Role of mitochondrial c-Src kinase in Alzheimer’s disease
Project Overview
Mitochondrial dysfunctions are observed before and during the progression of Alzheimer's disease (AD). It is important to understand how the regulation of mitochondria is impaired in AD. The c-Src kinase has appeared as an important regulator of mitochondria. The aim of this research program is to explore, for the first…

Project Overview
New neuroimaging techniques enable us to measure the key hallmarks of Alzheimer's disease (AD) pathology before symptoms appear. The AD pathologic process is known to begin decades before the appearance of dementia symptoms such as memory or language deficits. Therefore, Dr. Villeneuve will use these new imaging methods alongside existing…

Project Overview
Alzheimer’s disease (AD) is a severely disabling illness with biological causes that are not well understood. Abnormalities in gene function impacts brain activities and could cause AD. Enhancers are elements in the DNA code that enable the complex expression of genes. Epigenetic marks control enhancers, which in turn creates specific…

Project Overview
In Alzheimer s disease (AD), critical synaptic connections between neurons disintegrate and cells die. The brains of individuals with AD accumulate plaques of a protein fragment called AÎ that disrupt synapse function and cause neuronal death. Dr. Kennedy and his team will study a protein called netrin-1 that promotes cell…

Project Overview
The existence of different strains of misshapen proteins in the brains of Alzheimer’s disease (AD) patients is emerging as an obstacle to the development of effective treatments. Recent research has revealed that the proteins that accumulate in the brain during AD are reminiscent of prions, which cause rare brain diseases…
