Thymosin Alpha-1

Thymosin Alpha-1 (Tα1) is a peptide fragment derived from prothymosin alpha, a protein naturally produced by the thymus gland. Consisting of 28 amino acids, Tα1 is widely recognized in scientific literature as a potent biological response modifier. It plays a critical role in the modulation of the immune system, particularly in the maturation and differentiation…

Research & Mechanisms

1. T-Cell Maturation and Immune Regulation The primary function of Tα1 in research models is its ability to stimulate the development of precursor T-cells into active T-cells (CD4+ and CD8+). Studies suggest it helps restore immune homeostasis by balancing the ratio of helper T-cells to cytotoxic T-cells, which is vital for effective immune responses in immunocompromised models.

2. Viral Replication Inhibition Researchers investigate Tα1 for its direct and indirect antiviral properties. It is observed to modulate the expression of Toll-like receptors (TLRs) and stimulate the production of essential cytokines like Interferon-alpha (IFN-α) and Interleukin-2 (IL-2), creating an environment unfavorable for viral replication.

3. Oxidative Stress and Inflammation Beyond direct immunity, Tα1 is studied for its antioxidant capacity. Preclinical data indicates it may increase the activity of antioxidant enzymes (such as superoxide dismutase) and reduce chronic inflammation markers, suggesting a role in cellular protection and longevity research.
