Early Antipsychotic Treatment In Childhood/Adolescent Period Has Long-Term Effects On Depressive-Like, Anxiety-Like And Locomotor Behaviours In Adult Rats, Michael De Santis, Jiamei Lian, Xu-Feng Huang, Chao Deng
Early Antipsychotic Treatment In Childhood/Adolescent Period Has Long-Term Effects On Depressive-Like, Anxiety-Like And Locomotor Behaviours In Adult Rats, Michael De Santis, Jiamei Lian, Xu-Feng Huang, Chao Deng

Childhood/adolescent antipsychotic drug (APD) use is exponentially increasing worldwide, despite limited knowledge of the long-term effects of early APD treatment. Whilst investigations have found that early treatment has resulted in some alterations to dopamine and serotonin neurotransmission systems (essential to APD efficacy), there have only been limited studies into potential long-term behavioural changes. This study, using an animal model for childhood/adolescent APD treatment, investigated the long-term effects of aripiprazole, olanzapine and risperidone on adult behaviours of male and female rats. Open-field/holeboard, elevated plus maze (EPM), social interaction and forced swim (FS) tests were then conducted in adult rats. Our results …

Central Administrations Of Palmitic Acid And Arachidonic Acid Decrease Central Leptin Sensitivity In Mice, L Cheng, Xu-Feng Huang, Y Yu
Central Administrations Of Palmitic Acid And Arachidonic Acid Decrease Central Leptin Sensitivity In Mice, L Cheng, Xu-Feng Huang, Y Yu

Purpose: Leptin inhibits feeding and increases energy expenditure through the central nervous system. High-fat diet with saturated fatty acids (SFA) or n-6 polyunsaturated fatty acids (n-6 PUFA) has been reported to induce central leptin resistance and obesity. However, little is known if central administration of SFA or n-6 PUFA can reduce central leptin sensitivity. This study examined the central leptin sensitivity in response to intracerebroventricular (i.c.v.) injection of SFA, palmitic acid (PA) and n-6 PUFA, arachidonic acid (ARA) in mice. Methods: After overnight fasting, C57BL/6J male mice (n=24/group) were i.c.v. injected with either PA (50pmol/2ul), ARA (50pmol/2ul) or vehicle (saline, …

Neuropepetide Y (NPY) is best known for its powerful stimulation of food intake and its effects on reducing energy expenditure. However, the pathways involved and the regulatory mechanisms behind this are not well understood. Here we demonstrate that NPY derived from the arcuate nucleus (Arc) is critical for the control of sympathetic outflow and brown adipose tissue (BAT) function. Mechanistically, a key change induced by Arc NPY signaling is a marked Y1 receptor-mediated reduction in tyrosine hydroxylase (TH) expression in the hypothalamic paraventricular nucleus (PVN), which is also associated with a reduction in TH expression in the locus coeruleus (LC) …

A Neuregulin 1 Transmembrane Domain Mutation Causes Imbalanced Glutamatergic And Dopaminergic Receptor Expression In Mice, K A. Newell, T Karl, Xu-Feng Huang

The neuregulin 1 gene has repeatedly been identified as a susceptibility gene for schizophrenia, thus mice with genetic mutations in this gene offer a valuable tool for studying the role of neuregulin 1 in schizophrenia-related neurotransmission. In this study, slide-based receptor autoradiography was used to quantify glutamatergic N-methyl-d-aspartate (NMDA), dopaminergic D2, cannabinoid CB1 and acetylcholine M1/4 receptor levels in the brains of male heterozygous transmembrane domain neuregulin 1 mutant (Nrg1+/−) mice at two ages. Mutant mice expressed small but significant increases in NMDA receptor levels in the cingulate cortex (7%, p = 0.044), sensory cortex (8%, p = 0.024), and …

Purpose: Metabotropic glutamate receptors (mGluRs) are proposed novel therapeutic targets for a variety of brain disorders such as schizophrenia (SZ), bipolar disorder (BP) and major depression (MD). Despite their potential, the involvement of these receptors in these pathological processes is uncertain. This information is crucial to understand the efficiency of drugs that target these receptors. Methods: Using post-mortem human brains, mGluR2/3 and mGluR5 binding densities were measured in the anterior cingulate cortex of SZ, BP, MD and matched controls (CT) (n=15/group) by receptor autoradiography. Results: Whilst preliminary analyses indicated no diagnostic effect in mGluR2/3 or mGluR5 binding densities, mGluR2/3 binding …
