Sodium fluoride, guanylimidodiphosphate, and the D1 dopamine receptor agonist SKF 38393 elicited a greater activation of adenylate cyclase in homagenates of caudate nucleus in schizophrenic than in nonschizophrenic subjects used as controls. Similarly, a greater activation of adenylate cyclase by sodium fluoride was observed in the nucleus accumbens of schizophrenics. These findings suggest that the coupling of dopamine D1 recognition sites with adenylate cyclase is more efficient in the brain of the schizophrenic, presumably because of an increased affinity of the G/F protein for guanosine 5'-triphosphate.
