DSIP has been described as a sleep-promoting substance. There is a modulating effect on sleep and wake functions with a greater activity in circumstances where sleep is disturbed. There are minimal effects in healthy subjects who are not suffering from sleep disturbance.

Delta sleep-inducing peptide, abbreviated DSIP, is a neuropeptide that when infused into the mesodiencephalic ventricle of recipient rabbits induces spindle and delta EEG activity and reduced motor activities. Its aminoacid sequence is TRP-ALA-GLY-GLY-ASP-ALA-SER-GLY-GLU However, the gene is unknown[citation needed], raising serious questions regarding the actual existence of this peptide in nature.

3. Core Research Mechanisms of DSIP
Numerous in vitro and preclinical laboratory studies have confirmed that DSIP exerts its biological effects through multiple key pathways, making it a widely used research tool in neurobiology and sleep science. Its core research mechanisms are as follows:

- Sleep Structure Regulation: DSIP is widely known for its ability to enhance slow-wave sleep (SWS, also known as delta sleep), which is crucial for physical recovery and cognitive function consolidation. Laboratory data show that DSIP can prolong deep sleep time, optimize the balance between rapid eye movement (REM) sleep and non-rapid eye movement (NREM) sleep, and improve sleep quality without inducing sedation or dependence, distinguishing it from traditional hypnotics. This mechanism makes it an ideal tool for studying sleep regulation and developing non-addictive sleep regulators.

- Neuroprotective and Antioxidant Activity: DSIP has been shown to possess significant antioxidant properties, capable of scavenging free radicals and reducing neuronal damage caused by oxidative stress. It can protect nerve cells from ischemic and hypoxic damage, regulate neurotransmitter release, and support synaptic plasticity, showing potential protective effects in preclinical models of neurodegenerative diseases such as Alzheimer's and Parkinson's. Furthermore, it has anticonvulsant effects, raising the threshold for NMDA and bitter substances-induced seizures, which is of significant value for epilepsy research.

- Stress response and hypothalamic-pituitary-adrenal (HPA) axis regulation: DSIP can regulate the activity of the hypothalamic-pituitary-adrenal (HPA) axis, reduce cortisol levels, and alleviate stress responses in preclinical animal models. It also possesses anti-anxiety properties, interacting with the GABAergic and opioid systems, making it an important research tool for exploring the neurobiological mechanisms of anxiety, post-traumatic stress disorder (PTSD), and stress. In addition, studies have shown that it can alleviate withdrawal symptoms of alcohol and opioids, providing support for research into addiction mechanisms.
