Protective Gene Discovered Against Alzheimer's
A Columbia University study reveals a gene that reduces the risk of Alzheimer’s by up to 70%, paving the way for new therapies
A Remarkable Scientific Discovery
An extraordinary breakthrough in Alzheimer’s treatment has sparked new hopes for addressing the disease. Researchers at Columbia University have identified a gene that reduces the risk of developing Alzheimer’s by up to 70%, opening up potential new targeted therapies.
The Crucial Role of Fibronectin
The protective genetic variant is located in a gene that produces fibronectin, a key component of the blood-brain barrier. This supports the hypothesis that brain blood vessels play a fundamental role in Alzheimer’s pathogenesis and could be essential for new therapies. Fibronectin, typically present in limited quantities in the blood-brain barrier, appears to exert a protective effect against Alzheimer’s by preventing excessive accumulation of this protein in the membrane.
Promising Therapeutic Prospects
According to Caghan Kizil, co-leader of the study, this discovery could lead to the development of new therapies that mimic the protective effect of the gene. The goal would be to prevent or treat Alzheimer’s by harnessing fibronectin’s ability to remove toxins from the brain through the blood-brain barrier. This new therapeutic perspective offers concrete hope for millions of people affected by this neurodegenerative disease.
Richard Mayeux, co-leader of the study, expresses optimism about the future prospects. Studies on animal models have confirmed the effectiveness of fibronectin-targeted therapy in improving Alzheimer’s. These results pave the way for a potential targeted therapy that could provide a strong defense against the disease. Additionally, the identification of this protective variant could lead to a better understanding of the underlying mechanisms of Alzheimer’s and its prevention.
What is Alzheimer’s
Alzheimer’s is a chronic degenerative disorder of the central nervous system that involves progressive decline in cognitive abilities, memory, and rational faculties. It is the most common form of dementia, primarily affecting elderly individuals, although it can also manifest at relatively young ages in exceptional cases. The hallmark of Alzheimer’s lies in the presence of amyloid plaques and tau protein tangles in the brain, which cause damage and destruction of nerve cells. This results in symptoms such as memory loss, mental confusion, difficulties in speech and thought organization, as well as behavioral and emotional problems. Currently, there is no definitive cure for the disease, but research efforts continue to seek new treatments aimed at slowing the progression of the condition and improving the quality of life for patients. The discovery of this protective variant thus constitutes a significant step in combating this devastating condition.
