1. What is Thymosin Alpha-1?
Thymosin Alpha-1 (Tα1) is a naturally occurring 28-amino acid peptide fragment originally identified in the thymus. It has been studied extensively for its role in immune regulation, cellular signaling, and antiviral research contexts. As a thymic peptide, it is particularly noted for influencing T-cell activity, cytokine modulation, and immune resilience, which has made it a focus of both basic science and translational research.
