  • Title: Adherence of Porphyromonas gingivalis to gingival epithelial cells: modulation of bacterial protein expression.
    Author: Agnani G, Tricot-Doleux S, Du L, Bonnaure-Mallet M.
    Journal: Oral Microbiol Immunol; 2000 Feb; 15(1):48-52. PubMed ID: 11155164.
    Abstract:
    The protein profiles of Porphyromonas gingivalis (ATCC 33277 and W83) bound to KB gingival epithelial cells were analyzed by SDS-PAGE and immunoblotting. We found that a 51-kDa component was formed in bacteria that adhered to the KB cells, whereas 26- to 29-kDa bands were less intensive, in contrast to the protein profile of free bacteria. P. gingivalis ATCC 33277 incubated with protease-treated KB cells retained the profile of free bacteria. These results demonstrate the specificity of bacterial recognition of eukaryotic membrane components.
