摘要

对啮齿动物和人类的研究已经建立了肠道微生物群和肥胖之间的关系,但我们的肠道居民如何促进或抑制体重增加还不太清楚。《自然代谢》杂志上的一篇论文表明,某些微生物代谢物通过调节宿主的肠道免疫反应,在小鼠中具有抗肥胖作用。作者在一个大型中国队列中发现了人类血清中微生物芳香氨基酸(AAA)代谢物(包括4-羟基苯基乙酸(4HPAA))与体脂肪积累之间的关联。然后,他们发现4HPAA及其结构相关的类似物3-和4-羟基苯基丙酸(分别为3HPP和4HPP)在口服时抑制高脂肪饮食(HFD)小鼠的体重增加,但值得注意的是,腹腔注射时没有。同样,只有口服AAA代谢物才能防止喂食HFD的小鼠出现典型的脂肪细胞肥大。在hfd喂养的小鼠中,4HPAA及其类似物也减轻了常伴随肥胖的肝脂肪变性。
