Gut metagenomes reveal interactions between dietary restriction, ageing and the microbiome in genetically diverse mice - Nature Microbiology

Using a cohort of nearly 1,000 genetically diverse mice undergoing dietary restriction over the lifespan, the authors reveal numerous insights into the interactions between the gut microbiome, host ge...

A human gut bacterium antagonizes neighboring bacteria by altering their protein-folding ability

Antagonism shapes microbiomes. Lim et al. identify a mechanism used by human gut commensals to antagonize related bacteria. The secreted effector Bte1 alters the protein-folding machinery of targeted ...

Forging the iron‐net: Towards a quantitative understanding of microbial communities via siderophore‐mediated interactions

Iron is a critical yet limited nutrient for microbial growth. To scavenge iron, most microbes produce siderophores—diverse small molecules with high iron affinities. Different siderophores are specif...

Gut microbiota regulates stress responsivity via the circadian system

Gut microbes are known to modulate stress responsivity and behavior. Tofani et al. demonstrate that such modulations occur via the circadian system. The oscillations in gut microbiota composition regu...
