Abstract

We investigated how the gut microbiota modulate anti-viral immunity in mouse models of infection. We showed that gut bacteria are vital for the presence of low level of type-I interferons, key mediators in anti-viral immunity. The gut bacteria deliver DNA in vesicles to host cells, priming anti-viral immunity.
