In the central nervous system, the opioid and non-opioid transmitter system jointly compete with multiple pathophysiological processes. The in vitro neuronal model of rat (Wistar) caudate putamen and reverse transcription-poly-merase chain reaction were used to examine the effects of neurotensin and/or morphine on the expression of mu or delt-opioid receptor mRNA. In the present study neurotensin (10 nmol/l) promoted but morphine (0.001 mmol/l) reduced mu or delt-opioid...
