本期Nature封面所示为粪便细菌的一个扫描电子显微镜图像。肥胖与栖息在我们肠道中的上万亿微生物的变化相关,但机制还不清楚。在Nature发表的一项新的研究中,耶鲁大学领导的研究小组发现了肠道微生物的改变是如何导致肥胖的。

在早期的研究里,Gerald I. Shulman医学博士和医学教授George R. Cowgill 发现乙酸——一个短链的脂肪酸刺激啮齿类动物的胰岛素分泌。Howard Hughes医学研究所的研究员Shulman和一个耶鲁大学研究团队为了了解更多关于乙酸的作用,在啮齿动物的肥胖模型中进行了一系列的实验。

实验确定肠道菌通过乙酸让胰岛素增加

研究小组比较了乙酸相对于其它短链脂肪酸的效应,发现在高脂肪饮食的动物体内有较高的乙酸含量。他们还观察到注入乙酸在胰腺的β细胞中刺激胰岛素的分泌,但还不清楚机制是如何的。

下一步,研究人员确定了当乙酸直接注射到大脑中,它通过激活副交感神经系统刺激胰岛素的增加。Shulman说:“乙酸通过一个集中调节的机制刺激β细胞分泌更多的胰岛素。它还可以刺激激素胃泌素和生长素的分泌,从而增加食物的摄入量。”

最后,该研究小组试图建立肠道菌群和胰岛素增加之间的因果关系。在排泄物从一组啮齿类动物转移到另一组后,他们观察到在肠道菌群、乙酸水平和胰岛素有类似的变化。

Shulman和他的同事发现乙酸不直接刺激胰腺的β细胞分泌胰岛素。相反,乙酸以某种方式影响大脑通过迷走神经向胰腺发出“制造胰岛素”的信号。

这样的作用会推动增肥

Shulman说:“综合这些实验证明在肠道菌响应饮食的变化而改变和乙酸产量的增加之间存在因果联系。增加的乙酸反过来会增加食物的摄入量,引发一个正反馈循环,从而推动肥胖和对胰岛素的抵抗。”

该研究的作者认为,这种积极的正反馈循环可能是在进化过程中起重要作用,促使动物在食物匮乏的时代偶然发现了高热量的食物时胖起来。



在啮齿动物中的新研究表明:肥胖可能从肠道微生物开始,肠道菌将食物中的脂肪变成乙酸。乙酸则通过迷走神经向胰腺和胃发出信号。胰腺内β细胞释放胰岛素,这会导致脂肪细胞储存更多的脂肪。对胃的信号是告诉其制备饥饿荷尔蒙ghrelin,这可能会引起暴饮暴食。

Shulman说:“肠道菌群的改变与肥胖和在人类及啮齿类动物的代谢综合症都有关。在这项研究中,我们提供了一种新的机制来解释啮齿类动物中的这种生物现象。我们正在研究这一机制是否也存在于人类中。”如果研究人员确认相同的过程也发生在人类中,他们会鉴定出产生醋酸的细菌并找到如何制止它们的方法,这可能导致新的治疗肥胖的方案。

Cell Host & Microbe:抗生素可扰乱肠道内的氧含量和纤维分解促进致病菌的生长来自加州大学-戴维斯分校的一项新的研究进一步揭示了抗生素治疗的潜在危害性,研究发现抗生素可扰乱肠道内的氧水平和纤维的分解从而促进致病菌的生长繁殖。该研究成果已在线发表于Cell Host & Microbe。20世纪40年代以来抗生素的使用拯救饿无数的生命,但是抗生素耐药性的发生,以及对抗生

Science:控制肠道菌群健康的69种因子

图片来源:www.sciencealert.com 在我们肠道深处存在着非常繁荣昌盛的一种微型生态系统,这就是肠道微生物组(肠道菌群),肠道菌群的微妙平衡对于维持机体健康和消化系统的功能非常重要;如今来自比利时的研究人员通过对从巧克力到避孕药的多种和人类息息相关的产品进行筛查,鉴别出了69种不同的因子可以影响机体肠道微生物组的组成,相关研究刊登于国际杂志Science上。 提及影响肠道菌群

Genome Med:肠道菌群与化疗后血液感染有何联系?

近期,一项在线发表于《Genome Medicine》上的最新研究表明,肠道中的细菌可能预测大剂量化疗后危及生命的血液感染的风险。这项研究由明尼苏达大学和南特大学医院的研究者领导进行。 每年大约有20000名癌症患者接受高剂量化疗为骨髓或干细胞移植做准备。通常约有20%-40%的患者发生化疗后血液感染。可悲的是,约15%–30%的患者因感染而死亡。 目前

AEM:母乳与婴儿肠道菌群之间存在共生关系

婴儿的胃肠道富含特定保护性微生物。母乳会引导新生儿的肠道菌群发展成为特异性菌群,反过来,肠道菌群会给肠道提供营养并保护孩子健康。来自加州大学戴维斯分校的研究小组经研究已经确定了母乳中存在一种复合物可以提供营养成分,并且在牛奶中也发现了该复合物成分。这项研究发现饮用牛奶可为婴儿提供益生元等营养成分。该研究相关论文4月15日发表在美国微生物学会下属《应用与环境微生物学》杂志上。 在早期的研究中, 由

抗菌牙膏不会影响肠道菌群和口腔微生物

根据小型随机试验测定,一些含有抗生素三氯生的个人卫生用品,如肥皂和牙膏,对微生物群落或内分泌功能没有重大影响。这项研究结果在线发表在mSphere上。 “有很多人害怕三氯生,但在我们的研究中我们没有发现任何相关的支持论点。“医学博士Julie Parsonnet说,“当大多数抗生素应用到人类中,这些抗生素是微生物群中的原子弹,但我们发现,当人们通过正常家庭用品接触到三氯生后它没有对我们的微生物生
