Targeting toxic HTT1a could be the key to treating Huntington's disease

Summary

This Nature Review article explains how targeting a short, harmful form of the huntingtin gene called HTT1a could help researchers develop better treatments for Huntington's disease. Two new studies in mice found that reducing HTT1a lowered the build-up of harmful huntingtin protein in the brain and improved some of the changes in gene activity linked to the disease.

The findings suggest that targeting HTT1a could be more effective than simply lowering the full-length huntingtin gene message. However, the studies were carried out in mice, so more research is needed to find out whether this approach could work safely and effectively in people.
