Background: Numerous studies report dysfunctional dopaminergic and noradrenergic neurotransmission in the pathogenesis of schizophrenia. Dopamine beta-hydroxylase (DBH) is an intracellular enzyme catalyzing the conversion of dopamine to noradrenaline. Functional polymorphisms have been reported in the promoter region of DBH gene, including a 19 bp insertion/deletion polymorphism. The purpose of this study was to investigate whether there was an association between the functional polymorphism (DBH50-Ins/Del) and schizophrenia in a Han Chinese population. Methods: This polymorphism was genotyped in 221 first-episode schizophrenics, 360 chronic schizophrenics and 318 healthy controls using a case-control design. We assessed their psychopathology using the Positive and Negative …

Objective: In recent years, abnormal changes in the endocannabinoid system have been found in schizophrenia. The superior temporal gyrus (STG) is strongly implicated in the pathophysiology of schizophrenia, particularly with regards to auditory hallucinations. In this study, we investigated the binding density of cannabinoid CB1 receptors in the STG of schizophrenia patients compared to control subjects. Methods: Quantitative autoradiography was used to investigate the binding densities of [3H] SR141716A (a selective antagonist) and [3H]CP-55940 (an agonist) to the CB1 receptors in the STG. Post-mortem brain tissue was obtained from the NSW Tissue Resource Centre (Australia). Results: Contrasting to previous findings …

Phencyclidine (PCP), a non-competitive NMDA/glutamate receptor antagonist, is a psychotomimetic drug that produces a syndrome in normal humans that resembles schizophrenia. The present study investigated the mechanisms of PCP actions by examining the density of glutamate and muscarinic receptors in the rat brain 4 h after a single injection of PCP. We used receptor autoradiography and [3H]MK801, [3H]AMPA, [3H]pirenzepine and [3H]AFDX384 to target glutamate NMDA, glutamate AMPA and muscarinic M1 and M2 receptors, respectively. The major outcome from the present study was an overall decrease in levels of the glutamate AMPA receptor density (F = 14.5, d.f. = 1, p …
