Puhar Lab
@lab-puhar.bsky.social
We study gut bacteria and the immune response to infection with a focus on the danger signal extracellular ATP. We particularly like Shigella and E. coli. Located at Queen's University Belfast, UK and Umeå University, Sweden.
It was great! Thanks to all presenters and attendees for sharing their research!

Very interesting new protective response in live (!) neutrophils against bacterial infection:
Benoit Marteyn@marteynlab.bsky.social · 9mo agoThrilled to share that neutrophils produce extra long fibrillar components named proteoglycofili or PGF. PGF are released by living neutrophils and do not contain DNA. They might look like NETs but are not NETs… www.cell.com/cell-reports...

Our first effort exploring gut bacteria-extracellular ATP interactions is published! We show that eATP rewires gene expression and physiology in harmless and pathogenic bacteria, impacting production of bioactive metabolites, antimicrobial sensitivity, and virulence.
