Epithelium-intrinsic NAIP/NLRC4 inflammasome drives infected enterocyte expulsion to restrict Salmonella replication in the intestinal mucosa

ME Sellin, AA Müller, B Felmy, T Dolowschiak… - Cell host & …, 2014 - cell.com
The gut mucosal epithelium separates the host from the microbiota, but enteropathogens
such as Salmonella Typhimurium (S. Tm) can invade and breach this barrier. Defenses …
