Immune Cells at the Brain's Borders and Alzheimer's Disease
Parenchymal border macrophages in AD and CAA
This research explores how special immune cells at the brain's borders, called parenchymal-border macrophages, may play a role in Alzheimer's disease by affecting how fluids clear waste from the brain.

What this research studies
Many brain conditions, including Alzheimer's disease, are connected to issues with the immune system. This research focuses on special immune cells called parenchymal-border macrophages (PBMs) that live at the edges of the brain and interact with the fluid that surrounds it. Our early findings suggest that when these PBMs don't work properly, it can disrupt how fluids clear waste from the brain and lead to a buildup of proteins, similar to what is seen in aging and Alzheimer's. We are exploring how these PBMs are renewed and how they contribute to the disease process, hoping to find new ways to help patients.
Who could benefit from this research
Good fit: This foundational research is not directly recruiting patients but aims to understand disease mechanisms relevant to individuals with Alzheimer's disease or those at risk.
Not a fit: Patients seeking immediate treatment options would not directly benefit from this early-stage, mechanistic research.
Why it matters
Potential benefit: If successful, this research could lead to new treatments for Alzheimer's disease by targeting these specific immune cells and improving brain fluid dynamics.
How similar studies have performed: While the specific role of parenchymal-border macrophages in Alzheimer's is a relatively new area of focus, research into immune system involvement in neurodegenerative diseases has shown promising avenues for intervention.
