Outline of Final Research Achievements

Periodontal disease caused by bacterial infection is usually associated with metabolic disease contained with dyslipidemia. It was an aim to clarify what kind of influence osteoclast came under by dyslipidemia.
Both hypolipidemic agent, statin and drug for treatment of osteoporosis, nitrogen-containing bisphosphonates suppressed acid activated Cl- currents using whole cell patch clamp on osteoclasts, meaning inhibition of extruding H+ and Cl- on resorbing bone. Number of osteoclasts was increased by stimulation with the ligands of TLR2 or TLR4 which are receptors of periodontal pathogens, and oxLDL which is receptor caused to dyslipidemia. The result suggested the possibility that bone resorption may be progressing when periodontitis and dyslipidemia are complication.
