How emerging bunyaviruses infect brain cells

Mechanisms of Neuronal Infection by Prototype Emerging Bunyaviruses

NIH-funded research University of Pittsburgh at Pittsburgh · NIH-11140309

What this research studies

Researchers will compare three medically important bunyaviruses—La Crosse, Rift Valley fever, and Oropouche—to identify which brain cell types they target and how infection alters the local brain environment. The work uses laboratory neuronal cells and relevant animal models to track viral entry, replication, and the resulting inflammation. Scientists will define viral and host factors that drive neurologic disease and examine the consequences of target cell infection. Findings are intended to reveal points of vulnerability that could guide future diagnostics, antivirals, or vaccines.

Who could benefit from this research

Good fit: Ideal candidates would be people who live in or have traveled to areas where La Crosse, Rift Valley fever, or Oropouche viruses circulate, or patients recovering from suspected bunyavirus encephalitis who could donate clinical samples.

Not a fit: People with non-infectious neurological conditions or who are not at risk of exposure to these specific viruses are unlikely to see direct benefit from this basic laboratory research.

Why it matters

Potential benefit: If successful, this work could point to new targets for treatments, vaccines, or diagnostics to prevent and reduce viral brain infections.

How similar studies have performed: Previous studies have described how individual bunyaviruses infect brain cells, but direct head-to-head comparisons of these three viruses to define common and unique neuropathogenic mechanisms are novel.
