DSIP (Delta Sleep-Inducing Peptide) Endogenous Neuropeptide | Research Use Only
Delta Sleep-Inducing Peptide (DSIP) is a naturally occurring nonapeptide first isolated from the cerebral venous blood of sleeping rabbits by Monnier et al. in 1977. Since its discovery, DSIP has been the subject of extensive preclinical investigation across neuroendocrine and neuropharmacological research disciplines.
In laboratory and animal model studies, DSIP has been investigated for its interactions with the hypothalamic-pituitary axis, stress hormone modulation, and neuroendocrine signaling pathways. Research has explored its behavior in circadian rhythm models, opioid receptor studies, and pain response investigations. Additionally, DSIP has been studied in models examining oxidative stress, free radical scavenging activity, and mitochondrial function. It is frequently utilized as a research tool in studies examining neuropeptide signaling mechanisms and central nervous system regulatory pathways.
