Delta sleep-inducing peptide, abbreviated DSIP, is a neuropeptide that when infused into the mesodiencephalic ventricle of recipient rabbits induces spindle and delta EEG activity and reduced motor activities
A first study of DSIP application to humans was carried out in six normal volunteers (four males and two females) under extensive psychophysiologic observations and measurements in a double-blind cross-over design. DSIP was applied as slow intravenous infusions at a dosage of 25 nmol/kg in the morning. The subjects immediately reported a feeling of sleep pressure, and sleep increased by 59% (median of total sleep time) within a 130-min interval after the treatment as compared with placebo.
Delayed effects on subsequent night sleep were shorter sleep onset, reduced percentage of stage 1, and better sleep efficiency. Nevertheless, sophisticated behavioral and EEG analyses revealed no sedation in the classic pharmacologic way. The results suggest that DSIP in humans is also efficacious by sustaining natural sleep functions. The compound was well-tolerated and no psychologic, physiologic, or biochemical side effects were observed.
DSIP (Delta Sleep-inducing Peptide) is a neuropeptide found in the hypothalamus, pituitary, and adrenal glands. Its isolation has allowed for extensive research which has found several possible primary and peripheral roles of this peptide. First, DSIP has been shown to induce sleep. Second, it may have benefits as an analgesic in treatment of chronic pain, sometimes as an adjunct treatment. Third, DSIP has been shown to block ACTH release and decrease levels of ACTH, stimulate LH release, and act as an inhibitor of the secretion of somatostatin. The source of production of DSIP is yet unknown; It may be produced in the central nervous system or in a peripheral organ. It is thought to pass
Through the blood-brain barrier (BBB) more easily than most known neuropeptides. As mentioned, DSIP has shown positive results in inducing slow-wave EEG (sleep). It has been shown to help treat narcolepsy and restore disturbed sleep patterns to normal sleep rhythms.
Many roles for DSIP have been suggested following research carried out using peptide analogues with a greater molecular stabilityand through measuring DSIP-like immunological (DSIP-LI) response by injecting DSIPantiserum and antibodies.
Roles in endocrine regulation
Decreases basal corticotropin level and blocks its release.
Stimulates release of luteinizing hormone (LH).
Stimulates release of somatoliberin and somatotrophin secretion and inhibits somatostatin secretion.
Delta sleep-inducing peptide, abbreviated DSIP, is a neuropeptide that when infused into the mesodiencephalic ventricle of recipient rabbits induces spindle and delta EEG activity and reduced motor activities.
Delta sleep-inducing peptide was first discovered in 1974 by the Swiss Schoenenberger-Monnier group who isolated it from the cerebral venous blood of rabbits in an induced state of sleep. It was primarily believed to be involved in sleep regulation due to its apparent ability to induce slow-wave sleep in rabbits, but studies on the subject have been contradictory.
