BACKGROUND: Periodontitis is not only one of the most prevalent inflammatory diseases among adults, but also commonly linked to numerous systemic conditions including cardiovascular diseases, stroke, and diabetes. Although osteoclasts are responsible for the alveolar bone resorption during periodontitis pathogenesis, the development of pharmacological strategies targeting these cells has not been vastly fruitful. METHODS: Bone marrow macrophages were cultured in the presence of macrophage-colony stimulating factor (M-CSF) and receptor activator of nuclear factor κB ligand (RANKL) to examine the direct effect of acalabrutinib on osteoclastogenesis...

BACKGROUND: Human periodontal ligament fibroblasts (HPDLFs) represent the first line of defense against pathogens in the periodontal tissue. Porphyromonas gingivialis (P. gingivalis) has been known to be most strongly associated with periodontitis. MicroRNA (miR)-146a is involved in the inflammatory regulation of periodontitis. However, the regulatory mechanism of miR-146a on in P. gingivalis-induced inflammation response in HPDLFs was still unclear. OBJECTIVE: The aim of this study was to investigate whether miR-146a plays a key role in P...
