Exploring the 3D Molecular Architecture of Escherichia coli Type 1 Pili
Journal of Molecular Biology, 2002An integrated approach combining information gained by Fourier transformation, linear Markham superposition (real space) and mass-per-length measurement by scanning transmission electron microscopy was used to analyze the helical structure of the rod-like type 1 pili expressed by uropathogenic Escherichia coli strain W3110.

Renal Scarring by Mannose-Sensitive Adhesin of Escherichia Coli Type 1 Pili
The Journal of Urology, 1998Most Escherichia coli isolates from patients with pyelonephritis possess both pap (mannose-resistant) pili and type 1 (mannose-sensitive) pili. In the experimental pyelonephritis model of rats, the mannose-sensitive-piliated strain caused severe renal scarring, whereas the mannose-resistant or nonpiliated strain did not.

Type 1 and P pili of uropathogenic Escherichia coli.
2014AbstractIn uropathogenic Escherichia coli (UPEC), type 1 pili (T1P) and P pili enable the bacterium to bind to host epithelial cells within the urinary tract, which can lead to a urinary tract infection. This chapter reviews the genetics, structure and functions of UPEC T1P and P pili. It also describes the mechanisms by which T1P and P pili contribute

Assembly of type 1 pili from Escherichia coli is mediated by FimC, a periplasmic chaperone (assembly factor) consisting of two immunoglobulin-like domains. FimC is assumed to recognize the individual pilus subunits in the periplasm mainly via their conserved C-terminal segments and to deliver the subunits to an assembly platform in the outer membrane ...

We compared the degree to which Escherichia coli phase variants which do (T1P+ E. coli) or do not (T1P- E. coli) express type 1 pili (T1P) stimulate human polymorphonuclear leukocyte (PMN) oxidative activity. Unopsonized T1P+ E. coli stimulated the release of 0.20 to 0.24 nmol of H2O2 per 10(6) PMN per min and the consumption of 1.4 to 4.0 nmol of O2 ...

This chapter concentrates on what the author thinks are the essential features of Escherichia coli type 1 pili as models of host-pathogen interactions, gene regulation, supramolecular assembly, and receptor binding. The majority of E. coli strains fell into group 1, which had the structures that were to become known as type 1 pili.

Fifteen Minutes of fim : Control of Type 1 Pili Expression in E. coli
OMICS: A Journal of Integrative Biology, 2002Pili are used by Escherichia coli to attach to and invade mammalian tissues during host infection and colonization. Expression of type 1 pili, believed to act as virulence factors in urinary tract infections, is under control of the ' fim ...

Type 1 pili are extracellular supramolecular protein complexes required for the attachment of pathogenic E. coli strains to host cells. Hundreds to thousands of protein subunits are assembled within minutes in vivo and form filaments with unique kinetic stability against dissociation.

Summary:We have previously shown that attachment of the rabbit enteroadherent Escherichia coli, strain RDEC‐1, to ileal brush borders in vitro is mediated by both man‐nose‐resistant, AF/R1 pili and mannose‐sensitive, type 1 pili. Because the role of type 1, somatic pili as adhesins that mediate bacterial enteroadherence in vivo remains controversial ...

Adherence of Escherichia coli to uroepithelial cells is an important step in the pathogenesis of urinary tract infection. The process is frequently mediated by pili which undergo phase variation in response to changes in environmental growth conditions in vitro.
