DSIPA neuropeptide researched for its role in modulating sleep architecture, stress response, and endocrine function.
Delta Sleep-Inducing Peptide (DSIP) is a naturally occurring neuropeptide first identified in 1977 from cerebral venous blood of rabbits during induced sleep. This 9-amino acid peptide crosses the blood-brain barrier and has been shown to modulate sleep architecture, particularly promoting delta (deep) sleep stages. Research also explores its effects on cortisol and stress response regulation, pain modulation, and circadian rhythm normalization.
