Curli functional amyloid systems are phylogenetically widespread and display large diversity in operon and protein structure. [PDF]

open access: yesPLoS ONE, 2012
Escherichia coli and a few other members of the Enterobacteriales can produce functional amyloids known as curli. These extracellular fibrils are involved in biofilm formation and studies have shown that they may act as virulence factors during ...

Curli Biogenesis and Function [PDF]

open access: yesAnnual Review of Microbiology, 2006
Curli are the major proteinaceous component of a complex extracellular matrix produced by many Enterobacteriaceae. Curli were first discovered in the late 1980s on Escherichia coli strains that caused bovine mastitis, and have since been implicated in many physiological and pathogenic processes of E. coli and Salmonella spp.

Regulation by cyclic di-GMP attenuates dynamics and enhances robustness of bimodal curli gene activation in Escherichia coli.

open access: yesPLoS Genetics, 2023
Curli amyloid fibers are a major constituent of the extracellular biofilm matrix formed by bacteria of the Enterobacteriaceae family. Within Escherichia coli biofilms, curli gene expression is limited to a subpopulation of bacteria, leading to ...

The Congo red derivative FSB binds to curli amyloid fibers and specifically stains curliated E. coli. [PDF]

open access: yesPLoS ONE, 2018
The Congo red derivative (E,E)-1-fluoro-2,5-bis(3-hydroxycarbonyl-4-hydroxy) styrylbenzene (FSB) specifically stains the functional amyloid curli in Escherichia coli biofilms.

Microbiome or Infections: Amyloid-Containing Biofilms as a Trigger for Complex Human Diseases

open access: yesFrontiers in Immunology, 2021
The human microbiota is the community of microorganisms that live upon or within their human host. The microbiota consists of various microorganisms including bacteria, fungi, viruses, and archaea; the gut microbiota is comprised mostly of bacteria. Many

Discovery of New Genes Involved in Curli Production by a Uropathogenic Escherichia coli Strain from the Highly Virulent O45:K1:H7 Lineage

open access: yesmBio, 2018
Curli are bacterial surface-associated amyloid fibers that bind to the dye Congo red (CR) and facilitate uropathogenic Escherichia coli (UPEC) biofilm formation and protection against host innate defenses.

Curli of Uropathogenic Escherichia coli Enhance Urinary Tract Colonization as a Fitness Factor

open access: yesFrontiers in Microbiology, 2019
Curli, a type of fimbriae widely distributed in uropathogenic Escherichia coli (UPEC), are involved in adhesion to human bladder cell surfaces and biofilm development. The role of UPEC curli was evaluated in a murine model of urinary tract infection. The

Assembly and substrate recognition of curli biogenesis system

open access: yesNature Communications, 2020
A major component of bacterial biofilms is curli amyloid fibrils secreted by the curli biogenesis system. Here authors use cryo-EM to visualize the secretion channel complexes (CsgF-CsgG) with and without the curli substrate and provide insights into ...

Fabrication of Curli Fiber-PEDOT:PSS Biomaterials with Tunable Self-Healing, Mechanical, and Electrical Properties

open access: yes, 2022
Poly­(3,4-ethylenedioxythiophene) polystyrenesulfonate (PEDOT:PSS) is a highly conductive, easily processable, self-healing polymer. It has been shown to be useful in bioelectronic applications, for instance, as a biointerfacing layer for studying brain ...

Differential regulatory control of curli (csg) gene expression in Salmonella enterica serovar Typhi requires more than a functional CsgD regulator

open access: yesScientific Reports, 2023
The human-specific Salmonella enterica serovar Typhi (S. Typhi) causes typhoid fever, a systemic disease with no known reservoir. Curli fimbriae are major components of biofilm produced by Salmonella and are encoded by the csg gene cluster (csgBAC and ...
