Scientists from the Krembil Brain Institute at UHN and the University of Toronto have made a significant discovery related to Parkinson’s disease.

Their study, published in Nature Communications, reveals a protein-protein interaction that plays a role in the development of Parkinson’s disease.

Understanding Parkinson’s Disease

Parkinson’s disease is a neurodegenerative disorder characterized by the accumulation of a protein called α-synuclein (a-syn) in the brain, leading to cell death.

The Research Findings

The researchers identified a peptide that disrupts the interaction between a-syn and a protein subunit called ESCRT-III.

ESCRT-III is part of a cellular pathway involved in protein degradation. By disrupting this interaction, the peptide reduced a-syn levels.

The Role of Endolysosomal Pathway

The researchers discovered that a-syn interacts with a protein called CHMP2B within the endolysosomal pathway.

This interaction prevents the breakdown of a-syn, contributing to its accumulation in Parkinson’s disease.

Testing the Peptide

The research team developed a screening platform to identify peptides that disrupt protein-protein interactions.

They found the a-syn-CHMP2B interaction and tested the peptide in experimental models of Parkinson’s disease.

The peptide restored endolysosomal function, facilitated a-syn clearance, and prevented cell death.

Implications for Parkinson’s Treatment

Dr. Suneil Kalia, one of the researchers, stated that disrupting the a-syn-CHMP2B interaction could prevent a-syn from evading natural clearance pathways in cells.

While more research is needed, this discovery opens up a new avenue for potential Parkinson’s treatments and other related conditions.

Preventing Parkinson’s Disease

While there is no guaranteed way to prevent Parkinson’s disease, certain lifestyle factors may lower the risk:

Regular Exercise: Engaging in regular physical exercise may reduce the risk of Parkinson’s disease and slow its progression.

Healthy Diet: A diet rich in fruits, vegetables, whole grains, and lean proteins may lower the risk of Parkinson’s disease.

Adequate Sleep: Getting enough restful sleep may contribute to a lower risk of developing Parkinson’s disease.

Avoiding Toxins: Limiting exposure to environmental toxins like pesticides and herbicides may reduce the risk of Parkinson’s disease.

Head Protection: Wearing a helmet during activities such as cycling or contact sports can help protect against traumatic brain injuries, which are linked to an increased risk of Parkinson’s disease.

Mental Stimulation: Engaging in mentally challenging activities such as puzzles and reading may lower the risk of Parkinson’s disease.

Stress Management: Finding healthy ways to manage stress, such as meditation or yoga, may be beneficial in reducing the risk of Parkinson’s disease.


The recent discovery of a protein-protein interaction related to Parkinson’s disease offers promising insights into potential treatments.

While further research is needed, these findings could lead to the development of therapies targeting a-syn accumulation.

Individuals can also lower their risk of Parkinson’s disease through lifestyle choices such as regular exercise, a healthy diet, adequate sleep, toxin avoidance, head protection, mental stimulation, and stress management.

It’s essential to consult a healthcare provider for personalized advice regarding Parkinson’s disease prevention and management.
