Meccanismo d'azione

KPV

KPV is the C-terminal fragment of α-melanocyte-stimulating hormone (α-MSH). In preclinical models the inflammation-modulating activity is attributed predominantly to inhibition of the NF-κB and MAP-kinase signalling pathways, accompanied by reduced release of pro-inflammatory mediators. Cellular uptake via the peptide transporter PepT1 has also been described. The precise molecular mechanisms are not conclusively understood and not confirmed in humans.

Thymalin

Thymalin is a complex of multiple polypeptides extracted from bovine or calf thymus. Postulated mechanisms include modulation of T-lymphocyte maturation, influence on interleukin profiles and stimulation of cellular immune response. Being a multi-component preparation, individual mechanisms are difficult to disentangle. Khavinson and colleagues from St Petersburg have described the mechanism over decades in Russian publications.

Frequently asked questions

What is the difference between KPV and Thymalin?: KPV is classified as "Guarigione", while Thymalin is classified as "Guarigione". KPV: KPV is the C-terminal tripeptide (lysine-proline-valine) of the hormone α-MSH, corresponding to its positions 11–13. In cell and rodent models an inflammation-modulating activity has been described, primarily via inhibition of the NF-κB signalling pathway. The evidence is drawn almost exclusively from preclinical work (cell culture and mouse); controlled human studies are essentially absent. KPV is not an approved medicinal product. Thymalin: Complex of low-molecular polypeptides extracted from calf thymus. Approved in Russia since the 1970s as an immunomodulator. The exact composition is not standardised like a synthetic single peptide; Western controlled studies are largely absent. This page contrasts both neutrally and source-based — with no usage or dosing recommendation.
Which peptide is better supported by science, KPV or Thymalin?: The highest available evidence level is "Modello animale" for KPV and "Studio sull'uomo" for Thymalin. A higher evidence level means more robust data, but says nothing about suitability for an individual. The full body of evidence is on each peptide's own page.
What is the legal status of KPV and Thymalin in Germany and the United States?: Germania: KPV — Non approvato, Thymalin — Non approvato. Stati Uniti: KPV — Solo ricerca, Thymalin — Non approvato. These are factual summaries with source and review date on the individual pages.
