When TREK-1 channels are blocked in a research setting, downstream effects observed in pre-clinical models include: Serotonin pathway modulation TREK-1 inhibition influences serotonergic transmission, producing effects in mood-related behavioural models Hippocampal neurogenesis stimulation research indicates PE22-28 promotes the growth of new neurons in the hippocampus, with studies reporting a doubling of neurogenesis biomarkers in treated models Synaptogenesis PE22-28 has been associated with increased synaptic connection formation in hippocampal tissue in pre-clinical models Rapid onset of effect compared to classical antidepressant drugs such as fluoxetine, which require 34 weeks for effects to manifest, Spadin-class peptides act rapidly within only 4 days of treatment a property PE22-28 retains and improves upon Selective TREK-1 specificity PE22-28 does not meaningfully interact with related K2P channels including TREK-2, TRAAK, TRESK, or TASK-1, nor does it affect hERG channel activity, indicating high selectivity What Does PE22-28 Do in Research
