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 …

The serotonergic system has close interactions with the dopaminergic system and is strongly implicated in the pathophysiological mechanisms and therapeutic paradigms of Parkinson’s disease (PD). This study aims to investigate regional changes in 5-hydroxytryptamine (5-HT) 2A receptors in the rat brain 3 weeks after unilateral medial forebrain bundle lesion by 6-hydroxydopamine (6-OHDA). 5-HT 2A receptor distributions and alterations in the postmortem rat brain were detected by [3H]ketanserin-binding autoradiography. In the 6-OHDA-induced Parkinson’s rat model, nigrostriatal dopaminergic neuron loss significantly mediated the decreased [3H]ketanserin binding, predominantly in the agranular insular cortex (17.3%, P 5 0.03), cingulate cortex (18.2%, P < 0.001), prefrontal …
Structural Contributions Of Antipsychotic Drugs To Their Therapeutic Profiles And Metabolic Side Effects, Somayeh Jafari, Francesca Fernandez-Enright, Xu-Feng Huang
Structural Contributions Of Antipsychotic Drugs To Their Therapeutic Profiles And Metabolic Side Effects, Somayeh Jafari, Francesca Fernandez-Enright, Xu-Feng Huang
Xu-Feng Huang
Antipsychotic drugs have various neuropharmacological properties as a result of their structural diversity. Despite their therapeutic benefits, most of the prescribed atypical antipsychotics can induce severe side effects, including weight gain, type II diabetes mellitus, and cardiovascular diseases. Among the developed atypical antipsychotic agents, tetracyclic dibenzodiazepine and thienobenzodiazepine compounds, particularly clozapine and olanzapine, are associated with the greatest weight gain and metabolic disturbances. However, the unique chemical structure of these compounds causes the low risk of side effects reported for typical antipsychotics (e.g. extrapyramidal symptoms and tardive dyskinesia). This report reviews the recent discovery of the potential role of the …

Developmental Vitamin D Deficiency Alters Mk-801-Induced Behaviours In Adult Offspring, James Kesby, Jonathan O'Loan, Suzanne Alexander, Chao Deng, Xu-Feng Huang, John Mcgrath, Darryl Eyles, Thomas Burne
Developmental Vitamin D Deficiency Alters Mk-801-Induced Behaviours In Adult Offspring, James Kesby, Jonathan O'Loan, Suzanne Alexander, Chao Deng, Xu-Feng Huang, John Mcgrath, Darryl Eyles, Thomas Burne
Xu-Feng Huang
Rationale Developmental vitamin D (DVD) deficiency is a candidate risk factor for developing schizophrenia in humans. In rodents DVD deficiency induces subtle changes in the way the brain develops. This early developmental insult leads to select behavioural changes in the adult, such as an enhanced response to amphetamine-induced locomotion in female DVD-deficient rats but not in male DVDdeficient rats and an enhanced locomotor response to the Nmethyl- D-aspartate (NMDA) receptor antagonist, MK-801, in male DVD-deficient rats. However, the response to MK- 801-induced locomotion in female DVD-deficient rats is unknown. Therefore, the aim of the current study was to further examine …

The Effects Of Antipsychotic Drugs Administration On 5-Ht1a Receptor Expression In The Limbic System Of The Rat Brain, Mei Han, Xu-Feng Huang, Teresa Du Bois, Chao Deng
Xu-Feng Huang
Increasing evidence suggests that 5-HT1A receptors are involved in the pathophysiology and treatment of schizophrenia. This paper investigated 5-HT1A receptor mRNA expression and binding density in female rats treated with aripiprazole (2.25 mg/kg/day), olanzapine (1.5 mg/kg/day), haloperidol (0.3 mg/kg/day) or vehicle (control) orally three times/day for 1 or 12 weeks. Animals were sacrificed 48 h after the last administration. Aripiprazole significantly increased 5-HT1A receptor binding density by 33% in the CA1 region of the hippocampus and by 21% in the medial posterodorsal nuclei of posterior amygdala (MeP) compared to the control group after 1 week of treatment. Olanzapine significantly decreased …

