The gut-brain axis goes viral

A cloudburst of recent research has revealed important contributions of indigenous microbes to host neurological functions. In this issue of Cell Host & Microbe, Mayberis-Perxachs and Castells-Nobau et al. uncover a role for gut-resident bacteriophages in microbiome structure and metabolism with downstream effects on neuronal gene expression and cognition.
