Scientific overview
Thymosin Beta-4 is a 43-amino acid polypeptide that sequesters G-actin monomers, regulating actin polymerization for cell migration and tissue remodeling. Promotes angiogenesis through VEGF upregulation. Anti-inflammatory properties stem from NF-κB inhibition and reduced pro-inflammatory cytokines (IL-1β, TNF-α). Crosses the blood-brain barrier with demonstrated neuroprotective properties.
