Scientists Succeed in Reversing Parkinson’s Symptoms in Mice


The findings of two recent studies give hope that the disease could one day be reversed in humans—but experts warn that this complex disease will likely need multiple complementary treatments.

In that context, Double’s team’s findings could be complemented by recent research from Stanford University focused on restoring communication between neurons in a subtype of Parkinson’s linked to mutations in the gene responsible for producing an enzyme called LRRK2. The team led by Stanford neuroscientist Suzanne Pfeffer proposed that inhibiting the excessive activity of this enzyme could stabilize symptoms, especially if detected in early stages. It is estimated that the number of Parkinson’s cases worldwide could exceed 25 million by 2050, which would represent a 112 percent increase over 2021 figures, according to projections published in the British Medical Journal.
