J EXP MED:脂肪褐变助力肥胖治疗

2018-01-06 海北 MedSci原创

已有的研究显示,血管生成在脂肪组织的数量和代谢的调节中起着非常重要作用。因此,靶向脂肪组织的血管可以为肥胖和代谢紊乱的治疗提供一个很好的机会。

已有的研究显示,血管生成在脂肪组织的数量和代谢的调节中起着非常重要作用。因此,靶向脂肪组织的血管可以为肥胖和代谢紊乱的治疗提供一个很好的机会。

近日,来自瑞典卡罗林斯卡学院的研究人员发文报导,VEGFR1在调节脂肪血管生成,肥胖,和整体代谢中的生理功能。对内皮细胞VEGFR1的药理学抑制,或遗传敲除,能够增加脂肪血管的生成,促进皮下白色脂肪组织的褐变,导致产热升高。

在饮食诱导的肥胖模型中,内皮VEGFR1的缺失可以改善整体代谢,从而表现出有效的抗肥胖作用。伴随着代谢改变,脂肪肝和胰岛素敏感性也在VEGFR1缺陷的高脂饮食(HFD)饲养的小鼠中有了显着的改善。

因此,研究人员的数据表明,靶向VEGFR1为治疗肥胖和代谢性疾病(如肝脂肪变性和2糖尿病)提供了值得期待的新机会。
