Scientists have made a breakthrough in understanding how a misfolded protein contributes to Parkinson's disease—a discovery that could eventually lead to better treatments for this progressive nervous system disorder affecting millions worldwide.

Researchers found that a protein called α-synuclein, which normally helps neurons communicate, can become dangerous when it changes shape and clumps together. These malformed proteins accumulate in the cerebrospinal fluid and brain tissue, interfering with the brain's natural waste disposal system. Understanding exactly how this protein sabotages the brain's cleanup process is a crucial step toward developing therapies that could slow or prevent Parkinson's progression. Read the full story →

Today's takeaway: By unraveling how disease-causing proteins damage the brain, scientists move closer to new treatments that could help millions living with Parkinson's disease.
