Scientists have shown that it is possible to restore mobility in those with Parkinson's Disease, offering hope for new treatments.
Researchers at the Centre for Research and Advanced Studies in Mexico City used stem cells to generate dopaminergic nerve cells and reactivate the production of dopamine in the brains of rats with symptoms of shaking palsy or Parkinson's Disease, thereby restoring mobility.
"Our treatment has allowed us to recover these motor impairments, which is associated with the recovery of neurons and dendritic spines of striatal neurons, which is the first thing that gets damaged in Parkinson's Disease," explained the study's leader, Aceves Ruiz.
The study focused on a region of the brain known as the basal ganglia, which contains the nerve cells that produce neurotransmitters, including dopamine.
A lack of dopamine is a cause of motor problems in those with Parkinson's, as the neurotransmitter allows messages to be sent to the parts of the brain that coordinate movement.
Although there is currently no treatment for the condition, a number of drugs and other therapies can lessen the severity of Parkinson's Disease.
