The superior temporal gyrus (STG) is strongly implicated in the pathophysiology of schizophrenia,particularly with regards to auditory hallucinations. In this study, using in situ quantitative autoradiography in postmortem tissue, we investigated the binding of the [3H]ketanserin to 5-HT2A receptors and [3H] mesulergine to 5-HT2C receptors in the left STG of 8 male schizophrenic patients compared to 8 control subjects. A strong [3H]ketanserin binding was observed in the STG, however there was a very weak [3H] mesulergine binding in the STG. A significant decrease in binding of [3H]ketanserin was clearly observed in schizophrenia patients in comparison with control subjects. There were …


No Changes In Densities Of Cannabinoid Receptors In The Superior Temporal Gyrus In Schizophrenia, Xu-Feng Huang, Chao Deng, Mei Han Sep 2012

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

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 …

Temporal And Site-Specific Brain Alterations In Cb1 Receptor Binding In High Fat Diet-Induced Obesity In C57bl/6 Mice, Xu-Feng Huang, Timothy South Sep 2012

Temporal And Site-Specific Brain Alterations In Cb1 Receptor Binding In High Fat Diet-Induced Obesity In C57bl/6 Mice, Xu-Feng Huang, Timothy South

The cannabinoid CB1 receptor has been implicated in the regulation of appetite and the consumption of palatable foods. This experiment aimed to explore the involvement of the CB1 receptor in the early and late stages of high fat diet-induced obesity in C57BL/6 mice. The C57Bl/6 mice were placed on a high fat (HF) or low fat/high carbohydrate (LF) diet for 3 or 20 weeks. Quantitative autoradiography revealed that binding of [3H] CP-55,940 (CB1 receptor ligand) was elevated following 3 weeks of HF feeding in areas including the medial/ventral anterior olfactory nucleus (22.1%), agranular insular cortex (24.0%) and the hypothalamus (31.5%) …
