Thrilled to share that our study on how the pcnB gene sustains Shigella virulence is now published in PLOS Pathogens: journals.plos.org/plospathogen...

In short: pcnB ➝increased virulence-plasmid replication ➝ elevated T3SS expression ➝ enhanced invasion/spread within the intestinal epithelium.
The pcnB gene sustains Shigella flexneri virulence
Author summary Bacterial infections represent a major global threat. Understanding the genetic determinants promoting infections is crucial to overcome this threat. Shigella is an intracellular bacter...

Finally out! A small screen helps understand a little more about how E. coli regulates major transporters, and reveals how caffeine induces phenotypical antibiotic resistance. Huge thanks to collab @andrenmateus.bsky.social (Umeå) and Christian L. Müller (Munich)!

New preprint out: www.biorxiv.org/content/10.1...
We followed up on our recent Nature Genetics paper mapping Shigella colonization in intestinal organoids with a deep dive into one of the screen hits: pcnB.

Our latest work combines human gut epithelial #organoid culture with experimental #Shigella #infections, transposon mutagenesis, and statistical modeling. This has led to the mapping of the comprehensive geneset that drives Shigella epithelial colonization.

So happy to see the first paper on research from the lab out! Just a review for now, but it gives an idea of the avenues we are exploring.
As we start exploring this unique system of O-glycosylation in Bacteroidota species, we have reviewed the current state-of-the-art and offer some ideas on the directions we want to take. #glycotime doi.org/10.1002/2211...
