Investigation of fimH Single Nucleotide Polymorphisms (C640T and T591A) in Uropathogenic E. coli Isolated from Patients with Urinary Tract Infections
Background: Urinary tract infections are one of the most frequent health problems and Uropathogenic Escherichia coli is the major pathogen resulting UTIs. The severity of UTIs is caused by the expression of a large range of virulence factors.In this study, we evaluated the allelic frequency fimH gene, in UPECs isolated from patients with UTIs. This study also aimed to determine the roles of C64...
متن کاملIn silico Study of Toll-Like Receptor 4 Binding Site of FimH from Uropathogenic Escherichia coli
Introduction : The innate immune system as the first line of defense against the pathogens recognizes pathogen-associated molecular patterns (PAMPs) by Toll-Like Receptors (TLRs). Interaction of bacterial PAMPs by TLRs results in activation of innate and acquired immunity. FimH adhesin, a minor component of type 1 fimbriae encoded by Uropathogenic Escherichia coli (UPEC) is a PAMP of TLR4 tha...
متن کاملVaccination with FimH adhesin protects cynomolgus monkeys from colonization and infection by uropathogenic Escherichia coli.
Escherichia coli FimH adhesin mediates binding to the bladder mucosa. In mice, a FimH vaccine protects against bacterial challenge. In this study, 4 monkeys were inoculated with 100 microgram of FimCH adhesin-chaperone complex mixed with MF59 adjuvant, and 4 monkeys were given adjuvant only intramuscularly. After 2 doses (day 0 and week 4), a booster at 48 weeks elicited a strong IgG antibody r...
متن کاملInhibition and Reversal of Microbial Attachment by an Antibody with Parasteric Activity against the FimH Adhesin of Uropathogenic E. coli
Attachment proteins from the surface of eukaryotic cells, bacteria and viruses are critical receptors in cell adhesion or signaling and are primary targets for the development of vaccines and therapeutic antibodies. It is proposed that the ligand-binding pocket in receptor proteins can shift between inactive and active conformations with weak and strong ligand-binding capability, respectively. ...
متن کاملUroplakin Ia is the urothelial receptor for uropathogenic Escherichia coli: evidence from in vitro FimH binding.
The binding of uropathogenic Escherichia coli to the urothelial surface is a crucial initial event for establishing urinary tract infection because it allows the bacteria to gain a foothold on the urothelial surface, thus preventing them from being removed by micturition. In addition, it triggers bacterial invasion as well as host urothelial defense. This binding is mediated by the FimH adhesin...
