Delta-sleep-inducing peptide (DSIP) is a neuropeptide that plays a role in several endocrine and physiological processes within the central nervous system. DSIP is of particular interest for its potential to:

• Reduce oxidative stress

• Normalize myocardial (heart muscle) contractility

• Serve as a therapeutic target in the treatment of major depressive disorder (MDD)

Ongoing research is evaluating DSIP’s broader implications in neuroprotection, stress modulation, and sleep regulation.
