What this research studies

Our bodies have a system to clear waste and cholesterol, involving special vessels called lymphatics and immune cells called macrophages. This project looks at how a type of "good" cholesterol, called HDLA1, travels through tissues and interacts with these immune cells to remove cholesterol. We are particularly interested in how these processes work in the brain, specifically in a condition called cerebral amyloid angiopathy, which is related to Alzheimer's disease. By understanding these basic mechanisms, we hope to learn more about how the brain clears harmful substances and how this might go wrong in diseases like Alzheimer's. We use advanced techniques, including a special mouse model, to track these processes in detail.

Who could benefit from this research

Good fit: Patients with cerebral amyloid angiopathy or Alzheimer's disease dementia may eventually benefit from the knowledge gained from this fundamental research.

Not a fit: Patients seeking immediate treatment options or direct clinical intervention will not receive benefit from this basic science project.

Why it matters

Potential benefit: If successful, this work could lead to new ways to understand and potentially treat conditions like cerebral amyloid angiopathy and Alzheimer's disease by improving the brain's waste clearance.

How similar studies have performed: Previous work by this lab has successfully demonstrated how good cholesterol travels through tissues and its role in cholesterol transport.
