Determinants of the Divergent Salmonella and Shigella Epithelial Colonization Strategies Resolved in Human Enteroids and Colonoids

P. Geiser, M. L. Di Martino, A. C. C. Lopes, A. Bergholtz, M. Sundbom, M. Skogar, W. Graf, D.-L. Webb, P. M. Hellstrom, J. Eriksson, M. E. Sellin

This study compares Salmonella and Shigella colonization strategies in human enteroids and colonoids, identifying distinct virulence factor modules that drive divergent infection kinetics and epithelial colonization patterns.

A Two-Step Activation Mechanism Enables Mast Cells to Differentiate their Response between Extracellular and Invasive Enterobacterial Infection

C. von Beek, A. Fahlgren, P. Geiser, M. L. Di Martino, O. Lindahl, G. I. Prensa, E. Mendez-Enriquez, J. Eriksson, J. Hallgren, M. Fällman, G. Pejler, M. E. Sellin

This study shows mast cells use a two-step activation mechanism to distinguish between extracellular and invasive bacterial infections, leading to different cytokine responses.

Gasdermin D is the only Gasdermin that provides non-redundant protection against acute Salmonella gut infection

S. A. Fattinger, L. Maurer, P. Geiser, U. Enz, S. Ganguillet, E. Gul, S. Kroon, B. Demarco, M. Furter, M. Barthel, P. Pelczar, F. Shao, P. Broz, M. E. Sellin, W.-D. Hardt

This study identifies Gasdermin D as the only Gasdermin providing non-redundant protection against acute Salmonella Typhimurium gut infection by restricting bacterial loads, controlling inflammation, and preventing epithelial disruption.
