Research Data

What Is DSIP?

DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring nonapeptide first isolated from the cerebral venous blood of sleeping rabbits. It has been studied as a neuromodulator affecting sleep-wake architecture, HPA axis regulation, and stress-related peptide systems. Research investigates its role in delta-wave (slow-wave) sleep promotion and potential stress-axis modulation properties.

Research Context

Delta-wave (slow-wave) sleep architecture modulation studies
HPA axis regulation and cortisol stress-response pathway research
Neuromodulatory peptide interactions in thalamo-cortical systems
Comparison with benzodiazepines in GABA-independent sleep models
