title: Inhibiting effects of serotonin and serotonin antagonists on the migration of mononuclear leucocytes.
abstract: The effect of serotonin and the serotonin antagonists ketanserin, methiotepine and ICS-205-930 on the migration of leucocytes was studied by using the sealed capillary migration technique. The migration of mononuclear leucocytes was inhibited by serotonin at 10(-4) and 10(-6)-10(-10)mol/l. An inhibition of the mononuclear leucocyte migration was also caused by ICS-205-930 at 10(-4)mol/l, ketanserin at 10(-4) and 10(-8)-10(-10)mol/l and methiotepine at 10(-4) and 10(-6)-10(-8)mol/l. No inhibiting effects of serotonin or the serotonin antagonists were found on the migration of polymorphonuclear leucocytes. Thus, both serotonin and serotonin antagonists may inhibit mononuclear leucocyte migration.
