Thymulin — Research Overview

Also known as: Facteur Thymique Serique, FTS, Serum Thymic Factor

A zinc-dependent nonapeptide hormone secreted exclusively by thymic epithelial cells. Thymulin plays a central role in T-lymphocyte maturation and immune regulation, and its circulating levels decline sharply with age — paralleling the age-related involution of the thymus. Studied for immune restoration, autoimmune modulation, and anti-inflammatory applications.
