After using the chemical to kill dopamine neurons in the mice, researchers silenced PTB.
They discovered 30 percent of astrocytes turned into neurons.
In addition, these newly-generated neurons seemed to grow normally and even began to send connections to other parts of the brain, like normal neurons.
When the researchers looked at mouse behaviour, they also found silencing PTB completely restored movement function.
Moreover, even though the PTB-silencing treatment was only administered once, the mice did not show any symptoms of Parkinson’s disease for the remainder of their lifetime.
