A common hallmark of ALS is the presence of proteins, such as FUS or TDP-43, that have left their proper home in a cell, become misshapen and possibly no longer function properly. Drs. Stepanova and Wille’s project is based on what’s called the Prion Hypothesis, the idea that these misfolded proteins can transmit their abnormal structure to normal versions of the same protein, creating clumps or aggregates that spread throughout the nervous system.
Dr. Stepanova’s lab will use computational methods to analyze these aggregates in ALS-specific proteins. In doing so, she hopes to find areas of the complex shapes for which an antibody could be made.
Dr. Wille’s team will then take her data to attempt to create antibodies that could bind to and, theoretically, stop the misshapen proteins from spreading their abnormal shape.
This process – analyzing misfolded proteins and creating disease-specific antibodies – is one the collaborators have used before in work on other neurodegenerative diseases, such as Alzheimer’s or Parkinson’s. It’s the first time they will take this approach to ALS.
If successful, the project could be the first step in validating new ALS treatment sites or new biomarkers.
Working with Dr. Wille has allowed Dr. Stepanova to bring her theoretical expertise to experiments with possible clinical impact.
“Dr. Stepanova and I have collaborated for a long time on the theoretical side,” Dr. Wille says. “My team and I are the ones who try to translate things into practical experiments.”
By bringing together their complementary skills, the pair look forward to contributing new knowledge to the field of ALS research.
“This is truly what’s important to us,” says Dr. Viviane Poupon, President and CEO of Brain Canada. “Collaboration and knowledge sharing to advance brain research and magnify the potential for impact.”
“Our goal is to find insights that would be interesting, enriching, and useful for the community on the way toward the development of new treatments of ALS,” Dr. Stepanova says. “And we will do our best to achieve whatever we can in two years.”
