Obesity, a growing health concern, is associated with an increased risk of morbidity and mortality. Chronic low-grade inflammation is implicated in obesity-driven metabolic complications. Peripheral focused ultrasound stimulation (pFUS) is an emerging non-invasive technology that modulates inflammation. Here, we reasoned that focused ultrasound stimulation of the liver may alleviate obesity-related inflammation and other comorbidities. After 8 weeks on a high-fat high-carbohydrate "Western" diet, C57BL/6J mice were subjected to either sham stimulation or focused ultrasound stimulation at the porta hepatis. Daily liver-focused ultrasound stimulation for 8 weeks significantly decreased body weight, circulating lipids and mitigated dysregulation of adipokines. In addition, liver-focused ultrasound stimulation significantly reduced hepatic cytokine levels and leukocyte infiltration. Our findings demonstrate the efficacy of hepatic focused ultrasound for alleviating obesity and obesity-associated complications in mice. These findings suggest a previously unrecognized potential of hepatic focused ultrasound as a possible novel noninvasive approach in the context of obesity.
肥胖是一个日益严重的健康问题,与发病率和死亡率的增加有关。慢性低度炎症与肥胖引起的代谢并发症有关。外周聚焦超声刺激(pFUS)是一种新兴的非侵入性技术,可调节炎症。在这里,我们认为肝脏的聚焦超声刺激可能减轻肥胖相关的炎症和其他合并症。在高脂肪高碳水化合物的“西方”饮食 8 周后,C57BL/6J 小鼠接受假刺激或肝门处的聚焦超声刺激。8 周的每日肝脏聚焦超声刺激显著降低了体重、循环脂质,并减轻了脂肪因子的失调。此外,肝脏聚焦超声刺激显著降低了肝细胞因子水平和白细胞浸润。我们的研究结果表明,肝脏聚焦超声在减轻肥胖和肥胖相关并发症方面对小鼠有效。这些发现表明,肝脏聚焦超声具有以前未被认识到的潜力,可能成为肥胖症治疗中的一种新的非侵入性方法。
