By reprogramming skin cells from Parkinson’s disease patients with a known genetic mutation, researchers at the Salk Institute for Biological Studies have identified damage to neural stem cells as a powerful player in the disease. The findings, reported online October 17th in Nature, may lead to new ways to diagnose and treat the disease.
The scientists found that a common mutation to a gene that produce the enzyme LRRK2, which is responsible for both familial and sporadic cases of Parkinson’s disease, deforms the membrane surrounding the nucleus of a neural stem cell. Damaging the nuclear architecture leads to destruction of these powerful cells, as well as their decreased ability to spawn functional neurons, such as the ones that respond to dopamine.
