Thymulin

Thymulin is a naturally occurring thymic nonapeptide originally isolated from the serum and thymus gland by Dr. Jean-François Bach at the University of Paris. As the primary thymic hormone responsible for T-cell maturation and immune system homeostasis, Thymulin plays a critical role in thymus-dependent immunity, coordinating the differentiation and functional activation of T-lymphocytes across helper (CD4+), cytotoxic (CD8+), and regulatory (Treg) subsets.
