Specific interactions between Porphyromonas gingivalis fimbriae and human extracellular matrix proteins. [PDF]

FEMS Microbiology Letters, 1999
The interactions of the extracellular matrix (ECM) proteins (laminin, elastin, fibronectin, type I collagen, thrombospondin and vitronectin) with the fimbriae of Porphyromonas gingivalis were analyzed based on surface plasmon resonance (SPR) spectroscopy using a biomolecular interaction analyzing system (BIAcore). The BIAcore profiles demonstrated that

Suppression of Salmonella enterica serovar Enteritidis excretion by intraocular vaccination with fimbriae proteins incorporated in liposomes.

Developmental & Comparative Immunology, 2004
Liposome-associated fimbriae antigens (SEF14 and SEF21) were prepared for intraocular immunization to seek protective efficacy for intestinal infection with Salmonella enterica serovar Enteritidis. Chickens were immunized intraocularly with the antigens at 8 and 10 weeks of age.

Inhibitory effects of Porphyromonas gingivalis fimbriae on interactions between extracellular matrix proteins and cellular integrins.

Microbes and Infection, 2005
Porphyromonas gingivalis is a predominant periodontal pathogen, whose fimbriae are considered to be a major virulence factor, especially for bacterial adherence and invasion of host cells. In the present study, we investigated the influence of fimbriae on the interactions between alphavbeta3- and alpha5beta1-integrins and their ligand extracellular ...

Secretion of type-1-fimbriae binding proteins from human neutrophil granulocytes

Inflammation, 1996
Granule matrix proteins secreted from human neutrophils after ionomycin stimulation were separated by SDS-PAGE, blotted onto a polyvinylidene diflouride (PVDF) membrane and overlaid with the mannose-binding lectin concanavalin A (Con A) or Escherichia coli bacteria exposing type-I-fimbriae.

Formulation and characterisation of Bordetella pertussis fimbriae as novel carrier proteins for Hib conjugate vaccines.

Vaccine, 2001
Haemophilus influenzae type b (Hib) capsular polysaccharide (polyribosylribitol phosphate, PRP) is the active component of conjugate vaccines that have proven successful in preventing invasive Hib disease. Conjugation of PRP to a protein carrier greatly improves its immunogenicity providing protection in infants and subsequent antibody maturation upon ...

Binding of Enterobacterial Fimbria to Proteins of Basement Membranes and Connective Tissue — A Novel Function for Fimbriae

1991
Fimbriae are important virulence factors in a number of enterobacterial infections. It is generally thought that they increase the pathogenic potential of bacteria by mediating adherence to glycoconjugates of host epithelia, thus giving resistance to mechanical clearance defense systems of the body.

Cloning and sequence analysis of the fimbriae associated protein (fap) gene fromActinobacillus actinomycetemcomitans

Microbial Pathogenesis, 1997
Fimbrial-associated protein, an attachment factor of Actinobacillus actinomycetemcomitans, was genetically analysed by cloning. The plasmid obtained was found to harbor a 1.7kb fragment which contained a 228bp open reading frame encoding 76 amino acids (7.970kDa).

Molecular Characterization of Low‐Molecular‐Weight Component Protein, Flp, in Actinobacillus actinomycetemcomitans Fimbriae

Microbiology and Immunology, 1998
AbstractFimbriae preparation from Actinobacillus actinomycetemcomitans was found to contain an abundant low‐molecular‐weight protein (termed Flp) with an apparent molecular mass of approximately 6.5 kDa, in addition to a small amount of 54‐kDa protein.

Preparation and evaluation of recombinant pyolysin, fimbriae E and HtaA based protein vaccines against Trueperella pyogenes

Veterinary Microbiology, 2023
Trueperella pyogenes (T. pyogenes) could cause zoonotic disease in various mammals, resulting in significant economic losses. Due to the lack of effective vaccine and the emergence of bacterial resistance, there is a big need for new and improved vaccines.

Investigation of minor components of Escherichia coli Type 1 Fimbriae: protein chemical and immunological aspects

Microbial Pathogenesis, 1988
Three minor components of type 1 fimbriae, FimF, FimG and FimH have been characterized. These proteins are integrated in the fimbrial structure; are responsible for the adhesive properties of the fimbriae but are not necessary for the production of fimbriae.
