DSIP

Delta Sleep-Inducing Peptide (DSIP) is a naturally occurring nonapeptide. It has been studied for its potential involvement in sleep regulation, stress response, and neuroprotective activity. DSIP and DSIP-like peptides have been reported in various regions of the nervous system and other tissues, although their precise physiological role remains under investigation.

DSIP has also been studied for its potential involvement in stress response, thermoregulation, and neuroendocrine processes. The peptide is composed of nine amino acids arranged in the sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu.

Current research applications include studies on:

• Sleep physiology
• Circadian rhythm biology
• Molecular pathways involved in regulating sleep and wakefulness
