The mTORC1-dependent dendritic spines formation represents a key mechanism for fast and long-lasting antidepressant responses, but it remains to be determined whether this mechanism may account for the ability of guanosine in potentiating ketamine's actions. Here, we investigated the ability of ketamine plus guanosine to elicit fast and sustained antidepressant-like and pro-synaptogenic effects...
Ketamine has emerged as a prophylactic agent against depressive-like behavior induced by stress. However, the possible pro-resilience effects of ketamine against inflammatory stressors-induced depressive-like behavior and the signaling pathways associated with this response remain to be determined. Therefore, this study investigated the ability of prophylactic ketamine administration to produce...
Background Augmentation therapies may be effective strategies to potentiate the ketamine's actions with lower potential for knock-on effects. Thus, this study investigated the ability of combined administration of guanosine plus ketamine to elicit an antidepressant-like effect associated with mTOR pathway modulation. The ability of this combined administration to exert an antidepressant-like...
