Patients with Huntington’s disease deteriorate physically, cognitively, and emotionally. There is no cure for the inherited illness, but scientists may have found a way to slow down the onset of symptoms. Researchers in Quebec increased the expression of a molecule known as pre-enkephalin (pENK) in a mouse model of Huntington’s disease (HD) and saw promising results.

Since reduced expression of pENK is a hallmark of the disease, and neurons containing this molecule are some of the first cells to die in the brains of HD patients, the researchers hypothesized that an HD brain over-expressing pENK might have beneficial results. Their study offers the first evidence that increased pENK expression leads to a delay in muscle dysfunction, improved motor activity, memory, and lower anxiety in early-onset HD.
