Repurposing Host Defense and Microbial Metabolism for Salmonella Gut Colonization.
Findings showing that the antimicrobial lectin RegIIIβ, together with microbiota-dependent metabolites such as fatty acid-derived cues and polyamines, can unexpectedly facilitate STm colonization support a model in which host defense programs and microbial metabolism are redirected to promote pathogen fitness, revealin...
