pubmed:abstractText
Porphyromonas gingivalis (PG) is a micro-organism that is suggested to play an etiologic role in acute and chronic periodontitis. The present study was undertaken to evaluate the question whether PG is capable of inducing interleukin (IL)-1beta, IL-6, macrophage inflammatory protein (MIP)-2, and granulocyte-macrophage colony-stimulating factor (GM-CSF) production in macrophages. Furthermore, the effect of PG on the activation of macrophages by Escherichia coli-lipopolysaccharide (LPS) was studied. The cytokines were analyzed by detection of specific mRNA. The mRNA was amplified by RT-PCR and semi-quantitatively analyzed by high performance liquid chromatography and densitometrically, respectively. These studies demonstrate that LPS was more active than PG in inducing mRNA expression of IL-1beta, IL-6, MIP-2 and GM-CSF. Moreover, PG reduced the mRNA expression of the macrophages stimulated with LPS, especially the IL-1beta and IL-6 mRNA expression was decreased.
