There is substantial evidence implicating altered serotonergic function in depression. While some subtypes of 5-HT receptors have been extensively studied in relation to depression, others have yet to be investigated. In this study, the authors have examined 5-HT1D and 5-HT1E/1F binding sites in brain tissue obtained post-mortem from suicides with a retrospective diagnosis of depression and matched controls. Higher 5-HT1D binding was found in globus pallidus of suicides free from antidepressant drug treatment, and was largely restricted to those who died by violent means. There were no differences in 5-HT1D binding in putamen, parietal or frontal cortex and no differences in 5-HT1E/1F binding in any of the regions studied.
