:e0039025.
PMID: 39998229
Importance: The gut-adapted bacterium Typhimurium causes inflammatory diarrhea via a process that involves active invasion of intestinal epithelial cells, secretion of inflammatory molecules, and recruitment of immune cells. Although bacterial...

PMID: 35345596
The multilayered meninges surrounding the brain and spinal cord harbor distinct immune cell populations with prominent roles in health and diseases. Here we present an optimized protocol for RNA fluorescence...

Cell Host Microbe
. 2021 Jul;
29(8):1316-1332.e12.
PMID: 34237247
Intracellular bacterial pathogens inject effector proteins to hijack host cellular processes and promote their survival and proliferation. To systematically map effector-host protein-protein interactions (PPIs) during infection, we generated a library...

Cell Host Microbe
. 2021 May;
29(7):1177-1185.e6.
PMID: 34043959
Persistent and intermittent fecal shedding, hallmarks of Salmonella infections, are important for fecal-oral transmission. In the intestine, Salmonella enterica serovar Typhimurium (STm) actively invades intestinal epithelial cells (IECs) and survives...

PLoS Pathog
. 2021 Mar;
17(3):e1009395.
PMID: 33684179
The mammalian immune system is constantly challenged by signals from both pathogenic and non-pathogenic microbes. Many of these non-pathogenic microbes have pathogenic potential if the immune system is compromised. The...

PMID: 31370104
Salmonella enterica serovar Typhimurium is a facultative intracellular pathogen that invades the intestinal epithelium. Following invasion of epithelial cells, Salmonella survives and replicates within two distinct intracellular niches. While all...
