Research Abstract |
In the present study we investigated whether tissue plasminogen activator (tPA)-plasmin system was involved in the pathophysiology/pathogenesis of dopamine-related neuropsychiatric disorders, by using animal models for the diseases. Our findings suggest that tPA-plasmin may play a role in the development of methamphetamine dependence as well as methamphetamine-induced psychosis. Furthermore, it is indicated that the activation of dopamine D1 receptors leads to an increase in extracellular tPA activity and the dopamine D1 receptor-tPA signaling may play a role in memory formation.
