What this research studies
This project looks at how molecular 'chaperones' and the cell's cleanup systems keep proteins folded and remove damaged ones, because when this fails proteins can clump and harm brain cells. Using yeast and laboratory cell models, the team will focus on how redox balance (the cell's antioxidant systems like thioredoxin and glutathione) changes where and how proteins are handled. They will examine specific components such as the sequestrase Hsp42, the proteasome, and autophagy pathways to see how these systems cooperate or fail under stress. Findings may point to biological steps that could be targeted to slow or prevent the protein clumping seen in Alzheimer's, Parkinson's, and Huntington's diseases.
Who could benefit from this research
Good fit: People with Alzheimer's disease, Parkinson's disease, or Huntington's disease, or family members interested in supporting related research or future sample donation, could be future beneficiaries of this work.
Not a fit: People seeking an immediate new treatment or those without protein-misfolding conditions are unlikely to benefit directly from this basic laboratory research in the short term.
Why it matters
Potential benefit: If successful, the work could reveal new molecular targets for therapies that prevent or reduce harmful protein clumps in neurodegenerative diseases.
How similar studies have performed: Similar laboratory studies have shown promise in identifying chaperone and proteostasis pathways as targets in cell and animal models, but translating these findings into human treatments remains early and unproven.
