摘要: The c-fos and junB immediate early genes (IEGs) were induced in neurons of the medial ventral striatum following administration morphine. striatal induction mRNA Fos protein was blocked by naloxone, D1 dopamine (DA) receptor antagonists, SCH23390 SCH39166, N-methyl-D-aspartate (NMDA) glutamate antagonist, MK801. MK801 did not block morphine septum. Since pattern nucleus accumbens similar to that observed with cocaine amphetamine [2,18,45,51], these data support current concepts limbic are among brain regions mediate drug abuse [9,10,23,27,49]. If it is true receptors activate CRE (cyclase response element) NMDA SRE (serum promoter [1], then this suggests serial activation mu opiate, on different required induce Moreover, concurrent for neurons. simultaneous should lead long-term changes gene expression might also be involved circuits could form basis 'memories' relating prior exposure addictive drugs.
