Thymosin Alpha-1 (Tα1) — Approved Immune Modulator | Research Grade
Thymosin Alpha-1 is the N-terminally acetylated 28-amino-acid peptide derived from prothymosin alpha — one of the thymic hormones responsible for T-cell maturation and immune competence. Available commercially as Zadaxin® with regulatory approval in 30+ countries (Italy, China, and others) for hepatitis B, hepatitis C, non-small cell lung cancer, and malaria immunotherapy, Thymosin Alpha-1 has one of the richest clinical evidence bases of any research peptide.

Key Research Areas
🛡️ Innate & Adaptive Immune Activation
Tα1 activates toll-like receptor (TLR) 9 signalling on dendritic cells and plasmacytoid DCs, driving type I interferon production and Th1 immune polarization. Research demonstrates enhanced NK cell function, CD8+ T-cell activation, and dendritic cell maturation — boosting both innate and adaptive immunity.
🦠 Antiviral Research (Hepatitis B/C)
Approved clinical evidence demonstrates Tα1’s ability to reduce viral load, improve seroconversion rates, and enhance interferon efficacy in hepatitis B and C research models. These Phase 3 trial data provide the highest quality evidence available for any thymic peptide.
🏥 Sepsis & Critical Illness Research
Recent research has explored Tα1 in sepsis models — where immune exhaustion and immunoparalysis dramatically worsen outcomes. Studies show Tα1 reverses immune exhaustion, improves 28-day survival rates, and restores T-cell function in sepsis research models.
🧬 Cancer Immunotherapy Research
Tα1 enhances the efficacy of checkpoint inhibitors, vaccines, and conventional cancer therapies via immune system upregulation. Research spans multiple cancer models including lung, colon, and hepatocellular carcinoma.
