Expression of TRAIL and its receptors DR5 and DcR2 in orthodontic tooth movement
BACKGROUND: TRAIL is a transmembrane protein that induces apoptosis in various tissues including alveolar bone. Its in vitro expression can be activated by several methods, such as RANKL administration and cell scraping. Expression of TRAIL and its receptors DR5 and DcR2 was examined in osteoclast-like cells to analyze their effects on cell lifespan and to explore their role in orthodontic tooth movement. MATERIALS AND METHODS: Osteoclast-like cells
