Research Overview
DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring nonapeptide first isolated from rabbit brain during slow-wave sleep. It is used in laboratory studies of sleep architecture, stress-response biology, and neuroendocrine modulation.
Mechanism of Action
DSIP's exact mechanism remains an active area of research. In-vitro models suggest interactions with GABAergic, opioidergic, and HPA-axis signaling.
Research Applications
- Sleep architecture research
- HPA-axis modulation studies
- Neuropeptide screening
