Effects of gut microbiota on stress response and behavioral phenotype of the host

Gut microbiota are involved in host patho-physiological functions; however, little is known about whether or not they can affect brain function. Several recent works including ours have shown that gut microbiota play a critical role in the determination of stress response and behavioral phenotype of the host. We here review recent advances in this area, i.e. the interaction between gut microbiota and the brain-gut axis, based on our series of experimental data.
