it is released from hypothalamic nerve endings upon depolarization and inactivated by membrane-associated puromycin-sensitive aminopeptidase, consistent with a neuropeptide-like neuromodulator role ( Research demonstrates that DSIP inhibits hypothalamic somatostatin (SRIF) release in a dose-dependent manner (maximally at 10 M) via a dopaminergic mechanism (pimozide-reversible), suggesting a role in disinhibiting GH pulsatility during sleep ( Additional research characterizes multiple physiological effects including thermoregulation, blood pressure, and pain threshold modulation that appear circadian cycle-dependent ( For Research Use Only
