What this research studies
We know that the APOE4 gene significantly increases the risk for Alzheimer's disease, but we don't fully understand why. Our team is looking into how APOE4 affects certain fats, called phospholipids, in brain cells, specifically focusing on a molecule called PIP2. We've found that APOE4 can increase an enzyme, synaptojanin 1 (synj1), which breaks down PIP2. This imbalance might harm brain immune cells called microglia, making them less effective at clearing harmful substances and potentially leading to excessive removal of important connections between brain cells. By understanding this pathway, we hope to uncover new ways to protect the brain from APOE4's damaging effects.
Who could benefit from this research
Good fit: Patients with Alzheimer's disease, especially those carrying the APOE4 gene, could potentially benefit from future therapies developed from this foundational research.
Not a fit: Patients whose Alzheimer's disease is not linked to the APOE4 gene or similar phospholipid dysregulation may not directly benefit from this specific line of research.
Why it matters
Potential benefit: If successful, this work could lead to new treatments that target the APOE-synj1-PIP2 pathway to prevent or slow down Alzheimer's disease in individuals with the APOE4 gene.
How similar studies have performed: Previous work by this team has shown that APOE4 affects PIP2 and that reducing synj1 can improve cognitive issues and cell defects in models, suggesting a promising direction for this ongoing work.
