Understanding how the immune system affects Alzheimer's disease

Rosie Henn is examining how a high-fat diet can affect the immune system and lead to brain inflammation. Her current research is using animal models that are fed increased amounts of fat to see how it activates microglia cells. Microglia are immune system cells that normally protect neurons in the brain and enable healthy communication between neurons. Microglia malfunction in AD brains may contribute to cognitive impairment.

For her residency, Henn plans to pursue a path in adult neurology.
