Thymosin Beta-4 (Tβ4) is an endogenous 43-amino-acid peptide regarded as the principal intracellular actin-sequestering factor, involved in cell migration, neovascularisation and tissue regeneration. It has been studied in dry eye, corneal and wound healing, and cardiac repair (RegeneRx programmes, RGN-259). Thymosin Beta-4 is NOT an approved drug; robust human efficacy data are limited. The grey-market TB-500 is a synthetic fragment/analogue and is distinct from it.
Thymosin Beta-4 forms a 1:1 complex with monomeric (G-)actin and is regarded as the principal actin-sequestering factor in many cell types, thereby influencing cytoskeletal dynamics and directional cell migration. Preclinical models additionally describe effects on endothelial cell migration and neovascularisation, as well as activation of survival signalling pathways (including ILK/Akt). The mechanistic evidence derives predominantly from cell-culture and animal models.
