Neuroscience
Enkephalin and GABA-related anxiety signalling
Neuropeptide and inhibitory-neurotransmitter systems contribute to anxiety, stress adaptation and emotional regulation.
Biological pathway
Selank has been reported to affect enkephalin metabolism, GABA-related signalling and expression of genes involved in neurotransmission.
Evidence summary
Small clinical comparisons and preclinical studies support anxiolytic activity, though the evidence base is geographically concentrated.
Limitations
Mechanisms remain incompletely established and clinical replication outside the original research setting is limited.
