bolA gene involved in curli amyloids and fimbriae production in E. coli: exploring pathways to inhibit biofilm and amyloid formation

Journal of Biological Research - Thessaloniki, 2020
Background Biofilm formation is a complex phenomenon of bacterial cells, involved in several human infections. Its formation is regulated and controlled by several protein factors.

Cryptic variation within and among islands in the ultraviolet reflectance of lizard throat coloration

Journal of Animal Ecology, EarlyView.
Identifying the existence of ‘cryptic’ morphs is critical in animal ecology for providing a basis for accurately testing links between phenotype and environment. This study identifies the existence of previously undocumented variation in UV reflectance in Aegean wall lizards that likely has novel behavioural and evolutionary implications within this ...

Artistic simulation of curly hair [PDF]

Proceedings of the 12th ACM SIGGRAPH/Eurographics Symposium on Computer Animation, 2013
Artistic simulation of hair presents many challenges - ranging from incorporating artistic control to dealing with extreme motions of characters. Additionally, in a production environment, the simulation needs to be fast and results need to be usable "out of the box" (without extensive parameter modifications) in order to produce content efficiently ...

Purification of the Bacterial Amyloid “Curli” from Salmonella enterica Serovar Typhimurium and Detection of Curli from Infected Host Tissues

Bio-Protocol, 2022
Microbiologists are learning to appreciate the importance of “functional amyloids” that are produced by numerous bacterial species and have impacts beyond the microbial world. These structures are used by bacteria to link together, presumably to increase

Archaeal Genes Code for GGDEF Domain Proteins With Diguanylate Cyclase Activity

Molecular Microbiology, EarlyView.
A biofilm‐like mode of growth is hypothesized to be required for the emergence of cellular life. Occurrence of common biofilm gene products in current Bacteria and Archaea is an indication for their previous presence in the last universal common ancestor LUCA and perhaps even in the first universal common ancestor FUCA.

A gut bacterial amyloid promotes α-synuclein aggregation and motor impairment in mice

eLife, 2020
Amyloids are a class of protein with unique self-aggregation properties, and their aberrant accumulation can lead to cellular dysfunctions associated with neurodegenerative diseases. While genetic and environmental factors can influence amyloid formation,

Bacterial curli protein promotes the conversion of PAP248-286 into the amyloid SEVI: cross-seeding of dissimilar amyloid sequences [PDF]

PeerJ, 2013
Fragments of prostatic acid phosphatase (PAP248-286) in human semen dramatically increase HIV infection efficiency by increasing virus adhesion to target cells.

A semi high-throughput method for real-time monitoring of curli producing Salmonella biofilms on air-solid interfaces

Biofilm, 2021
Biofilms enable bacteria to colonize numerous ecological niches. Bacteria within a biofilm are protected by the extracellular matrix (ECM), of which the fibril-forming amyloid protein curli and polysaccharide cellulose are major components in members of ...

233 nm far‐UV‐C radiation for biofilm inactivation

Photochemistry and Photobiology, EarlyView.
Based on tests to assess biofilm formation potential (crystal violet staining, color of colonies grown on Congo red agar and calcofluor agar), three bacterial genera/species/strains (Staphylococcus (S.) epidermidis, S. aureus, Pseudomonas (P.) aeruginosa) were selected for analysis of their biofilm matrix composition.

Characterization of curli a production on living bacterial surfaces by scanning probe microscopy

, 2018
Curli are adhesive surface fibers produced by many Enterobacteriaceae, such as Escherichia coli and Salmonella enterica. They are implicated in bacterial attachment and invasion to epithelial cells.
