Abstract:
PURPOSE: An increase method of fused protein into living cells or organs by adding pergolide to fused protein in which protein transport domains and therapeutic protein are covalently bonded is provided to drastically enhance infiltration efficiency of the fused protein. CONSTITUTION: An increase method of fused protein into living cells or organs is processed by adding pergolide to fused protein in which protein transport domains and therapeutic protein are covalently bonded. The pergolide is primarily processed in the living cells or organs than the fused protein. A protein transport domain is Tat, PEP-1, oligolysine, oligo arginine or oligo(lysine and arginine). The pergolide is pergolide mesylate. The therapeutic protein is an enzyme which removes the active oxygen species. The therapeutic protein is catalase, superoxide dismutase or glutathione peroxidase. A composition for preventing and treating disease due to oxidative stress and inflammatory diseases comprises the fused protein and pergolide of the enzyme having the active oxygen species.
