Abstract
In unilaterally 6-hydroxydopamine-lesioned rats, potentiation of D1-ag onist-induced turning behavior by priming with L-DOPA was correlated w ith changes in striatal neuropeptide mRNA levels. In non-primed rats, administration of the D1-agonist SKF-38393 markedly increased dynorphi n and substance P mRNA levels in the lesioned striatum. Priming with L -DOPA dissociated the response of the two neuropeptides to the D1-agon ist, with higher dynorphin and reduced substance P mRNA levels. (C) 19 98 Elsevier Science B.V.
