MitoCanada partners with MITO2i to fund mitochondrial research that could introduce new therapies for Alzheimer’s disease
Alzheimer’s disease is one of hundreds of illnesses that Canadians suffer from. The disease stems from mitochondrial dysfunction, however, the underlying molecular mechanism and how it contributes to the development of disease remains poorly understood.
Alzheimer’s disease in patients and mouse models exhibits an imbalance between mitochondrial fission and fusion. This change in dynamics within the mitochondria has significant consequences on how electrical signals move from one nerve cell to another as well as how the nerve cells themselves function.
Re-establishing an equilibrium within mitochondrial dynamics and structure may be a potential therapeutic target for recovering mitochondrial function and neuronal homeostasis which is the process by which organisms react to specific conditions while trying to maintain their stability and survival.
Dr. Royeais investigating the significance of Sigma-1-receptors medicines and their impact on mitochondrial function. She hopes her future research will identify whether the FDA approved, pain relieving drug, Pentazocine, can be repurposed for the treatment of Alzheimer’s disease as well as other mitochondrial-specific diseases.

The sisters and their family had never even heard of mitochondrial disease (mito) — and neither had many of the health care practitioners in their hometown of Newfoundland and Labrador, which contributed to the long path to diagnosis.
While Jodi, Erika and their mother, Brenda, all have MELAS, the three of them are affected in different ways.
Despite — or perhaps because of — these challenges, the Young family has developed a rare closeness. “My sister, mom, dad, and I will always have an unspoken bond that comes with experiencing mito,” says Erika. “Mito has definitely brought us all closer together,” agrees Jodi. “Dealing with mito can be extremely isolating, especially here in Newfoundland where there are few resources for anything, let alone a rare disease. This forced us to be closer, because we only had each other.”
As they build their own rich lives as young adults — Jodi is a mitoScholar who’s passionate about entomology(the study of insects) and who’s currently pursuing a PhD in plant-pollinator interactions, and a huge animal lover who finds joy in spending time with her partner and her pets (a dog, birds, sugar gliders, and a snake), while Erika is a soil researcher who loves travelling and partaking in outdoor activities with her spouse and her Australian Shepherd — the sisters remain ever-committed to their parents. “While I no longer live at home, I see my parents almost every day,” says Erika. “The negative consequences of MELAS are ever-present even though I live a full life and am not actively experiencing symptoms of the disease.”
