Victoria AdolphusResearchers at the University of Cambridge have made a groundbreaking discovery in the fight against dementia. A commonly used glaucoma drug, methazolamide, has been found to effectively clear tau protein build-up in the brain, a key factor in dementias such as Alzheimer’s disease.
The Study:
Using zebrafish and mice models, scientists screened over 1,400 clinically approved drugs and identified methazolamide as a potential treatment for tauopathies. The study, published in Nature Chemical Biology, demonstrated that methazolamide:
- Reduced tau protein build-up in zebrafish and mice.
- Improved cognitive function and reduced brain degradation in affected mice.
Understanding Tauopathies:
Tauopathies are neurodegenerative disorders characterized by tau protein accumulation in brain nerve cells. This includes:
- Alzheimer’s disease
- Pick’s disease
- Progressive supranuclear palsy
- Chronic traumatic encephalopathy
The Potential of Methazolamide:
Methazolamide’s ability to inhibit carbonic anhydrase enzymes helps cells eliminate tau protein build-up. This breakthrough opens up new avenues for:
- Repurposing existing drugs to treat dementia.
- Rapid clinical trials for methazolamide.
Expert Insights:
“Zebrafish provide a much more effective and realistic way of screening drug compounds than using cell cultures.” – Dr. Ana Lopez Ramirez
“We were excited to see that methazolamide reduces levels of tau in the brain and protects against its further build-up.” – Dr. Farah Siddiqi
What’s Next:
Clinical trials will be crucial in determining methazolamide’s efficacy in humans. If successful, this glaucoma drug could offer new hope for dementia patients.
