DSIP References: Every Study Cited Here

The complete list of peer-reviewed sources behind the claims on this site, with DOIs and PubMed links.

About these references

Every quantitative claim across this DSIP digest is tied to a numbered source below, drawn from the peer-reviewed literature — PubMed-indexed journals including PNAS, the Journal of Neurochemistry, Peptides, and others. The list runs from the 1977 isolation paper to a 2024 study of an engineered DSIP fusion peptide. Where a study is paywalled, the DOI and PubMed link still let you locate the abstract and citation. The full reference details are listed in the sources section that follows.
