Phagocytic cup formation is the second stage of the internalization. The fimbriae are distinctly visualized with the RR-OsO 4 technique. Inset: a diagram illustrating the phagocytic cup formation as a consequence of actin polymerization and membrane extension due to the transient signals by the formation of adhesin-receptor complexes.

Three cup gene clusters (cupA-C), involved in the assembly of cell surface fimbriae, have been shown to be involved in biofilm formation by the P. aeruginosa strains PAO1 or PAK. In PA14 isolates, Three cup gene clusters (cupA-C), involved in the assembly of cell surface fimbriae, have been shown to be involved in biofilm formation by the P. aeruginosa strains PAO1 or PAK. In PA14 isolates, a fourth cluster, named cupD , was identified within a pathogenicity island, PAPI-I, and may contribute to the higher virulence of this strain. The networks covered in depth regulate processes such as the switch between acute and chronic virulence (GacS network), the Cup fimbriae (Roc network and Rcs/Pvr network), the aminoarabinose modification of lipopolysaccharide (a network involving the PhoQP and PmrBA TCSs), twitching motility and virulence (a network formed from the Chp chemosensory pathway and the FimS/AlgR TCS), and biofilm formation (Wsp chemosensory pathway). A fimbria (plural fimbriae, adjective fimbriate) is a Latin word that literally means "fringe." It is commonly used in science and medicine, with its meaning depending on the field of study or the context. aeruginosa CupA, CupB, CupC and CupD fimbriae have been shown to be involved in bacterial attachment and/or subsequent biofilm formation , , . Overexpression of each of the Cup gene clusters was shown to promote biofilm formation of P. aeruginosa. The large surface adhesin CdrA evidently also plays a role in P. In an autoaggregative P. aeruginosa small colony variant (SCV) CupA fimbriae and the intracellular c-di-GMP concentration were found to be enhanced as compared with the clonal wild-type.

Cup fimbriae

CS20 and other Class 1b fimbriae are assembled by the chaperone‐usher pathway (CUP), as are other fimbriae including Type 1 fimbriae and P‐fimbriae expressed by uropathogenic Escherichia coli (UPEC). termed cup for chaperone-usher pathways, which may be in- volved in the assembly of novel P. aeruginosa ﬁmbrial struc- tures that are radically dif ferent from the type IV pili (5, 38).

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).

The opportunistic pathogen Pseudomonas aeruginosa PA14 possesses four fimbrial cup clusters, which may confer the ability to adapt to different pneumoniae and Cup fimbriae of P. aeruginosa are positively regulated on the transcriptional level by c-di-GMP signaling. An entire regulatory circuit of c-di- GMP Jan 23, 2018 The fimbriae of the uterine tube, also known as fimbriae tubae, are small, fingerlike projections at the end of the fallopian tubes, through which Jul 7, 2015 ETEC-expressing CFA/I fimbriae of the ACP family and CS20 fimbriae of the CUP. We therefore hypothesized that CS2 fimbriae would exhibit Fimbrial.

Biofilm formation in Pseudomonas aeruginosa: fimbrial cup gene clusters are controlled by the transcriptional regulator MvaT.

Interestingly, the cup gene clusters are similar to the fimbrial gene clusters of other organisms in that they contain genes encoding an usher, a chaperone, and one or more fimbrial subunits. Strikingly, Northern blot analysis showed that in all three cases, only a transcript with a size corresponding to that of the first gene of each cluster, cupA1 , cupB1 , and cupC1 , could clearly be identified. CS20 and other Class 1b fimbriae are assembled by the chaperone‐usher pathway (CUP), as are other fimbriae including Type 1 fimbriae and P‐fimbriae expressed by uropathogenic Escherichia coli (UPEC). termed cup for chaperone-usher pathways, which may be in- volved in the assembly of novel P. aeruginosa ﬁmbrial struc- tures that are radically dif ferent from the type IV pili (5, 38).

Genes encoding fimbrial subunits are represented as black arrows, genes encoding periplasmic chaperones are represented as gray arrows, and genes encoding ushers are represented with striped arrows.

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.
