Innate immune system signaling and CD11b+CD11c+CD103+ cell migration to the brain underlie changes in mouse behavior after microbial colonization.

This study identifies innate immune signaling and CD11b+CD11c+CD103+ cell migration to the brain as mechanisms linking microbial colonization to behavioral changes in mice.

Microbiota-dependent in vivo biotransformation, accumulation, and excretion of arsenic from arsenobetaine-rich diet

This study shows that gut microbiota in mice transform arsenobetaine into toxic arsenic species, affecting its accumulation and excretion.

Component specific responses of the microbiomes to common chemical stressors in the human food chain

This study examines how chemical stressors affect microbiomes across different food chain components, finding component-specific responses and shifts in microbial composition and stability.

The lactonase BxdA mediates metabolic adaptation of maize root bacteria to benzoxazinoids

The paper identifies BxdA, a lactonase in maize root bacteria, which enables metabolic adaptation to benzoxazinoids, enhancing bacterial growth under carbon limitation.

Strain-dependent induction of primary bile acid 7-dehydroxylation by cholic acid

This study shows that CA induces 7-dehydroxylation of CDCA and UDCA by C. scindens, but not by E. muris, indicating strain-dependent regulation of bai genes.

Compartmentalization of intestinal bacteria by hepatic ILC3s prevents infections after surgery

The paper shows that intestinal bacteria cause surgical infections and that hepatic ILC3s prevent their translocation, highlighting the role of controlled commensalism in preventing post-surgical infections.

Antibodies set boundaries limiting microbial metabolite penetration and the resultant mammalian host response

The paper develops a model to distinguish microbial and host metabolites using stable isotope tracing and shows that antibodies limit microbial metabolite penetration into host tissues.
