The effect of bradykinin on osteoclastogenesis in vitro and LPS-induced bone resorption in vivo

Abstract

Besides the classical action of the kallikrein-kinin system (KKS) in the modulation of the vascular tonus, this system is also involved in different pathologies, some of them being inflammatory in nature. Inflammatory processes in the vicinity of the skeleton generally leads to bone loss, and in vitro models demonstrate that kinins may participate of inflammatory bone resorption by activating the B1 and B2 kinin receptors. In contrast with these findings, some in vivo studies demonstrate an inhibitory role of the KKS on bone resorption and osteoclast differentiation. Since several drugs having the KKS as target are available in the market, the knowledge about the mechanisms underlying the role of kinins on bone resorption is very important to predict side effects and develop new drugs. Therefore, the aim of the present project is to analyze the role of kinins on LPS-induced bone resorption in vivo and the role of kinins on osteoclastogenesis in vitro. (AU)
