Dynamin2- and endothelial nitric oxide synthase–regulated invasion of bladder epithelial cells by uropathogenic Escherichia coli
Invasion of bladder epithelial cells by uropathogenic Escherichia coli (UPEC) contributes to antibiotic-resistant and recurrent urinary tract infections (UTIs), but this process is incompletely understood. In this paper, we provide evidence that the large guanosine triphosphatase dynamin2 and its partner, endothelial nitric oxide (NO) synthase (NOS [eNOS]), mediate bacterial entry. Overexpressi...
متن کاملHuman milk oligosaccharides protect bladder epithelial cells against uropathogenic Escherichia coli invasion and cytotoxicity.
The invasive pathogen uropathogenic Escherichia coli (UPEC) is the primary cause of urinary tract infections (UTIs). Recurrent infection that can progress to life-threatening renal failure has remained as a serious global health concern in infants. UPEC adheres to and invades bladder epithelial cells to establish infection. Studies have detected the presence of human milk oligosaccharides (HMOs...
متن کاملSuppression of bladder epithelial cytokine responses by uropathogenic Escherichia coli.
Urinary tract infections are most commonly caused by uropathogenic strains of Escherichia coli (UPEC), which invade superficial bladder epithelial cells via a type 1 pilus-dependent mechanism. Inside these epithelial cells, UPEC organisms multiply to high numbers to form intracellular bacterial communities, allowing them to avoid immune detection. Bladder epithelial cells produce interleukin-6 ...
متن کاملMolecular Characterization and Antimicrobial Resistance of Uropathogenic Escherichia coli
Background:Urinary Tract Infections (UTIs) are the most common infectious diseases in childhood. The Uropathogenic Escherichia coli (UPEC) strains account for as much as 80% of UTIs. Objective:From a clinical perspective, it is important to know which virulence factors and antibiotic resistance properties are present in UPEC strains in pediatrics. Therefore, this study was carried out...
متن کاملIntegrin-Mediated Host Cell Invasion by Type 1–Piliated Uropathogenic Escherichia coli
Uropathogenic Escherichia coli (UPEC), the primary causative agent of urinary tract infections, typically express filamentous adhesive organelles called type 1 pili that mediate both bacterial attachment to and invasion of bladder urothelial cells. Several host proteins have previously been identified as receptors for type 1 pili, but none have been conclusively shown to promote UPEC entry into...
