How poxviruses are blocked from jumping between species

Novel Translational Control Mechanisms in Host Range Restriction of Poxvirus

NIH-funded research University of Texas Hlth Science Center · NIH-11235028

Researchers are exploring how natural proteins in people and animals block poxviruses like mpox to help prevent future infections.

What this research studies

From my point of view, the team is focusing on two natural proteins called SAMD9 and SAMD9L that can stop poxviruses from multiplying. They will study how these proteins cut specific tRNAs and cause stress in infected cells, and how viral proteins counteract them. The work uses cells and animal models and compares versions of these proteins across different species to understand why some animals carry these viruses while others do not. Results aim to reveal molecular steps that let poxviruses cross species so scientists can better predict and block spillovers.

Who could benefit from this research

Good fit: People with confirmed orthopoxvirus infection (for example, mpox) or individuals willing to donate blood or tissue samples for research would be the most relevant participants.

Not a fit: Those without any exposure risk to poxviruses or people seeking immediate clinical treatment are unlikely to gain direct benefit from this basic science project.

Why it matters

Potential benefit: If successful, this work could improve our ability to predict which animal poxviruses might infect people and point to new antiviral targets to prevent or treat infections.

How similar studies have performed: Prior laboratory studies have identified SAMD9/9L as important viral restriction factors, but turning that knowledge into patient-facing treatments or preventive tools remains largely untested.
