1 Bradykinin and thrombin stimulate release of arachidonic acid and formation of prostanoids in human periodontal ligament cells. Prostaglandins coagulation factor II, thrombin Homo sapiens
2 In the present study, the effect of bradykinin (BK) and thrombin, two inflammatory mediators, on prostanoid biosynthesis in human PDL-cells was investigated. Prostaglandins coagulation factor II, thrombin Homo sapiens
3 BK and BK-B2 receptor agonists as well as thrombin, but not BK-B1 receptor agonists, also significantly increased [3H] release in human PDL-cells prelabelled with [3H]-arachidonic acid, indicating that BK and thrombin stimulate prostanoid biosynthesis, at least partly, due to activation of phospholipase A2. Prostaglandins coagulation factor II, thrombin Homo sapiens
4 These data show that BK via BK-B2 receptors, as well as thrombin, have the capacity to stimulate arachidonic acid release and subsequent prostanoid biosynthesis in human PDL-cells and thus may be implicated in the tissue reactions involved in orthodontic tooth movement. Prostaglandins coagulation factor II, thrombin Homo sapiens
