Lupus Prize: Immune Sensor Discovery Sparks Hope
11 Nov
Summary
- Researchers discovered how a key immune regulator controls TLR7 activity.
- Genetic changes in this pathway were linked to lupus development.
- Findings offer new targets for precise lupus treatment strategies.
The Lupus Research Alliance presented the 2026 Lupus Insight Prize to Drs. Gregory Barton and Olivia Majer for their significant contributions to understanding lupus. Their research unveiled the crucial role of UNC93B1 in controlling TLR7, an immune system sensor that recognizes viral RNA.
Their findings, published in 2024, identified numerous UNC93B1 mutations that amplify TLR7 activity, with several being present in individuals with lupus. Experiments with mice engineered to carry these mutations demonstrated they can directly cause lupus-like disease, establishing UNC93B1 as a critical safeguard.
Dr. Majer further elucidated how a specific UNC93B1 mutation disrupts the degradation of TLR7, leading to its accumulation in immune cells and hyperresponsiveness. This work deepens the understanding of immune balance and provides a foundation for developing more precise diagnostic and therapeutic approaches for lupus patients.
The discoveries pave the way for matching patients with mutations to targeted therapies, potentially improving diagnosis and treatment outcomes. The award ceremony took place at ACR Convergence 2026 in Orlando.
