Clozapine and other neuroleptic drugs antagonize the light-evoked suppression of melatonin biosynthesis in chick retina: involvement of the D4-like dopamine receptor

Abstract

The subtype of dopamine receptor mediating the suppressive effect of light on melatonin biosynthesis in chick retina was characterized pharmacologically. Acute exposure of animals to light during the dark phase of the light-dark cycle dramatically decreased melatonin levels and activity of serotonin N-acetyltransferase (NAT; a key regulatory enzyme in… (More)
