02Mechanism of Action

Thymulin is a thymic nonapeptide whose biological activity in research models is strictly zinc-dependent — the zinc-bound form is the active species. It is studied for its role in thymocyte differentiation and T-cell development.

Research also examines its cytokine-modulating activity and its position in neuroendocrine-immune signaling networks.
