Outcomes summary

Preclinical study describing PE 22-28 as a shortened spadin-derived peptide that inhibits the TREK-1 channel in vitro and shows antidepressant-like effects across multiple rodent behavioral models, alongside reported effects on neurogenesis/synaptogenesis markers.

Limitations

Preclinical models; behavioral endpoints do not guarantee clinical antidepressant efficacy; results depend on peptide identity, formulation, and experimental conditions.
