Stimulation of interleukin-6 production in human dental pulp cells by peptidoglycans from Lactobacillus casei.

Interleukin-6 (IL-6), which is a multifunctional cytokine, has an important role in acute and chronic inflammation. The peptidoglycan (PG) was purified from Lactobacillus casei, which was a Gram-positive bacteria frequently isolated from deep carious lesions and suspected to be a pathogen of pulpitis. In this study, the effects of PG on the production of IL-6 in human dental pulp cells were examined. PG stimulated IL-6 production in a time- and dose-dependent manner. Reverse transcriptase-polymerase chain reaction experiments showed that the increase was dependent on the enhancement of IL-6 mRNA levels. These findings suggest that Gram-positive bacteria, such as L. casei, from carious lesions, might be involved in developing pulpitis through the stimulation of IL-6 production.[1]
