Depression is a highly prevalent and incident mental illness. Current pharmacological therapies fail in approximately 30-40% of patients, highlighting the urgent need for novel agents with pleiotropic effects. This preclinical study aimed to identify new antidepressants and cognitive modulators among five phytocannabinoids: cannabichromene, cannabidiol, cannabidivarin, cannabigerol and...
3,4-Methylenedioxymethamphetamine (MDMA) is still one of the most consumed drugs by adolescents. Its abuse is related with cognitive impairment, which seems due to maladaptive plasticity and neural stress. In turn, new hypotheses suggest that Alzheimer's disease (AD) may be promoted by neural stressors. To test if there is an increase in vulnerability to AD after chronic MDMA consumption, we...
The neurotoxic action of the abuse drugs methamphetamine (METH) and 3,4-methylenedioxymethamphetamine (MDMA) on cerebellar granule neurones (CGNs) culture was examined. Treatment for 48 h with METH or MDMA (1-5 mM) induced a higher decrease in viability than 24 h treatment. z.VAD.fmk (100 microM) but not MK-801 nor NBQX recovered control viability values. In both cases, cell death was...
