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.
A nonapeptide produced by thymic epithelial cells that plays a central role in T-cell maturation and immune system regulation. Levels decline markedly with age as the thymus involutes. Studied for immune reconstitution in aging and chronic illness.
