About Thymosin Alpha-1
Tα1 modulates both innate and adaptive immune responses by stimulating the differentiation and maturation of T-cells, dendritic cells, and natural killer cells. It upregulates MHC class I and II expression, enhancing antigen presentation. It also promotes the production of key cytokines including interferon-γ and interleukin-2, which are central to immune surveillance.
About Thymulin
Zinc-dependent peptide that promotes T-lymphocyte differentiation, enhances natural killer cell activity, and regulates cytokine balance. Requires zinc cofactor for biological activity.
