What is Thymosin Alpha-1?

Thymosin Alpha-1 (Tα1 — Thymalfasin (28-aa thymic peptide)) is a 28-amino acid N-terminally acetylated thymic peptide. Naturally occurring thymic peptide activating TLR2 and TLR9 on dendritic cells and T-cells, promoting type I IFN production in plasmacytoid dendritic cells, Th1 polarisation, T-cell maturation in thymus, and NK cell cytotoxicity. Approved in 35+ countries as thymalfasin. N-terminal acetylation required for activity.

Research Applications

TLR2/TLR9 Signalling

Innate immune activation via toll-like receptor pathways

Type I Interferon

IFN-α/β production in plasmacytoid dendritic cells

T-Cell Maturation

Thymic maturation, CD3/CD4/CD8 upregulation on thymocytes

Th1 Polarisation

Cell-mediated immunity vs humoral — IL-12, IFN-γ research

NK Cell Activation

Natural killer cell cytotoxicity — antitumour and antiviral
