Endoplasmic reticulum (ER) stress and misfolded proteins accumulation are recognized as central factors in the development of psychiatric disorders. This study evaluated the potential therapeutic effect of fluvoxamine, a potent sigma-1 receptor agonist in alleviating protein misfolding and the subsequent ER stress in ketamine-induced model of schizophrenia. NE100 hydrochloride, a sigma-1...
Imbalances in redox and neuroinflammation are believed to play a role in the complex causes of schizophrenia, a widespread mental disorder characterized by abnormal behaviour. In this regard, we investigated the effects of geraniol, a natural compound with various medicinal uses, on ketamine-induced schizophrenia-like behaviour, oxidative stress and neuroinflammation in mice. We conducted three...
Marijuana (MJ) use is associated with cognitive deficits. Both mitochondrial (mt) dysfunction and gut dysbiosis also affect cognition. We examined whether cognition is related to peripheral blood mononuclear cells' (PBMCs) mt function and fecal microbiota in chronic MJ users. Nineteen chronic MJ users and 20 non-users were evaluated using the Cognition Battery in NIH Toolbox, their mt function...
3,4-Methylenedioxymethamphetamine (MDMA; Ecstasy) is a popular drug of abuse with well-documented acute effects on serotonergic, dopaminergic, and cholinergic transmitter systems, as well as evidence of long-term disruption of serotoninergic systems in the rat brain. Recently, it was demonstrated that MDMA evokes a delayed and sustained increase in glutamate release in the hippocampus. The...
Methamphetamine (METH) and 3,4-methylenedioxymethamphetamine (MDMA, ecstasy) are amphetamine derivatives with high abuse liability. These amphetamine-related drugs of abuse mediate their effects through the acute activation of both dopaminergic and serotonergic neurons. Long-term abuse of these amphetamine derivatives, however, results in damage to both dopaminergic and serotonergic terminals...
