How ancient viruses shaped human DNA

Ancient viral threats through the lens of adaptation in human genomes

NIH-funded research University of Arizona · NIH-11140381

This project looks for signs in human genomes showing which viruses affected our ancestors, to help identify viruses that could threaten people today.

What this research studies

This work looks through large collections of human DNA for genetic "footprints" left by ancient viruses that affected our ancestors. Scientists will use advanced computer tools, including machine learning and ancestral recombination graphs, to find and date those footprints. They will then study how the identified genetic changes altered immune genes and responses. The goal is to spot virus families that caused past epidemics and might threaten people again.

Who could benefit from this research

Good fit: People who have donated DNA to research biobanks or who participate in large genetic studies are the most likely source of data for this work.

Not a fit: Individuals seeking immediate clinical treatment for current infections are unlikely to receive direct medical benefit from this basic genetic research.

Why it matters

Potential benefit: If successful, this work could help public health officials prioritize surveillance, vaccines, and treatments against virus families most likely to spark future pandemics.

How similar studies have performed: Previous studies have found signals of ancient viral adaptation in human genes, but combining ancestral recombination graph methods with machine learning is a newer and less-tested approach.
