Obesity is a pandemic disease associated with many metabolic alterations and involves several organs and systems. The endocannabinoid system (ECS) appears to be a key regulator of energy homeostasis and metabolism. Here we show that specific deletion of the ECS synthesizing enzyme, NAPE-PLD, in adipocytes induces obesity, glucose intolerance, adipose tissue inflammation and altered lipid metabolism. We report that Napepld-deleted mice present an altered browning programme and are less responsive to cold-induced browning, highlighting the essential role of NAPE-PLD in regulating energy homeostasis and metabolism in the physiological state. Our results indicate that these alterations are mediated by a shift in gut microbiota composition that can partially transfer the phenotype to germ-free mice. Together, our findings uncover a role of adipose tissue NAPE-PLD on whole-body metabolism and provide support for targeting NAPE-PLD-derived bioactive lipids to treat obesity and related metabolic disorders.
肥胖是一种与多种代谢改变相关的大流行疾病，涉及多个器官和系统。内源性大麻素系统（ECS）似乎是能量稳态和代谢的关键调节因子。在此我们表明，脂肪细胞中ECS合成酶NAPE-PLD的特异性缺失会导致肥胖、葡萄糖不耐受、脂肪组织炎症和脂质代谢改变。我们报告称，Napepld基因缺失的小鼠呈现出改变的褐色化程序，对冷诱导褐色化的反应较弱，这突出了NAPE-PLD在生理状态下调节能量稳态和代谢中的重要作用。我们的结果表明，这些改变是由肠道微生物群组成的变化介导的，这种变化可将表型部分转移给无菌小鼠。总之，我们的研究结果揭示了脂肪组织NAPE-PLD在全身代谢中的作用，并为靶向NAPE-PLD衍生的生物活性脂质治疗肥胖及相关代谢紊乱提供了支持。
