Abstract:
:The adherence of Actinomyces naeslundii to human buccal mucosa is mediated by specific interactions between the bacterial cell surface fimbriae and complementary beta-linked galactoside receptors on the epithelial cell surface. The buccal mucosa and the bacteria that colonize its surface are constantly bathed in saliva. Several salivary components are thought to play an important role in modulating adhesive interactions between oral bacteria and the buccal epithelium. We have observed that pretreatment of isolated buccal epithelial cells (BEC) with human parotid saliva increased the attachment of three different strains of A. naeslundii. By employing affinity chromatography, ion-exchange and high-pressure liquid chromatographic techniques we have isolated a 180 kDa A. naeslundii-binding salivary glycoprotein (An-SPG). This salivary glycoprotein was capable of mediating separate but specific binding interactions with A. naeslundii and BEC. Pretreatment of BEC with increasing amounts of An-SGP resulted in a corresponding increase in the attachment of A. naeslundii. The adherence of A. naeslundii to An-SGP-coated BEC is sensitive to the same inhibitors previously shown to block adherence of A. naeslundii to uncoated BEC, namely lactose- and galactosyl-binding lectins. When a solubilized extract of freshly isolated and washed BEC was reacted on a Western blot with antibodies to An-SGP, a prominent 180 kDa immunoreactive band was detected. Furthermore, the immunoreactive component was demonstrated on the BEC surface when assayed by immunofluorescence using An-SGP-specific antibodies, suggesting that An-SGP or a protein structurally and immunologically identical to the isolated glycoprotein is present on BEC.
