Preventing Pseudomonas aeruginosa and Chromobacterium violaceum infections by anti-adhesion-active components of edible seeds
BACKGROUND Pseudomonas aeruginosa adhesion to animal/human cells for infection establishment involves adhesive proteins, including its galactose- and fucose-binding lectins PA-IL (LecA) and PA-IIL (LecB). The lectin binding to the target-cell receptors may be blocked by compatible glycans that compete with those of the receptors, functioning as anti-adhesion glycodecoys. The anti-adhesion treat...
متن کاملThe Pseudomonas aeruginosa lectins PA-IL and PA-IIL are controlled by quorum sensing and by RpoS.
In Pseudomonas aeruginosa, many exoproduct virulence determinants are regulated via a hierarchical quorum-sensing cascade involving the transcriptional regulators LasR and RhlR and their cognate activators, N-(3-oxododecanoyl)-L-homoserine lactone (3O-C12-HSL) and N-butanoyl-L-homoserine lactone (C4-HSL). In this paper, we demonstrate that the cytotoxic lectins PA-IL and PA-IIL are regulated vi...
متن کاملStructural basis for the interaction between human milk oligosaccharides and the bacterial lectin PA-IIL of Pseudomonas aeruginosa.
One of the mechanisms contributing to the protection by breast-feeding of the newborn against enteric diseases is related to the ability of human milk oligosaccharides to prevent the attachment of pathogenic bacteria to the duodenual epithelium. Indeed, a variety of fucosylated oligosaccharides, specific to human milk, form part of the innate immune system. In the present study, we demonstrate ...
متن کاملStructural basis for mannose recognition by a lectin from opportunistic bacteria Burkholderia cenocepacia.
Chronic colonization of the lungs by opportunist bacteria such as Pseudomonas aeruginosa and members of the Bcc (Burkholderia cepacia complex) is the major cause of morbidity and mortality among CF (cystic fibrosis) patients. PA-IIL (lecB gene), a soluble lectin from Ps. aeruginosa, has been the subject of much interest because of its very strong affinity for fucose. Orthologues have been ident...
متن کاملBlocking Pseudomonas Aeruginosa, Chromobacterium Violaceum, and Ralstonia Solanacearum Adhesion by Fruit Glycans
P. aeruginosa produces two lectins: PA-IL (LecA) (that bind galactose [Gal] and L-arabinose [Ara]), and PA-IIL (LecB) (that binds fucose [Fuc] > mannose [Man] and fructose [Fru]) [5,6]. These lectins contribute to the pathogens adhesion to target cells [7] and amplify the destructive effects of their accompanying virulence factors on those cells [8]. They also contribute to the pathogen auto-ag...
