肠道微生物组深刻影响宿主生理和行为的许多方面。在这里,我们报告肠道微生物组调节了果蝇中的侵略性行为。我们发现,无菌雄性在男性间攻击中显示出大幅度降低,可以通过微生物再殖民化来挽救。这些无菌的男性与女性交配不如野生型男性那样具有竞争力,尽管他们表现出规律的运动和求爱行为。我们进一步发现,果蝇微生物组在关键发育期与饮食相互作用,以适当表达章鱼胺和成年男性侵略性的表现。这些发现提供了有关肠道微生物组如何通过与饮食相互作用在发育过程中调节特定宿主行为的见解。 肠道微生物组调节许多物种的行为。在这里,作者表明,果蝇中肠道微生物组的耗竭可降低侵袭性行为,以章鱼依赖性方式降低。
Gut microbiome profoundly affects many aspects of host physiology and behaviors. Here we report that gut microbiome modulates aggressive behaviors in Drosophila. We found that germ-free males showed substantial decrease in inter-male aggression, which could be rescued by microbial re-colonization. These germ-free males are not as competitive as wild-type males for mating with females, although they displayed regular levels of locomotor and courtship behaviors. We further found that Drosophila microbiome interacted with diet during a critical developmental period for the proper expression of octopamine and manifestation of aggression in adult males. These findings provide insights into how gut microbiome modulates specific host behaviors through interaction with diet during development.
