| Research Abstract |
Periodontitis is a chronic inflammatory disease caused by infection of periodontopathic bacteriae, which induces alveolarbone resorption. The alveolar bone resorption is characterized by an increased osteoclastic bone resorption that exceeds the bone formation by osteoblasts. This study clarified that Wnt signaling, which is a critical regulator controlling cell proliferation, movement, differentiation, polarity, and morphogenesis, plays a role in the enhancement both the fusion process during osteoclast differentiation and the expression of osteoclastic bone resorption-related genes.
