Selank is a synthetic peptide derived from tuftsin that has been studied for its potential effects on anxiety, mood, cognition, and immune regulation. Research suggests it may influence neurotransmitters such as serotonin and affect brain-derived neurotrophic factor (BDNF), which is involved in brain function and neural health.
Selank has been studied for its potential anti-anxiety and neuroprotective effects. Its activity has been compared with traditional anti-anxiety medicines that influence GABAA receptors. Research suggests that Selank may help reduce anxiety and stress while supporting mood, memory, and learning. Unlike benzodiazepines, it has not been strongly associated with addiction, withdrawal, or memory loss in experimental studies.
Rat studies found that Selank affected several genes involved in GABA signaling. These changes may influence how nerve cells respond to GABA and could help explain its calming effects. Research also suggests that Selank may work alongside medicines that act on GABA receptors, although more studies are needed.
Selank and benzodiazepines have shown similar effects on anxiety in animal studies. Selank may also help manage stress-related symptoms, but its exact benefits and clinical applications remain under investigation.
Another possible mechanism involves enkephalinase, an enzyme that breaks down enkephalins, which are natural peptides involved in pain control and stress regulation. By slowing enkephalin breakdown, Selank may help preserve these natural compounds and support the body's response to anxiety.
Research suggests that Selank may influence immune and inflammatory pathways. In some studies involving depression, it reduced activity of the gene responsible for producing the inflammatory protein IL-6. This effect was not observed in healthy participants, suggesting that Selank may act differently depending on the body's condition.
Compared with some standard anxiety treatments, Selank has been studied for its possible effects on both anxiety and asthenic symptoms, such as fatigue and pain. These effects may involve changes in IL-6 activity and the breakdown of enkephalins.
Animal studies have also shown that Selank can affect genes involved in inflammation, including genes related to chemokines, cytokines, immune receptors, and immune-system development. It may also temporarily influence immune-related gene activity in the spleen.
Anxiety can interfere with memory and learning, and Selank has been studied for its possible ability to reduce these effects. In rat studies, Selank improved memory stability and helped support the storage of learned information, regardless of the animals' anxiety levels.
Research suggests that Selank may influence gene activity in the hippocampus, a brain region involved in memory and learning. Changes in several genes may affect cell membranes, ion movement, and communication between neurons.
Some animal studies have also explored Selank's ability to support memory and learning after brain damage. These effects may involve changes in brain chemical systems, although further research is needed to understand the mechanism.
Selank may help reduce the breakdown of enkephalins, natural peptides that bind to opioid receptors and help control pain. Enkephalins are also involved in stress responses, memory, learning, and attention. By slowing their breakdown, Selank may support the body's natural pain-relief and stress-regulation processes.
