DSIP
Sleep-research peptide
DSIP is a short peptide first found in the 1970s in the blood of sleeping rabbits. It was named after those early experiments, where it showed up alongside the slow brain waves seen during deep sleep in animals.
Also known as Delta Sleep-Inducing Peptide
How it is studied
How it works in the body is not well understood. In the research literature it is linked to sleep- and stress-related brain signaling, but scientists have not pinned down a specific place it acts on.
Research context
A reference compound in sleep and hormone research, studied in animal and laboratory models of the sleep-wake system.
Good to know
Only limited and inconsistent early research exists, and how it works is still unclear. Research use only.
Research area
Cognition, mood & sleep research. This group covers molecules that scientists study in the brain, in the body's stress-response system, and in the sleep-wake cycle. Most are short chains of amino acids (the tiny building blocks of proteins), and a couple are signaling substances the body makes on its own. All are described here for laboratory research only.
