorates obesity, insulin resistance and hepatic steatosis. EODF treatment results in a shift in the gut microbiota composition leading to the elevation of the fermentation products acetate and lactate, and the selective upregulation of monocarboxylate transporter 1 expression in beige cells. Microbiota-depleted mice are resistance to EODF-induced beiging, while transplantation of the microbiota from EODF-treated mice to microbiota-depleted mice activates beiging and improves metabolic homeostasis. These findings provide a new gut microbiota-driven mechanism for activating adipose tissue browning and treating metabolic diseases. White adipose beiging is a promising therapy for obesity and related metabolic diseases. Here, Li, Xie et al. find that an EODF regimen can selectively induce the beiging of white adipose tissue and subsequently ameliorate metabolic disorders in mice. Gut microbiota orchestrate the effects EODF on beiging and metabolic improvement.
