Role of Mfa5 in Expression of Mfa1 Fimbriae in Porphyromonas gingivalis [PDF]

Journal of Dental Research, 2016
Fimbriae are protein-based filamentous appendages that protrude from the bacterial cell surface and facilitate host adhesion. Two types of fimbriae, FimA and Mfa1, of the periodontal pathogen Porphyromonas gingivalis are responsible for adherence to other bacteria and to host cells in the oral cavity.

Novel fimbrilin PGN_1808 in Porphyromonas gingivalis. [PDF]

PLoS ONE, 2017
Porphyromonas gingivalis, a periodontopathic gram-negative anaerobic bacterium, generally expresses two types of fimbriae, FimA and Mfa1. However, a novel potential fimbrilin, PGN_1808, in P.

Identification and Characterization of MFA1 , the Gene Encoding Candida albicans a -Factor Pheromone [PDF]

Eukaryotic Cell, 2007
ABSTRACT In the opaque state, MTL a and MTL α strains of Candida albicans are able to mate, and this mating is directed by a pheromone-mediated signaling process. We have used comparisons of genome sequences to identify a C. albicans

Porphyromonas gingivalis evasion of autophagy and intracellular killing by human myeloid dendritic cells involves DC-SIGN-TLR2 crosstalk. [PDF]

PLoS Pathogens, 2015
Signaling via pattern recognition receptors (PRRs) expressed on professional antigen presenting cells, such as dendritic cells (DCs), is crucial to the fate of engulfed microbes.

A Multiplex GPCR‐Mediated Peptide Tagging System for a Growing Yeast Synthetic Biology Toolbox

Helvetica Chimica Acta, Volume 106, Issue 12, December 2023., 2023
Abstract Straightforward methods for specifically detecting and quantifying proteins are essential for both basic and applied research and notably in synthetic biology. Previously we demonstrated that the yeast mating pathway could be hijacked to detect species‐specific fungal peptide pheromones using their corresponding mating GPCRs.

Proteome and immune responses of extracellular vesicles derived from macrophages infected with the periodontal pathogen Tannerella forsythia

Journal of Extracellular Vesicles, Volume 12, Issue 12, December 2023., 2023
Abstract Periodontitis is a chronic inflammatory disease caused by periodontal pathogens in subgingival plaque and is associated with systemic inflammatory diseases. Extracellular vesicles (EVs) released from host cells and pathogens carry a variety of biological molecules and are of interest for their role in disease progression and as diagnostic ...

Isolation, characterization, and fibroblast uptake of bacterial extracellular vesicles from Porphyromonas gingivalis strains

MicrobiologyOpen, Volume 12, Issue 5, October 2023., 2023
Bacterial extracellular vesicles (bEVs) from Porphyromonas gingivalis were isolated and characterized before uptake into oral fibroblast was visualized. bEVs from P. gingivalis displayed active gingipains that may have a role in the pathogenesis of periodontitis.

Phylogenetic diversity in fim and mfa gene clusters between Porphyromonas gingivalis and Porphyromonas gulae, as a potential cause of host specificity

Journal of Oral Microbiology, 2020
Background Periodontopathic bacteria Porphyromonas gingivalis in humans and Porphyromonas gulae in animals are phylogenetically close and commonly have FimA and Mfa1 fimbriae.

Exploring the genetic and functional diversity of Porphyromonas gingivalis long fimbriae

Molecular Oral Microbiology, Volume 38, Issue 5, Page 408-423, October 2023., 2023
Our work provides new PCR tools (i) to amplify and sequence every fimA gene of Porphyromonas gingivalis in its entire length including leader sequence and (ii) to check fimB, the fimbrial anchor gene, for functionality. Furthermore, transmission electron microscopy/scanning electron microscopy images give new insights into secondary structures formed ...
