This is an interesting paper! Starting with a really big screen to look for GPCR activation by microbes, and ending with a convincing story by which microbes make acetylcholine in the gut to promote IgA production, ultimately leading to better colonization. www.nature.com/articles/s41...

Unexpected side-effect: how common medications clear the way for pathogens CMFI's @lisamaierlab.bsky.social @unituebingen.bsky.social show in @nature.com: many non-antibiotics weaken the natural protective function of the intestine. Press release: www.cmfi.uni-tuebingen.de/en/news-even...
Scanning electron microscopy image of a gut bacterial community (1:1.000.000). These interacting microorganisms form an ecosystem that is vital to human health. Medications can severely disrupt this fragile balance – they eliminate beneficial bacteria and thereby promote the growth of harmful species.

Non-antibiotics disrupt colonization resistance against enteropathogens - Nature
Non-antibiotic drugs from a wide range of therapeutic classes can alter the ability of gut commensals to resist invasion by enteropathogens, a previously underappreciated side effect of such drugs.
