Researchers at the University of Virginia and Johns Hopkins University School of Medicine in Baltimore have developed a new, non-invasive and non-toxic genetic therapeutic technique to restore dopaminergic neuron function in rats suffering from Parkinson’s disease. The technique, which makes use of magnetic-resonance-image-guided ultrasound and brain-penetrating nanoparticles, reverses neurodegeneration thanks to expression of the neurotrophic growth factor GDNF in motor-neuron pathways. A singe injection of the nanoparticles continues to act for at least 10 weeks………
