Salmonella spvC Gene Inhibits Pyroptosis and Intestinal Inflammation to Aggravate Systemic Infection in Mice.

ABSTRACT: Salmonella enterica serovar Typhimurium (S). Typhimurium is a primary foodborne pathogen infecting both humans and animals. Salmonella plasmid virulence C (spvC) gene is closely related to S. Typhimurium dissemination in mice, while the mechanisms remain to be fully elucidated. Pyroptosis, a gasdermin-mediated inflammatory cell death, plays a role in host defense against bacterial infection, whereas the effect of spvC on pyroptosis and its function in inflammatory injury induced by S. Typhimurium are rather limited. In our study, C57BL/6 mice and J774A.1 cells infected with S. Typhimurium wild-type strain SL1344, spvC deletion mutant, spvC K136A site-directed mutant, and complemented strain were used to investigate poten
