TL;DR: Intestinal group 3 innate lymphoid cells have memory-like properties after bacterial infection that contribute to long-term mucosal defense, and these “trained” ILC3s (Tr-ILC3s) showed superior activation and controlled infection better than “naïve’ I LC3s after pathogen rechallenge.

TL;DR: A novel innate immune response to an enteropathogen is unveiled, which implicates gp38+ stromal cells and locks intestinal villus invasion, but favors colitis.

TL;DR: Results show that Listeria, upon docking onto its luminally accessible receptor Ecad, hijacks its recycling pathway to be transferred by transcytosis across goblet cells.

TL;DR: Endovascular listeriosis is a rare but severe infection that manifests as vascular infections and endocarditis, mostly in older patients with vascular or cardiac valve prosthetic devices and co-morbidities, requiring prompt recognition and treatment.

TL;DR: This article showed that the immaturity of the neonatal intestinal microbiota leads to low resistance to Group B streptococcus intestinal colonization and permissiveness of the gut-vascular barrier, and the age-dependent but microbiotaindependent Wnt activity in intestinal and choroid plexus epithelia results in a lower degree of cell-cell junctions' polarization, which favors bacterial translocation.
