| Outline of Final Research Achievements |
The osteocytes that are the most abundant in bone tissue control osteoclastic bone resorption through the expression of the receptor activator of NF-κB ligand (RANKL). We reported that sympathetic regulation of osteoblasts and osteoclasts. In this study, we examined whether osteocytes are involved in sympathetic regulation of bone metabolism. First, we confirmed that sympathetic neurons and osteocyte were functionally connected via α adrenergic receptor and noradrenaline influences RANKL production by osteocytes via the α adrenergic receptor. Thus, we suggested that the sympathetic nervous system directly controls RANKL expression of osteocytes and influences bone metabolism.
