Bradykinin (BK) is produced and acts at the site of injury and inflammation. In the CNS, migration of microglia toward the lesion site plays an important role pathologically. In the present study, we investigated the effect of BK on microglial migration. Increased motility of cultured microglia was mimicked by B1 receptor agonists and markedly inhibited by(More)
Leukotrienes B4, C4, D4 and E4, together with five monohydroxyeicosatetraenoic acids, were isolated after incubation of chopped rat brain tissue with ionophore A23187. The monohydroxyeicosatetraenoic acids were 5-hydroxy-6,8,11,14-eicosatetraenoic acid, 9-hydroxy-5,7,11,14-eicosatetraenoic acid, 11-hydroxy-5,8,12,14-eicosatetraenoic acid,(More)
The regional distribution of ionophore A23187-induced synthesis of leukotrienes and mono-hydroxyeicosatetraenoic acids in the rat brain in vitro was investigated. Pronounced differences in leukotriene C4 formation were observed, with the highest synthetic capacity in the hypothalamus. The formation of leukotriene C4 was about 12-times higher in the(More)
