The cited record

These are the primary sources behind the Thymosin Alpha-1 appraisal on this site. Each carries a DOI or PubMed identifier so the claim can be verified at the source. The list spans the foundational characterization, the mechanism work, the sepsis and COVID-19 trials, the hepatitis B meta-analyses, and the autoimmune-tolerance studies that anchor this site's lens. Where the literature is heterogeneous or a result was null, the body pages say so explicitly rather than smoothing it over.
