Vilon (L-Lys-L-Glu) is the simplest Khavinson bioregulator — a dipeptide derived from thymus tissue that modulates immune cell proliferation and differentiation. Animal studies show it inhibits spontaneous tumor growth and increases lifespan in mice.
Vilon is the synthetic minimal sequence identified by Khavinson's team as one of the active components of Thymalin (a thymus extract). At just two amino acids, it's the smallest bioregulator peptide — yet it retains immunomodulatory properties in cell and animal models.
Mimics thymic peptide signaling to support T-cell proliferation and differentiation. May help restore adaptive immune function that declines with thymic involution during aging.
Despite being only two amino acids, Vilon crosses cell and nuclear membranes to interact with DNA regulatory regions, influencing gene expression in immune cells.
In mouse models, Vilon inhibited spontaneous tumor growth — likely through enhanced immune surveillance rather than direct cytotoxicity.
In THP-1 monocyte/macrophage cells, Vilon regulated proliferative activity and inflammatory pathway gene expression (PMC8999041).
Context: Vilon research comes from the Khavinson bioregulator program and peer-reviewed publications including PMC-indexed studies. Evidence is primarily in vitro and animal studies. No large-scale human clinical trials exist.
