What this research studies

We are looking into whether a long-term, low-level infection with specific Bacteroides bacteria contributes to Alzheimer's disease. Our previous work in animal models showed that these bacteria can increase amyloid plaques, a hallmark of Alzheimer's. We also found that these bacteria are more common in people with Alzheimer's and are linked to markers of gut inflammation. This suggests a direct connection to human disease, and we are working to understand the exact ways these bacteria might affect brain changes seen in Alzheimer's.

Who could benefit from this research

Good fit: This foundational research is not currently recruiting patients, but future studies based on this work may seek individuals with Alzheimer's disease or those at risk.

Not a fit: Patients without Alzheimer's disease or related risk factors may not directly benefit from this specific research focus.

Why it matters

Potential benefit: If successful, this work could lead to new ways to prevent or treat Alzheimer's disease by targeting specific gut bacteria.

How similar studies have performed: Our group was the first to show that Bacteroides can increase amyloid plaques in animal models, indicating a novel and promising area of investigation.
