Protein Plaques in Neurodegeneration Actively Drain Brain Cell Energy, Study Finds

Groundbreaking research from Rice University has shed new light on the role of protein plaques in neurodegenerative diseases like Parkinson’s. According to the study led by Pernilla Wittung-Stafshede, these protein clumps—long thought to be just waste material—actually behave as enzymes within the brain. They actively break down ATP, the molecule responsible for supplying energy to brain cells.

This discovery changes how scientists understand neurodegeneration. Instead of seeing plaques as harmless debris, researchers now recognize them as active agents that drain crucial energy from brain cells. This energy depletion could accelerate cell death and worsen diseases like Parkinson’s. The new findings may open doors for therapies that target the enzymatic activity of these plaques, potentially slowing or stopping progression of neurodegenerative disorders.

What does this mean for future research?

With this knowledge, scientists can develop new strategies to protect brain cells by inhibiting the harmful enzyme-like actions of protein plaques. The study encourages further investigation into how stopping ATP breakdown might preserve brain health and delay the onset of neurodegenerative symptoms.
