Abstract excerpt
Chronic opiate exposure induces numerous neurochemical adaptations in the noradrenergic system, including upregulation of the cAMP-signaling pathway and increased expression of tyrosine hydroxylase (TH), the rate-limiting enzyme in catecholamine biosynthesis. These adaptations are thought to compensate for opiate-mediated neuronal inhibition but also contribute to physical dependence, including withdrawal after...