Density Of Metabotropic Glutamate Receptors 2 And 3 (Mglur2/3) In The Dorsolateral Prefrontal Cortex Does Not Differ With Schizophrenia Diagnosis But Decreases With Age, Elisabeth Frank, Kelly Newell, Xu-Feng Huang
Density Of Metabotropic Glutamate Receptors 2 And 3 (Mglur2/3) In The Dorsolateral Prefrontal Cortex Does Not Differ With Schizophrenia Diagnosis But Decreases With Age, Elisabeth Frank, Kelly Newell, Xu-Feng Huang
Xu-Feng Huang
Metabotropic glutamate receptors 2 and 3 (mGluR2/3) have been shown as efficient targets for antipsychotic intervention. We therefore investigated the receptor density of mGluR2/3 in the dorsolateral prefrontal cortex (dlPFC; Brodman area 46) of schizophrenia/schizoaffective patients (n=37) and matched controls (n=37) using receptor autoradiography. No difference in mGluR2/3 density was identified in relation to schizophrenia diagnosis. Overall and in individual groups, a negative correlation of mGluR2/3 density and age at death has been found. These and previous results suggest that density of mGluR2/3 in the dlPFC is less likely to impact on the efficiency of the mGluR2/3 agonist in treating …
Antipsychotic Treatment And Neuregulin 1 -Erbb4 Signalling In Schizophrenia, Bo Pan, Xu-Feng Huang, Chao Deng
Antipsychotic Treatment And Neuregulin 1 -Erbb4 Signalling In Schizophrenia, Bo Pan, Xu-Feng Huang, Chao Deng
Xu-Feng Huang
Evidence from genetic, transgenic and post-mortem studies has strongly supported the critical role that neuregulin 1 (NRG1) and its ErbB4 receptor plays in the pathophysiology of schizophrenia. This article aims to review current evidence regarding the effects of antipsychotic treatment on NRG1–ErbB4 signalling. NRG1 and ErbB4 knockout mice display abnormal behaviours relevant to certain features of schizophrenia, which could be improved by antipsychotic (clozapine/haloperidol) treatment. In contrast to most NRG1/ErbB4 knockout mice with a decreased NRG1–ErbB4 signalling, the majority post-mortem studies showed an increased NRG1–ErbB4 signalling in schizophrenic patients. These differences could be due to degrees of alteration in risk …

Inter-Meal Interval Is Increased In Mice Fed A High Whey, As Opposed To Soy And Gluten, Protein Diets, Xu-Feng Huang, Timothy South, Yinghua Yu
Xu-Feng Huang
This study aimed to characterise meal patterns and satiety effects of diets that are high in protein but differ in protein source. Using a computerised automatic recording system, meal pattern behaviour was recorded continuously for 7 days in mice fed single (whey, soy or gluten) or different combined protein diets. Overall, average energy intake was significantly lower in mice fed a whey protein diet than those fed soy, gluten and lab chow diets. Among these four diets, the inter-meal interval of mice fed a whey protein diet was the longest and their meal number was the lowest. Combination of whey …

The present study investigated body weight gain, food intake, open-field activity and brain histamine H1 receptor mRNA and protein expression in rats treated with three types of antipsychotics. Rats were divided into eight groups and treated with aripiprazole (2.25mg/kg/day), olanzapine (1.5mg/kg/day), haloperidol (0.3mg/kg/day) or vehicle (as control) for 1 or 12 weeks. Administration of olanzapine for 1 week led to a threefold increase in body weight gain and a 35% increase in fat deposits compared to controls (p<0.05). In the 12-week olanzapine treatment group, accumulative food intake was significantly higher in the first 7 weeks of treatment compared to …

This study examined changes in neuropeptide Y (NPY) Y2 receptor binding in the brains of C57BL/6 mice in response to different levels of high-fat diets via three dietary intervention methods: high-fat diet, switching from high- to low-fat diet and finally, energy restricted high-fat diet. Forty-five C57Bl/6 male mice were fed a high-fat diet for 8 weeks and then classified as diet-induced obese (DIO) or diet-resistant (DR) mice according to the highest and lowest body weight gainers, respectively. The DIO and DR mice were then randomly divided into three groups each and either continued on their high-fat diet ad libitum (DIO-H …

No Changes In Densities Of Cannabinoid Receptors In The Superior Temporal Gyrus In Schizophrenia, Xu-Feng Huang, Chao Deng, Mei Han
Xu-Feng Huang
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 …

Statins are increasingly being used for the treatment of a variety of conditions beyond their original indication for cholesterol lowering. We previously reported that simvastatin affected the dopaminergic system in the rat brain. This study aims to investigate regional changes of muscarinic M1/4 receptors in the rat brain after 4-week administration of simvastatin (1 or 10 mg/kg/day). M1/4 receptor distribution and alterations in the post-mortem rat brain were detected by [3H]pirenzepine binding autoradiography. Simvastatin (1 mg/kg/day) increased [3H]pirenzepine binding, predominantly in the prefrontal cortex (171%, P<0.001), primary motor cortex (153%, P=0.001), cingulate cortex (109%, P<0.001), hippocampus (138%, P …

Aripiprazole Differentially Affects Mesolimbic And Nigrostriatal Dopaminergic Transmission: Implications For Long-Term Drug Efficacy And Low Extrapyramidal Side-Effects, Xu-Feng Huang, Chao Deng, Mei Han
Xu-Feng Huang
Aripiprazole has been used effectively to treat schizophrenia in the clinic ; however, its mechanisms ofaction are not clear. This study examined how short- and long-term aripiprazole treatment affects dopaminergic transmission in mesolimbic and nigrostriatal pathways. For comparison, the effects of haloperidol and olanzapine treatment were also examined. Aripiprazole significantly increased D2 receptor mRNA expression and decreased tyrosine hydroxylase (TH) mRNA expression in the ventral tegmental area (VTA) after 1- and 12-wk treatment, but had no effect in substantia nigra (SN) and nucleus accumbens (NAc). Aripiprazole also decreased dopamine transporter (DAT) binding density in NAc (for 1- and 12- wk …
