Current antidepressants are clinically effective only after several weeks of administration. Here, we show that serotonin(4) (5-HT(4)) agonists reduce immobility in the forced swimming test, displaying an antidepressant potential. Moreover, a 3 day regimen with such compounds modifies rat brain parameters considered to be key markers of antidepressant(More)
From clinical studies it is known that recurrent depressive episodes associate with a reduced hippocampal volume. Conversely, preclinical studies have shown that chronic antidepressant treatment increases hippocampal neurogenesis. Consequently, it has been suggested that a deficit in hippocampal neurogenesis is implicated in the pathophysiology of(More)
The aim of the present study was to identify potential biomarkers for depression in the search for novel disease targets and treatment regimens. Furthermore, the study includes a search for biomarkers involved in treatment resistance and stress resilience in order to investigate mechanisms underlying antidepressant drug refraction and stress-coping(More)
Several findings suggest a functional and anatomical differentiation along the dorso-ventral axis of the hippocampus. Lesion studies in rats have indicated that the dorsal hippocampus preferentially plays a role in spatial learning and memory, while the ventral hippocampus is involved in anxiety-related behaviors. Based on such findings our aim was to(More)
Extensive preclinical research has focused at unravelling the underlying molecular mechanisms leading to depression and recovery. In this study, we investigated the quantitative changes in protein abundance in the ventral hippocampal granular cell layer. We compared different phenotypes from the chronic mild stress (CMS) model of depression using chronic(More)
The development of depression as well as recovery from depression is most likely accompanied by a change in protein expression profiles. The purpose of the present study was to quantitatively investigate global protein expression differences independent of any hypothesis describing depression etiology and recovery. Thus two-dimensional differential in-gel(More)
Stress and depression cause structural changes in the hippocampal formation. Some of these can be reversed by chronic antidepressant treatment. In the present study, we examined the changes in the total number of granule cells and the volume of the granule cell layer after exposing rats to chronic mild stress and chronic escitalopram treatment. Furthermore,(More)
