DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring neuropeptide studied in research models involving sleep regulation, circadian rhythms, stress-response pathways, and neuroendocrine signaling. Research has explored its potential involvement in sleep architecture, including slow-wave sleep, as well as stress adaptation, pain signaling, and hypothalamic-pituitary axis activity. DSIP continues to be investigated for its broader role in neurological function, physiological stress responses, and mechanisms associated with restorative sleep.
