Breast milk isn't just nutrition – it delivers live bacterial strains that colonize the infant gut and persist for months.
Happy to share our new paper, where we used metagenomics to track bacterial strains between 195 mother-infant pairs over the first 6 months of life:

Assembly of the infant gut microbiome and resistome are linked to bacterial strains in mother’s milk - Nature Communications
Here, with metagenomic analyses on longitudinal samples collected from 195 mother-infant pairs, the authors show that the breast milk microbiome contributes to infant gut assembly through bacterial st...

Thrilled to share my work from the @jkagan1.bsky.social lab!
TLDR: O-acetylation and wall teichoic acid compete for space on S. aureus peptidoglycan. This competition regulates DNA release, and thus immune receptor activation, during infection!

Wall teichoic acid is required for DNA-triggered innate immune receptor activation by Staphylococcus aureus
Receptors that stimulate inflammation are commonly activated by ligands that are buried within microbial cells. The mechanisms that facilitate immunostimulatory ligand release from microbes during inf...

I’m excited to share our latest work! We challenge the widely thought notion that cohousing and cross-fostering can normalize the microbiomes of genetically distinct mice: www.cell.com/cell-reports... 🐁🦠🧬
Cohousing or cross-fostering followed by cohousing does not normalize the microbiomes of genetically distinct adult mice
Lietuvninkas et al. use state-of-the-art gnotobiotic approaches to investigate whether
cohousing or cross-fostering overpower the role of genetics in shaping the fecal bacterial
commensal population. ...

A major challenge in RNA delivery is overcoming poor loading efficiency into nanoparticles. F. Machinandiarena solves this by using "SSHELs", our particles inspired by bacterial spores, to deliver RNA specifically to HER2+ ovarian cancer cells.
