How Rift Valley fever virus reaches the brain

Neuropathogenesis of Rift Valley fever virus

NIH-funded research University of Pittsburgh at Pittsburgh · NIH-11172450

What this research studies

This research uses mouse models that mimic a mosquito bite and lab-grown cells to trace how Rift Valley fever virus gets from the skin into the central nervous system. Scientists will inject virus into the mouse footpad to simulate a bite and follow whether the virus crosses the blood–brain barrier, travels inside immune cells, or moves along nerves. They will study how inflammation and damage to endothelial cells affect barrier function and use in vitro experiments to pinpoint molecular steps in that process. Understanding these routes aims to reveal targets for vaccines or drugs that could stop the virus from reaching the brain.

Who could benefit from this research

Good fit: People living in or traveling to areas where Rift Valley fever occurs, or those at risk of mosquito exposure, are the kinds of patients who could benefit from the findings.

Not a fit: Because this is lab-based animal research, patients currently seeking treatment or immediate therapy will not receive direct benefit or clinical care from this grant.

Why it matters

Potential benefit: If successful, this work could identify ways to prevent or treat the dangerous brain infections caused by Rift Valley fever virus.

How similar studies have performed: Similar animal and cell-model approaches have clarified how other viruses reach the brain, but the exact routes used by Rift Valley fever virus are still not well defined.
