Graf M: 5-HT2c receptor activation induces grooming behaviour in rats: possible correlations with obsessive-compulsive disorder. Neuropsychopharmacol Hung. 2006 Mar;8(1):23-8.
Excessive self-grooming in animal models of obsessive-compulsive disorder (OCD) is regarded as an equivalent of compulsive behaviour in OCD patients. Previous studies have suggested a key modulatory role of certain serotonin2 receptor subtypes both in grooming behaviour and OCD. Certain 5-HT2 receptor agonists were reported to exacerbate symptoms in OCD patients. Here we report that activation of the serotonin2c (5-HT2c) receptor induces self-grooming in rats, which result supports the hypothesis that selective stimulation of central 5-HT2c receptors exacerbates symptoms also in OCD. The present findings may help to understand serotonergic mechanisms underlying psychiatric disorders of the obsessive-compulsive spectrum and may progress the development of novel anxiolytic and anti-OCD medications. |
