Epitalon
Postulated mechanisms include modulation of gene expression in pinealocytes, telomerase activation (observed in cell culture studies) and influence on melatonin synthesis. A defined primary receptor is not established; the mechanistic basis rests on in-vitro and animal data from the Khavinson group.
Thymosin Alpha-1
Thymosin Alpha-1 is an N-terminally acetylated peptide originally isolated from the thymus. It modulates T-lymphocyte maturation and function and acts on dendritic cells via Toll-like receptors (TLR9 / TLR2). In preclinical and some clinical studies, increased interferon-gamma responses and altered T-cell subpopulations have been reported.
