Comparative Study
Comparison of Therapeutic Effects of TREK1 Blockers and Fluoxetine on Chronic Unpredicted Mild Stress Sensitive Rats.
The animal model for depressive behavior due to chronic unpredicted mild stress (CUMS) is commonly used to evaluate antidepressant treatments. The CUMS model has faced some criticism because of the heterogeneity of behavioral effects. Spadin and SID1900 are TREK1 blockers with a quick antidepressant effect. ⋯ This study underlines the importance of model validation by determination of CUMS sensitivity. The TREK1 blockers were found to have an effect that was more rapid and more pronounced than that of fluoxetine. Therapeutic benefits after chronic administration were associated with a restoration of impaired neurogenesis.
