These macromolecular organelles are composed of protein polymers and can appear as regular, rod-like pili (or fimbriae), irregular, thin fibrils or indistinct structures. In gram-negative bacteria, many of these organelles are assembled by the chaperone-usher pathway (CUP).

fimbriae), irregular, thin fibrils or indistinct structures. In gram-negative bacteria, many of these organelles are assembled by the chaperone-usher pathway (CUP). The three essential components of this pathway are one or more pilin subunits capable of polymerization, a periplasmic chaperone that catalyzes proper The P. aeruginosa Cup fimbriae constitute one class of appendages that facilitate the biofilm formation and assemble through chaperone/usher pathway . In P. aeruginosa PAO1, at least four Cup systems (CupA, B, C, and E) have been identified and vary in organizations and functions . Certain sequence motifs are typical of CUP fimbriae, including alternating hydrophobic residues at the C-terminus of their pilins (Dodson et al., 1993, Nishiyama et al., 2005, Nishiyama et al., 2008. Phagocytic cup formation is the second stage of the internalization.

2009). In contrast to Pseudomonas and UPEC, the Gram-positive Enterococci are nonmotile and, up until recently, were thought to possess no adhesive pili. 2010-03-12 Here, we report that intracellular c-di-GMP levels influence cupA-encoded fimbriae expression in Pseudomonas aeruginosa. In an autoaggregative P. aeruginosa small colony variant (SCV) CupA fimbriae and the intracellular c-di-GMP concentration were found to … Here, we report that intracellular c-di-GMP levels influence cupA-encoded fimbriae expression in Pseudomonas aeruginosa. In an autoaggregative P. aeruginosa small colony variant (SCV) CupA fimbriae and the intracellular c-di-GMP concentration were found to … 2018-03-08 Unlike CUP and Csg fimbriae, Type IV pili are still connected to the IM of the bacteria and can be retracted rapidly inside the bacteria. 2.2 Roles of fimbrial adhesins during typhoid fever In most studies, Salmonella fimbriae are involved during intestinal colonization (Althouse et 2017-06-12 Biofilm production is a key virulence factor that facilitates bacterial colonization on host surfaces and is regulated by complex pathways, including quorum sensing, that also control pigment production, among others. To limit colonization, epithelial cells, as part of the first line of defense, utilize a variety of antimicrobial peptides (AMPs) including defensins.

Fimbrial or nonfimbrial adhesins assembled by the bacterial chaperone-usher pathway have been demonstrated to play a key role in pathogenesis. Such an assembly mechanism has been exemplified in uropathogenic Escherichia coli strains with the Pap and the Fim systems. In Pseudomonas aeruginosa , three gene clusters ( cupA , cupB , and cupC ) encoding c haperone- u sher p athway components have Recently, a new Cup-fimbriae gene cluster, CupD, has been identified on the pathogenicity island, PAPI-I, present in P. aeruginosa strain PA14 (Mikkelsen et al., 2009).

Recently, we identified three P. aeruginosa gene clusters that were termed cup (chaperone-usher pathway) based on their sequence relatedness to the chaperone-usher fimbrial assembly pathway in other bacteria. The cupA gene cluster, but not the cupB or cupC cluster, is required for biofilm formation on abiotic surfaces.

Overexpression of this gene cluster results in increased biofilm formation and decreased motility as was observed for overexpression of the other Cup-fimbrial gene clusters Transcription of CupB/C fimbriae is repressed by the response regulator PDE RocR (PA3947) (282), while repression of CupD fimbriae requires the response regulator PDE PvrR (283). See the text for further explanation.
