Porphyromonas gingivalis lipopolysaccharide induces miR-146a without altering the production of inflammatory cytokines

► LPS from Porphyromonas gingivalis significantly upregulates miR-146a expression in monocytes. ► Changes of miR-146a expression did not alter the proinflammatory cytokine production. ► Role of miR-146a may be fine-tuning of TLR signalling.
