How the immune system controls West Nile virus in the brain

Innate Immune Mechanisms Controlling Flavivirus Neurovirulence

['FUNDING_R01'] · UNIVERSITY OF MINNESOTA · NIH-11181639

What this research studies

Researchers will use newly developed mouse models and engineered forms of West Nile virus to find which cells start the immune response in the body and which brain cells are targeted. They will map gene activity and immune signals at single-cell and in-tissue (spatial) resolution, and examine epigenetic changes that shape immune behavior. The team aims to learn how the virus crosses into the central nervous system and how early immune responses lead to longer-term brain inflammation and damage. That detailed molecular map is intended to reveal points where future treatments could prevent or reduce neurologic complications.

Who could benefit from this research

Good fit: People who have had West Nile virus infection or who develop neurological symptoms after exposure to the virus are the most relevant population for future clinical translation of these findings.

Not a fit: Patients with unrelated neurological conditions or those needing immediate clinical treatment should not expect direct benefits from this lab-based research right now.

Why it matters

Potential benefit: If successful, this work could reveal targets to prevent or reduce brain infection and long-term neurological damage from West Nile virus.

How similar studies have performed: Prior research has identified some immune factors in West Nile virus infection, but this project applies newer mouse models and high-resolution single-cell and spatial methods to provide more detailed and novel insights.
