Epithelial cells and their neighbors. IV. Bacterial contributions to intestinal epithelial barrier integrity.
Mammalian intestinal surfaces are in constant and intimate contact with a vast consortium of indigenous commensal bacteria. As a result, gut epithelia have evolved an array of strategies for limiting bacterial invasion into deeper tissues, helping to preserve the mutually beneficial nature of intestinal host-microbial relationships. In this review, we discuss a growing body of evidence indicati...
متن کاملLoss of intestinal epithelial barrier function in Salmonella Enteritidis infection
Intestinal infection with Salmonella enterica serotype Enteritidis, a food-borne infection spread to humans especially through contaminated eggs and egg-products as well as undercooked contaminated fresh meat, is the most common cause of intestinal inflammation in the European Union. Enteritis caused by Salmonella Enteritidis is characterized by fever, diarrhoea and abdominal pain. The disrupti...
متن کاملMuc17 protects intestinal epithelial cells from enteroinvasive E. coli infection by promoting epithelial barrier integrity.
The membrane-bound mucin MUC17 (mouse homolog Muc3) is highly expressed on the apical surface of intestinal epithelia and is thought to play a role in epithelial restitution and protection. Therefore, we hypothesized that MUC17 has a role in protection of the intestinal mucosa against luminal pathogens. Human intestinal cell lines were transfected by electroporation (Caco-2 and HT 29/19A) and b...
متن کاملYersinia pseudotuberculosis disrupts intestinal barrier integrity through hematopoietic TLR-2 signaling.
Intestinal barrier function requires intricate cooperation between intestinal epithelial cells and immune cells. Enteropathogens are able to invade the intestinal lymphoid tissue known as Peyer's patches (PPs) and disrupt the integrity of the intestinal barrier. However, the underlying molecular mechanisms of this process are poorly understood. In mice infected with Yersinia pseudotuberculosis,...
متن کاملA Candidate Approach Implicates the Secreted Salmonella Effector Protein SpvB in P-Body Disassembly
P-bodies are dynamic aggregates of RNA and proteins involved in several post-transcriptional regulation processes. P-bodies have been shown to play important roles in regulating viral infection, whereas their interplay with bacterial pathogens, specifically intracellular bacteria that extensively manipulate host cell pathways, remains unknown. Here, we report that Salmonella infection induces P...
