Understanding the APOE4 Gene and Alzheimer's Disease
The APOE4 gene is linked to a significantly increased risk of Alzheimer's disease, with individuals carrying two copies facing an even higher risk. Current research suggests that while many people know their APOE genotype, effective treatment options are still limited. Scientists focus on the role of APOE4 in the brain, where it impacts cholesterol transport and contributes to the formation of amyloid plaques and tau tangles, both hallmarks of Alzheimer’s. Strategies are being explored to either block or mitigate the effects of this gene, including antisense therapies that degrade harmful RNA and gene therapy aimed at delivering a protective version of the gene.
