Targeting PTPN22 to strengthen antiviral defenses
Chemical Inhibition PTPN22 to boost anti-viral immunity
The team is developing drugs that target the PTPN22 protein to strengthen antiviral immunity in people who struggle to clear persistent viral infections.

What this research studies
Researchers will make pieces of the PTPN22 protein and use those pieces to screen chemical libraries for molecules that mimic a naturally protective genetic variant. Hits from the screen will be refined with computational chemistry and tested in lab assays and mouse models that previously showed improved viral clearance with the protective variant. The work is done using shared cores at the University of Kansas for protein production, infectious disease assays, and computational chemical biology. If a promising compound emerges, it could advance toward further preclinical development and eventually human testing.
Who could benefit from this research
Good fit: People with chronic or persistent viral infections who have difficulty clearing viruses may be the eventual candidates for treatments developed from this work.
Not a fit: People without viral infections, or whose immune problems are unrelated to the PTPN22 pathway, are unlikely to benefit from this early-stage preclinical project.
Why it matters
Potential benefit: If successful, this work could lead to new drugs that help people clear chronic or persistent viral infections more effectively.
How similar studies have performed: Mouse studies show a naturally occurring PTPN22 variant improved antiviral clearance, but chemically targeting the same site is a new approach that has not yet been proven in humans.
