Scientists have cracked the code on deadly brain cell clumps that destroy millions of American families through ALS and Huntington’s disease.
Story Highlights
- University at Buffalo researchers solved how toxic RNA clusters form in brain cells and demonstrated method to dissolve them
- Breakthrough targets ALS and Huntington’s disease using engineered antisense oligonucleotides to break apart previously irreversible clumps
- Study published in Nature Chemistry represents first direct evidence of cluster formation mechanism in living cells
- Research funded by NIH and St. Jude opens new pathway for treating neurodegenerative diseases affecting thousands of Americans
Breakthrough Discovery Reveals RNA Cluster Formation
University at Buffalo researchers led by Dr. Priya Banerjee have identified the precise mechanism behind harmful RNA cluster formation in brain cells. These toxic aggregates act as molecular sponges, disrupting normal cellular function and driving the progression of devastating neurodegenerative diseases. The August 2025 study published in Nature Chemistry provides the first direct evidence of how liquid-like RNA-protein droplets transition into solid, irreversible clusters that kill neurons.

Revolutionary Treatment Method Shows Promise
The research team demonstrated that engineered antisense oligonucleotides can successfully dissolve these previously irreversible RNA clusters in living cells. Dr. Banerjee emphasized the dual breakthrough: “We not only figured out how these clusters form but also found a way to break them apart.” This targeted molecular intervention represents a fundamentally new approach to treating ALS, Huntington’s disease, and related neurodegenerative disorders that currently have no cure.
Federal Investment Supports Critical Medical Research
The groundbreaking research received essential funding from the National Institutes of Health and St. Jude Children’s Research Hospital. This federal investment in American biomedical research demonstrates the importance of supporting domestic scientific innovation that directly benefits American families suffering from devastating diseases. The collaboration between major research institutions showcases how proper government funding can accelerate medical breakthroughs without wasteful spending.
Hope for American Families Fighting Devastating Diseases
The discovery offers genuine hope for thousands of American families battling ALS and Huntington’s disease. These conditions currently have no effective treatments, leaving patients and their loved ones facing inevitable decline and death. The research provides a new molecular target for drug development, potentially leading to therapies that could slow or halt disease progression. However, extensive animal testing and clinical trials remain necessary before treatments reach patients.
While translation to human therapy requires further validation, this breakthrough represents significant progress in understanding and potentially treating neurodegenerative diseases. The findings may also inform therapeutic strategies for other conditions involving pathological protein aggregation, including Alzheimer’s disease and frontotemporal dementia, expanding the potential impact for American patients and families.
