Delta Sleep-Inducing Peptide (DSIP)

What Is DSIP?
Delta Sleep-Inducing Peptide, also known as DSIP or emideltide, is a nine-amino-acid peptide first identified during experiments involving sleep-associated biological material. Research conducted mainly during the late twentieth century examined its relationship to sleep architecture, stress responses, pain signaling, and neuroendocrine regulation.
Human studies were generally small and produced inconsistent findings. Its precise endogenous origin, receptor interactions, and physiological role remain incompletely understood.
