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.

Organoider, miniatyrorgan som odlas från mänskliga stamceller, är mycket användbara i forskning. I framtiden kommer de ha en stor betydelse även inom transplantationsvården. #Organoid #UppsalaUniversitet #Forskning

Mast cell subsets respond uniquely to Salmonella infection. Read all about it in our latest paper in EJI. Another chapter in our deciphering of mast cell interactions with enterobacteria, driven by Chris von Beek. onlinelibrary.wiley.com/doi/10.1002/...

Such a rewarding collab it has been with our colleagues at #Novavax to dissect the MoA of their potent Matrix-M adjuvant. This project has really put the imaging skills of @erixoneriksson.bsky.social to the test. The fruits of this joint labour out now in NPJ Vaccines www.nature.com/articles/s41...

Alert! The abstract deadline for the Microbial Pathogenesis & Host Response meeting has been extended to July 7 meetings.cshl.edu/meetings.asp...

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. #Shigella #virulence #microsky

Thanks @sydneylmiles.bsky.social and @sergemostowylab.bsky.social for writing such a sharp and thoughtful editorial, which covers all the main points and potential caveats of our study published yesterday. www.nature.com/articles/s41...

Thanks @scilifelab.se for the highlight of our recently published study @natgenet.nature.com. Link to the full paper here: rdcu.be/eqGgf

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. Out @natgenet.nature.com: rdcu.be/eqGgf

I enjoyed this NPR story but thought it was a bit unclear regarding the origin of the name "Salmonella" and who should be credited with its discovery.

Congrats to our newly baked Dr. Christopher von Beek, who defended his thesis on #Mastcells and #bacterial #infection in stride. Hooray! Thanks a lot to faculty opponent Jean Marshall and committee members Sanna Koskiniemi, Cecilia Andersson and Stefan Roos for the high-level sparring.

Was great fun to have the emminent @lbarquist.bsky.social visit for the @scilifelab.se The Svedberg seminar this week. Few can explain computation and statistics so that even wetlab biologists get it, but here is one: www.utm.utoronto.ca/biology/peop... www.helmholtz-hiri.de/en/research/...

Been a fun and fruitful industry collab with R&D of @novavax.bsky.social, teasing apart the mechanism of action of the MatrixM adjuvans. With some superb live-cell imaging by our @erixoneriksson.bsky.social together with Behdad Zarnegar. Here the resulting preprint: www.biorxiv.org/content/10.1...
