Molecular signature underlying (R)-ketamine rapid antidepressant response on anhedonic-like behavior induced by sustained exposure to stress.

Pharmacology, Biochemistry, and Behavior December 1, 2024 Ellen Scotton, Paola Rampelotto Ziani, Renata Luiza Boff Wilges et al. 1 citation

Anhedonia induced by sustained stress exposure is a hallmark symptom of major depressive disorder (MDD) and in rodents, it can be accessed through the sucrose preference test (SPT). (R)-ketamine is a fast-acting antidepressant with less detrimental side effects and abuse liability compared to racemic ketamine. The present study combined high-throughput proteomics and network analysis to...

Differentially regulated targets in the fast-acting antidepressant effect of (R)-ketamine: A systems biology approach.

Pharmacology, Biochemistry, and Behavior February 2023 Ellen Scotton, Pedro Lenz Casa, Fernanda Pessi De Abreu et al.

Approximately two-thirds of patients with major depressive disorder (MDD) fail to respond to conventional antidepressants, suggesting that additional mechanisms are involved in the MDD pathophysiology. In this scenario, the glutamatergic system represents a promising therapeutic target for treatment-resistant depression. To our knowledge, this is the first study using semantic approach with...

Is (R)-ketamine a Potential Therapeutic Agent for Treatment-Resistant Depression with Less Detrimental Side Effects? A Review of Molecular Mechanisms Underlying Ketamine and its Enantiomers.

Biochemical Pharmacology February 1, 2022 Ellen Scotton, Bárbara Antqueviezc, Mailton Vasconcelos et al. 35 citations

Approximately one-third of individuals with major depressive disorder are resistant to conventional antidepressants (i.e., monoamine-based therapies), and, even among respondents, a proper therapeutic effect may require weeks of treatment. Ketamine, a racemic mixture of the two enantiomers, (R)-ketamine and (S)-ketamine, is an N-methyl-d-aspartate receptor (NMDAR) antagonist and has been shown...
