The role of tissue-type plasminogen activator system in amphetamine-induced conditional place preference extinction and reinstatement

Bahi, Amine ; Kusnecov, Alexander ; Dreyer, Jean-Luc

Extracellular serine proteases of the plasminogen activator family (tissue-type plasminogen activator (tPA) and urokinase-type plasminogen activator (uPA) may modulate synaptic adhesion and associate with learning behavior. Psychostimulants strongly induce their expression in the mesolimbic dopaminergic pathway, but cocaine preferentially induces uPA, whereas morphine and amphetamine...

Overexpression of plasminogen activators in the nucleus accumbens enhances cocaine-, amphetamine- and morphine-induced reward and behavioral sensitization

Bahi, Amine ; Dreyer, Jean-Luc

In: Genes, Brain and Behavior, 2008, vol. 7, no. 2, p. 244 - 256

Urokinase-type plasminogen activator (uPA) and tissue-type plasminogen activator (tPA) are extracellular proteases that play a role in synaptic plasticity and remodeling. Psychostimulants induce both tPA and uPA in acute and chronic drug delivery, but cocaine induces preferentially uPA, whereas morphine and amphetamine induce preferentially tPA.
