What is DSIP and How Does It Work?
Delta sleep-inducing peptide (DSIP) is a naturally occurring nonapeptide. It was first isolated from rabbit brain in 1977. The peptide is normally made in the hypothalamus and acts on multiple brain sites, including parts of the brainstem. As the name suggests, DSIP promotes sleep. Specifically, it increases the delta rhythm on the EEG, a marker of deep sleep.
DSIP appears in the blood in very small amounts. Brain and plasma levels change throughout the day. Levels are lower in the morning and higher in the afternoon. Raised endogenous DSIP has been linked to changes in slow-wave and REM sleep and to body temperature changes.
Plasma concentrations of DSIP rise with the start of sleep. For example, patients with Cushing’s syndrome have less slow-wave sleep. Still, their daily sleep rhythm looks similar to normal patients.
Compared with many peptides, DSIP can cross the blood–brain barrier. It is also readily absorbed from the gut without being broken down by enzymes. DSIP shows up in human milk at measurable levels (10–30 ng mL–1). Many breastfeeding mothers notice that a feed can make the baby sleepy.
