DSIP: Research Overview
Delta Sleep-Inducing Peptide (DSIP) is a naturally occurring neuropeptide first isolated from rabbit cerebral venous blood in 1977. It was named for its ability to induce delta wave sleep (slow-wave sleep) in research models and has since been studied for various neuroendocrine effects.

Frequently Asked Questions
What does DSIP stand for?
DSIP stands for Delta Sleep-Inducing Peptide, named for its ability to promote delta wave (slow-wave) sleep in the original research models where it was studied.
Is DSIP found naturally in the body?
Yes, DSIP is a naturally occurring neuropeptide found in brain tissue, blood plasma, and cerebrospinal fluid. It was first isolated from rabbit brain venous blood in 1977.
What research areas use DSIP?
DSIP is used in sleep architecture research, stress response studies, neuroendocrine investigations (particularly HPA axis), and pain modulation research. It's studied for its effects on delta wave sleep and cortisol regulation.
