Dopamine D1 receptors have subcellular distributions conducive to interactions with prodynorphin in the rat nucleus accumbens shell.

Activation of dopamine (DA) D1 receptors (D1Rs) in the nucleus accumbens (Acb) markedly affects the levels of prodynorphin, the precursor of aversion-associated dynorphin peptides. The location of prodynorphin, specifically as related to the dopaminergic inputs and D1Rs in the Acb, is fundamental for establishing the physiologically relevant sites. To… CONTINUE READING
