Delta Sleep-Inducing Peptide (DSIP) is a naturally occurring peptide sequence originally isolated in association with sleep-related neurophysiological activity. It has been investigated in experimental models examining neuroendocrine regulation, stress-response pathways, circadian signalling, and peptide-mediated neuronal activity. Its precise biological mechanisms remain an area of ongoing research.
