About Thymosin Alpha-1
About Thymosin Alpha-1
Thymosin Alpha-1 (CAS: 62304-98-7) is a naturally occurring 28-amino acid peptide first isolated from thymosin fraction 5, a preparation derived from bovine thymus tissue. It is an N-terminally acetylated peptide that plays a central role in immune system maturation and regulation. Thymosin Alpha-1 has been one of the most extensively studied thymic peptides, with research spanning several decades across immunology and infectious-disease research fields.
Mechanism of Action
Thymosin Alpha-1 acts as a biological response modifier, enhancing immune function through multiple pathways. It promotes the differentiation and maturation of dendritic cells, enhancing their antigen-presenting capacity. The peptide stimulates T-cell maturation from progenitor cells via upregulation of T-cell surface markers. It modulates cytokine production, shifting the balance toward Th1 responses, and activates natural killer (NK) cell cytotoxicity. Additionally, Thymosin Alpha-1 signals through Toll-like receptors (TLR-2 and TLR-9) on myeloid and plasmacytoid dendritic cells.
