The Effects Of Antipsychotics On The Density Of Cannabinoid Receptors In The Dorsal Vagal Complex Of Rats: Implications For Olanzapine-Induced Weight Gain, Katrina Weston-Green, Xu-Feng Huang, Mei Han, Chao Deng

Some atypical antipsychotics clinically used to treat schizophrenia induce weight gain by unknown mechanisms. The dorsal vagal complex (DVC) of the brainstem and the endogenous cannabinoid system are implicated in the regulation of appetite signalling and food intake. We investigated whether antipsychotic drugs alter cannabinoid receptor-binding density in the DVC. Female Sprague–Dawley rats were treated with olanzapine, haloperidol, aripiprazole or vehicle for 1 wk (short-term) or 12 wk (chronic). Quantitative autoradiographic methods were employed to investigate the binding density of cannabinoid receptors in the DVC using a highly sensitive Beta Imager. Short-term olanzapine induced a significant 39% decrease in cannabinoid …

This study examined regional changes of peptide YY (PYY) binding densities in the rat brain after chronic administration of olanzapine (1.2 mg/kg/day and haloperidol (2.0 mg/kg/day)for 36 days. PYY binding densities and distributions were detected by [125I] binding autoradiography after ratswere sacrificed either 2 h or 48 h after the last drug administration to examine both immediate and delayed effects following the drugwithdrawal. Following 2 h of drug administration, it showed that olanzapine administration significantly decreased PYY binding densities, predominantly in the posterodorsal part of medial amygdaloid nucleus (52 percent, pb0.05), dorsal part of medial geniculate nucleus (56 percent, pb0.05), …

Background/Aim: Second generation antipsychotics (SGAs) are used to treat schizophrenia but can cause serious metabolic side-effects, such as obesity and diabetes. This study examined the effects of low to high doses of olanzapine on appetite/ metabolic regulatory signals in the hypothalamus and brainstem to elucidate the mechanisms underlying olanzapineinduced obesity. Methodology/Results: Levels of pro-opiomelanocortin (POMC), neuropeptide Y (NPY) and glutamic acid decarboxylase (GAD65, enzyme for GABA synthesis) mRNA expression, and cannabinoid CB1 receptor (CB1R) binding density (using [3H]SR- 141716A) were examined in the arcuate nucleus (Arc) and dorsal vagal complex (DVC) of female Sprague Dawley rats following 0.25, 0.5, 1.0 …
