Porphyromonas gingivalis Mfa1 fimbria putatively binds to TLR2 and induces both IL-6 and IL-8 production in human bronchial epithelial cells.

Biochemical and Biophysical Research Communications, 2021
Porphyromonas gingivalis (Pg) a major periodontal pathogen involved in periodontal disease development and progression. Moreover, Pg has two fimbriae surface proteins (FimA and Mfa1) that are genetically distinct and make-up the fimbrial shaft which in ...

A Major Fimbrilin Variant of Mfa1 Fimbriae in Porphyromonas gingivalis

Journal of Dental Research, 2015
The periodontal pathogen Porphyromonas gingivalis is known to express 2 distinct types of fimbriae: FimA and Mfa1 fimbriae. However, we previously reported that fimbria-like structures were found in a P. gingivalis strain in which neither FimA nor Mfa1 fimbriae were detected.

Expression of MFA1 and STE6 is sufficient for mating type-independent secretion of yeast a-factor, but not mating competence

Current Genetics, 1999
The yeast a-factor mating peptide and its transporter Ste6 are normally expressed only in MATa haploid cells. The a-factor is initially produced as a 36- or 38-residue peptide precursor and must undergo extensive post-translational processing to produce an active 12 amino-acid lipopeptide.

Localization and function of the accessory protein Mfa3 in Porphyromonas gingivalis Mfa1 fimbriae.

Molecular Oral Microbiology, 2013
SummaryThe fimbriae of Porphyromonas gingivalis, the causative agent of periodontitis, have been implicated in various aspects of pathogenicity, such as colonization, adhesion and aggregation. Porphyromonas gingivalis ATCC 33277 has two adhesins comprised of the FimA and Mfa1 fimbriae.

Mutational analysis of genes determining antagonism of Alcaligenes sp. strain MFA1 against the phytopathogenic fungus Fusarium oxysporum.

Canadian Journal of Microbiology, 1992
Alcaligenes sp. strain MFA1 inhibits microconidial germination and germination-tube elongation of Fusarium oxysporum f.sp. dianthi and reduces the severity of fusarium wilt of carnation, presumably as a result of its production of a siderophore (G.Y. Yuen and M.N. Schroth. 1986. Phytopathology, 76: 171–176).

Metabolic-reprogrammed MnO₂-Mg/Pt@BBF nanozyme disrupts biofilm cohesion for enhanced chemodynamic therapy of periodontitis.

Dental Materials
OBJECTIVES To overcome the intrinsic incompatibility between dense periodontal biofilms and chemodynamic therapy (CDT), we developed a vacancy-engineered MnO₂ nanozyme that integrates redox-state programming, Mg²⁺-enabled endogenous H₂O₂ amplification ...
