Abstract Major depressive disorder (MDD) is a prevalent psychiatric disorder, and is a leading cause of disability worldwide. Current treatments for MDD entail many side effects, and include a lag until the onset of therapeutic effects. The current hypotheses as for the etiology of MDD revolve around the monoamine hypothesis and the plasticity and neurodegeneration hypothesis. According to the...
Ketamine is a synthesized anesthetic drug that was used extensively as a surgical anesthetic in the 1960s. Currently, ketamine is being investigated extensively for its potential as a treatment for depression. However, the addictive nature of ketamine has become an issue that cannot be ignored at this stage. As of now, there is no clear understanding of the changes in striatal metabolites and...
Members of the neurotrophin family and in particular brain-derived neurotrophic factor (BDNF) regulate the response to rapid- and slow-acting chemical antidepressants and voluntary exercise. Recent work suggests that rapid-acting antidepressants that modulate N-methyl-D-aspartate receptor (NMDA-R) signaling (e.g., ketamine and GLYX-13) require expression of VGF (non-acronymic), the...
Driving under methylenedioxymethamphetamine (MDMA) influence increases the risk of being involved in a car accident, which in turn can lead to traumatic brain injury. The behavioral deficits after traumatic brain injury (TBI) are closely connected to dopamine pathway dysregulation. We have previously demonstrated in mice that low MDMA doses prior to mTBI can lead to better performances in...
Phencyclidine (PCP), used to mimic certain aspects of schizophrenia, induces sexually dimorphic, cognitive deficits in rats. In this study, the effects of sub-chronic PCP on expression of brain-derived neurotrophic factor (BDNF), a neurotrophic factor implicated in the pathogenesis of schizophrenia, have been evaluated in male and female rats. Male and female hooded-Lister rats received vehicle...
