This invention relates to a
fusion protein that specifically binds to the extradomain B of
fibronectin (EDB-FN) and
transforming growth factor β (TGFβ), and its uses. More specifically, it relates to a
fusion protein comprising a polypeptide that specifically binds to EDB-FN and a polypeptide that specifically binds to TGFβ, and its uses. The
fusion protein of this invention achieves direct localization of TGFβ inhibition within the
tumor microenvironment by immobilizing TGFβ, which is important for anti-tumor immune responses, in the
extracellular matrix, ensuring local rather than systemic action. It not only exhibits excellent anti-tumor effects in various
cancer types, but also, due to the rigidity of the
extracellular matrix, demonstrates excellent anti-tumor effects in
pancreatic cancer, where traditional TGFβ inhibitors are ineffective. Therefore, it can be usefully applied to the prevention or treatment of
cancer.
