| Research Abstract |
In the present study, I demonstrated that LPA stimulated the production of IL-6 and IL-8 via the activation of PLC and IP_3 receptor-mediated intracellular calcium release in human osteoblasts. In contrast, the present results underline the importance of mTOR kinase acting as regulator of OPG production in mouse stromal cells. Furthermore, these results underline the cascade leading to NGF production, suggesting that mouse osteoblastic cells secrete NGF through the suppression of NF_<-KB> nuclear translocation. If key signal cascade for these regulators of bone-metabolism can be elucidated, it can open the door for a new therapy for bone-destructive diseases by means of controlling these productions.
