Overview

What Vilon is

About Vilon

Synthetic dipeptide Lys-Glu; modulates T-cell and NK cell activity; reduces age-related immune decline; normalizes cytokine production via epigenetic gene regulation

Vilon is a synthetic dipeptide (Lys-Glu, KE) classified as a Khavinson-class bioregulator originally derived from thymic tissue, proposed to modulate immune function in aging subjects by providing minimal thymic regulatory dipeptide signals that support T-lymphocyte activation and immune homeostasis diminished by age-related thymic involution. As the minimal active dipeptide unit of the Khavinson thymic bioregulator class, vilon is proposed to act through amino acid transporter uptake and modulation of intracellular signaling — including sphingomyelin pathway signal transduction in thymocytes — to restore T-cell activation thresholds and proliferative responses in immune cells from elderly subjects. Research has characterized natural and synthetic thymic peptides including vilon as therapeutic candidates for immune dysfunction, and experimental work has demonstrated that short Khavinson-class peptides modulate thymocyte blast transformation and sphingomyelin pathway signaling in immune cell preparations. Vilon has no FDA approval; evidence derives from Khavinson-series Russian preclinical and observational studies, and it has no regulatory approval in any major Western jurisdiction.

  • Comparative study of the effects of vilon, epithalon, and cortagen on thymocyte proliferation and sphingomyelinase activity

    Bulletin of Experimental Biology and Medicine · 2002

    Research in mouse thymocyte cultures found that vilon produced the most potent comitogenic stimulation of thymocyte proliferation and sphingomyelinase activity compared with epithalon and cortagen, providing mechanistic evidence for its thymopoiesis-promoting activity and relevance to immune restoration in aging.

  • Immunomodulatory peptides from the thymus

    International Journal of Immunopharmacology · 1997

    This review describes the isolation of vilon (Lys-Glu) as the active immunomodulatory dipeptide from thymalin, documenting its activation of T-cell differentiation, cytokine regulatory activity, and comparison with thymogen, establishing it as the low-molecular-weight component responsible for thymalin's immune-modulating and geroprotective properties.
