Air pollution and the APOE gene in Alzheimer’s disease
Neurotoxicity of particulate matter and its interaction with APOE in neurodegeneration
Researchers are seeing if tiny particles in air pollution make Alzheimer’s brain damage worse, especially for people with higher-risk APOE gene versions.

What this research studies
This project looks at how tiny airborne particles (particulate matter) may harm brain cells and speed up Alzheimer’s-related neurodegeneration. Scientists will use laboratory Alzheimer’s models and molecular analyses to trace the toxic pathways triggered by pollution. They will examine how different APOE gene versions change vulnerability to that damage and use biological samples to link findings to human disease. The aim is to reveal mechanisms that explain who is more at risk so future prevention or treatments can be targeted.
Who could benefit from this research
Good fit: Ideal participants would include people with or at risk for Alzheimer’s disease—especially those carrying APOE ε4 or living in high air-pollution areas—who can provide clinical information or biological samples.
Not a fit: People without Alzheimer’s risk factors or without meaningful exposure to air pollution are less likely to benefit directly from findings focused on pollution–APOE interactions.
Why it matters
Potential benefit: If successful, the work could reveal pollution-driven pathways and gene–environment links that point to ways to prevent or slow Alzheimer’s disease, particularly for people with risky APOE variants.
How similar studies have performed: Prior human and animal studies have linked air pollution and Alzheimer’s risk genes to worsening brain pathology, but detailed mechanistic gene–environment connections remain relatively novel and are still being worked out.
