Arizona State University Scientists describe a process for converting non-neuronal cells into functioning neurons able to take up residence in the brain, send out their fibrous branches across neural tissue, form synapses, dispense dopamine and restore capacities undermined by Parkinson’s destruction of dopaminergic cells.
Neurodegenerative diseases damage and destroy neurons, ravaging both mental and physical health. Parkinson’s disease, which affects over 10 million people worldwide, is no exception. The most obvious symptoms of Parkinson’s disease arise after the illness damages a specific class of neuron located in the midbrain. The effect is to rob the brain of dopamine — a key neurotransmitter produced by the affected neurons.
In new research, Jeffrey Kordower and his colleagues describe a process for converting non-neuronal cells into functioning neurons able to take up residence in the brain, send out their fibrous branches across neural tissue, form synapses, dispense dopamine and restore capacities undermined by Parkinson’s destruction of dopaminergic cells.
The current proof-of-concept study reveals that one group of experimentally engineered cells performs optimally in terms of survival, growth, neural connectivity, and dopamine production, when implanted in the brains of rats. The study demonstrates that the result of such neural grafts is to effectively reverse motor symptoms due to Parkinson’s disease.
