Key Findings
- All three peptides can stimulate IL‑2 mRNA production in mouse splenocytes in vitro.
- Vilon (Lys‑Glu) and Epithalon (Ala‑Glu‑Asp‑Gly) are more potent than Cortagen (Ala‑Glu‑Asp‑Pro).
- The magnitude of IL‑2 induction depends on peptide concentration and exposure time.
Practical Outcomes
- For DIY health enthusiasts, this study offers little direct guidance because it was done in mouse cells and does not provide dosage, safety, or human data. It suggests Cortagen might have a mild immune‑modulating effect, but any real‑world use would require far more research before it can be considered actionable.
Summary
In a lab test using mouse immune cells, three short synthetic peptides (Vilon, Epithalon, and Cortagen) were able to turn on a gene that makes the immune‑boosting protein interleukin‑2. Vilon and Epithalon were the strongest, while Cortagen had only a modest effect. The response changed with how much peptide was used and how long the cells were exposed.
Abstract
Synthetic peptides Vilon (Lys-Glu), Epithalon (Ala-Glu-Asp-Gly), and Cortagen (Ala-Glu-Asp-Pro) in vitro activated interleukin-2 mRNA synthesis in splenocytes from CBA mice in the absence of specific inductors. The intensity of interleukin-2 mRNA synthesis in splenocytes depended on the type, concentration, and duration of treatment with the peptides. Vilon and Epithalon were most potent, while Cortagen produced a less pronounced effect on interleukin-2 mRNA synthesis.
