Site of naloxone-precipitated opiate withdrawal dissociates from that at which apomorphine reinitiates this phenomenon. 1978

R Schulz, and J Bläsig, and E Laschka, and A Herz

The site of action of naloxone to induce jumping in morphine tolerant/dependent rats appears to be dissociated from structures where apomorphine initiates its action to reinduce jumping in previously withdrawn animals. These findings suggest that dopaminergic pathways do not directly affect the neuronal circuit involved in withdrawal jumping behavior, but instead exert a facilitatory influence on neurons that become supersensitive during the state of withdrawal. Thus, an increased response to apomorphine during naloxone-precipitated opiate withdrawal does not necessarily imply a specific supersensitivity of the dopaminergic system.

D011957 Receptors, Opioid Cell membrane proteins that bind opioids and trigger intracellular changes which influence the behavior of cells. The endogenous ligands for opioid receptors in mammals include three families of peptides, the enkephalins, endorphins, and dynorphins. The receptor classes include mu, delta, and kappa receptors. Sigma receptors bind several psychoactive substances, including certain opioids, but their endogenous ligands are not known.
