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.

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.

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 ...

Assembly of type 1 pili in Escherichia coli
2001An extensive random mutagenesis study on the function of nine residues in the subunit binding site of FimC was conducted to evaluate the mol. mechanisms of subunit binding by FimC and the contribution of chaperone surface residues. Five plasmid libraries of FimC variants with amino acid replacements in one or two of the nine residues were constructed ...

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.

Preincubation of human polymorphonuclear leukocytes with free whole type 1 pili derived from Escherichia coli or with subunits of type 1 pili significantly augmented subsequent stimulation of cellular oxygen uptake by formyl-methionyl-leucyl-phenylalanine, concanavalin A, opsonized zymosan, or latex particles coated with whole type 1 pili.
