Macromolecule intracellular transduction technology based on improved cell-permeable Parkin recombinant protein (iCP-Parkin) has been developed as a protein-based anti-neurodegenerative agent for efficient BBB-penetration to effectively deliver the recombinant protein into the brain. Parkin protein, a dopaminergic neuronal cell death inhibitor, has been fused with a newly developed advanced macromolecule transduction domain (aMTD) and solubilization domain (SD) to increase the solubility / yield and cell- / tissue-permeability of the recombinant protein. In addition, our newly developed aMTD / SD-fused recombinant iCP-Parkin protein has shown BBB-permeability. Both in vitro and in vivo, our iCP-Parkin recombinant protein improved motor skills, a typical phenotype of Parkinson's disease, by increasing dopamine level in the brain by suppressing apoptosis of dopaminergic neuron cells. In conclusion, iCP-Parkin could be applicable in clinical studies as a protein-based anti-neurodegenerative agent to treat Parkinson's disease by protecting dopaminergic neuron cells and regulating the secretion of dopamine.
