Thymosin Alpha 1

Thymosin Alpha 1 (Tα1) is a 28-amino-acid polypeptide secreted by the thymus gland with potent immunomodulatory activity. It enhances the immune response by boosting T-cell function, promoting natural killer (NK) cell activity, and regulating cytokine production. Tα1 has been approved in multiple countries for the treatment of chronic hepatitis B and is widely used as a vaccine adjuvant and immune enhancer. Global demand for immunomodulatory peptides continues to grow, particularly in infectious disease control, oncology supportive care, and immunocompromised patient management.
