Mechanism record

Thymulin (FTS, facteur thymique sérique) is a zinc-dependent 9-residue chemical sequence secreted by thymic epithelial cells. The Zn²⁺ ion is required for biological activity, apo-thymulin is inactive. It promotes T-cell differentiation by modulating CD4+/CD8+ ratio, enhances NK cell cytotoxicity, and stimulates IL-2 receptor expression on T-lymphocytes. Thymulin levels decline with age, paralleling thymic involution.

Limitations and research boundary

Research use only. Not for human or veterinary use. Public catalog information is limited to chemical identity, analytical documentation, and external reference records.

External records are attributed references. Their presence does not convert a source-reported observation into a product claim.
