| Research Abstract |
The aim of this study was to clarify the role of uPAR on the LPS-indeuced bone resorption. We found that LPS induced the expression of uPAR in osteoclasts, but LPS did not inducethe expression of uPAR in osteoblasts. We also found that the reduction of uPAR attenuated the LPS-induced NF-kB activation, and uPAR overexpression promoted the LPS- induced NF-kB activity. In addition, we demonstrated that the binding of uPA/uPAR regulates the LPS-induced NF-kB activation and osteoclast differentiation. Moreover, we found that uPAR is associated with LPS-induced RANKL expression in osteoblasts.
