宿主遗传学和肠道微生物组都可以影响代谢表型。然而,宿主遗传变异是否塑造肠道微生物组并与其相互作用以影响宿主表型尚不清楚。在这里,我们比较了从 TwinsUK 人群中获得的超过 1,000 个粪便样本中的微生物群,其中包括 416 对双胞胎。我们鉴定了许多微生物类群,其丰度受到宿主遗传学的影响。最具有遗传性的分类单元,Christensenellaceae 科,与其他遗传性细菌和产甲烷古细菌形成了共现网络。此外,Christensenellaceae 及其伙伴在体重指数 (BMI) 较低的个体中含量丰富。用 Christensenella minuta(一种培养的 Christensenellaceae 成员)对与肥胖相关的微生物组进行了修改,并将其移植到无菌小鼠体内。 C. minuta 改良剂减少了受体小鼠的体重增加并改变了微生物组。我们的研究结果表明,宿主遗传学影响人类肠道微生物组的组成,并且可以通过影响宿主代谢的方式发挥作用。
Host genetics and the gut microbiome can both influence metabolic phenotypes. However, whether host genetic variation shapes the gut microbiome and interacts with it to affect host phenotype is unclear. Here, we compared microbiotas across > 1,000 fecal samples obtained from the TwinsUK population, including 416 twin-pairs. We identified many microbial taxa whose abundances were influenced by host genetics. The most heritable taxon, the family Christensenellaceae, formed a cooccurrence network with other heritable Bacteria and with methanogenic Archaea. Furthermore, Christensenellaceae and its partners were enriched in individuals with low body mass index (BMI). An obese-associated microbiome was amended with Christensenella minuta, a cultured member of the Christensenellaceae, and transplanted to germfree mice. C. minuta amendment reduced weight gain and altered the microbiome of recipient mice. Our findings indicate that host genetics influence the composition of the human gut microbiome and can do so in ways that impact host metabolism.
