Cone photoreceptor dysfunction may precede other measurable symptoms in Huntington´s Disease mice

What is it about?

We showed that the retina of the eye (where visual sensory begins) is affected in Huntington´s Disease (HD) associated pathology in mice. Our findings, and similar findings by others in HD mice and patients, suggest that the retinal pathology might be used as an indicator of disease progression and perhaps as a biomarker for drug trials.

Why is it important?

The involvement of visual pathology in Huntington´s Disease has been suggested already over two decades ago, but reports has been inconsistent. New line of research (including ours) verify that Huntington´s pathology indeed affect the retina.
