Research using zebrafish has revealed how key brain cells that are damaged in people with Parkinson's disease can be regenerated.
The findings offer clues that could one day lead to treatments for the neurological condition, which causes movement problems and tremors.
Parkinson - Occurs - Nerve - Cells - Brain
Parkinson's occurs when specialised nerve cells in the brain are destroyed. These cells are responsible for producing an important chemical called dopamine.
When these cells die, or become damaged, the loss of dopamine causes body movements to become impaired. Once these cells are lost from the human brain, they cannot be repaired or replaced.
Zebrafish - Nerve - Cells - Stem - Cells
In zebrafish, however, dopamine-producing nerve cells are constantly replaced by dedicated stem cells in the brain, the researchers found.
The team, led by the University of Edinburgh,...
