Recognition of immunoglobulin A1 by oral actinomyces and streptococcal lectins.
نویسندگان
چکیده
Actinomyces naeslundii and Streptococcus gordonii, oral bacteria that possess Gal/GalNAc- and sialic acid-reactive lectins, respectively, were adherent to immobilized secretory immunoglobulin A (IgA) and two IgA1 myeloma proteins but not to two IgA2 myeloma proteins. Apparently, O-linked oligosaccharides at the hinge region of the IgA1 heavy chain are receptors for lectin-mediated adhesion of these bacteria.

Structural and antigenic types of cell wall polysaccharides from viridans group streptococci with receptors for oral actinomyces and streptococcal lectins.
Lectin-mediated interactions between oral viridans group streptococci and actinomyces may play an important role in microbial colonization of the tooth surface. The presence of two host-like motifs, either GalNAc beta1-->3Gal (Gn) or Gal beta1-->3GalNAc (G), in the cell wall polysaccharides of five streptococcal strains accounts for the lactose-sensitive coaggregations of these bacteria with Ac...
متن کاملStreptococcal Receptor Polysaccharides: Recognition Molecules for Oral Biofilm Formation
BACKGROUND Strains of viridans group streptococci that initiate colonization of the human tooth surface typically coaggregate with each other and with Actinomyces naeslundii, another member of the developing biofilm community. These interactions generally involve adhesin-mediated recognition of streptococcal receptor polysaccharides (RPS). The objective of our studies is to understand the role ...
متن کاملSpecific and nonspecific inhibition of adhesion of oral actinomyces and streptococci to erythrocytes and polystyrene by caseinoglycopeptide derivatives.
Various caseinoglycopeptide derivatives prepared from mammalian milk were evaluated as inhibitors of hemagglutinations mediated by Actinomyces viscosus Ny1, Streptococcus sanguis OMZ9, and, for comparative purposes, plant lectins from Arachis hypogaea and Bauhinia purpurea. It was found that recognition of the beta-D-galactose-(1----3)-2-acetamido-2-deoxy-D-galactose carbohydrate chain by Actin...
متن کاملCommon antigens of streptococcal and nonstreptococcal oral bacteria: characterization of wall-associated protein and comparison with extracellular protein antigen.
A soluble wall-associated common protein (WAP) has been isolated from cell wall-extracted antigens of exponentially growing cells of Streptococcus sanguis OMZ9, two serotypes (a and e), of Streptococcus mutans and Actinomyces viscosus OMZ104. The WAP antigens from the different strains were obtained by chromatography on an anti-rabbit immunoglobulin column of sodium dodecyl sulfate-dissociated ...
متن کاملInhibition by cocoa extracts of biosynthesis of extracellular polysaccharide by human oral bacteria.
Extracts of defatted cocoa inhibited the biosynthesis of extracellular polysaccharide by both cell-free and cell-associated streptococcal glucosyltransferases, but did not affect growth or acid production. Both water-insoluble and water-soluble polysaccharide syntheses were inhibited, and the net result was a shift away from adherence-supportive polysaccharide. Inhibition was non-competitive wi...
