28-amino acid N-acetylated thymic peptide. TLR2/9 agonist and innate/adaptive immune modulator for immune pathway and antiviral signaling research.
Thymosin alpha-1 (Ta1) is a naturally occurring 28-amino acid N-acetylated peptide originally isolated from thymosin fraction 5. It is one of the most extensively characterized immunomodulatory peptides, activating dendritic cells, T-cells, and NK cells through Toll-like receptor-2/9 (TLR2/9) agonism. Ta1 enhances IL-12, IFN-alpha/beta, and MHC II expression while modulating regulatory T-cell responses.
