Transcriptional Activation of mRNA of Intercellular Adhesion Molecule 1 and Induction of Its Cell Surface Expression in Normal Human Gingival Fibroblasts by Mycoplasma salivarium and Mycoplasma fermentans

摘要

Lipoproteins in the cell membranes of both Mycoplasma salivarium and Mycoplasma fermentans were demonstrated to trigger the transcription of intercellular adhesion molecule-1 mRNA in normal fibroblasts isolated from human gingival tissue and to induce its cell surface expression by a mechanism distinct from that of Escherichia coli lipopolysaccharide. The lipid moiety of the lipoproteins was suggested to play a key role in the expression of the activity.
