Targeting the FOXP3-T-bet interaction to restore Treg stability in IFN-γ-driven autoimmunity.
Disrupting the FOXP3-T-bet interaction impairs Treg stability and promotes IFN-γ-driven Th1 inflammation in IPEX syndrome, with a small molecule restoring this interaction.
- Why it matters: Understanding how FOXP3 mutations cause Treg dysfunction is crucial for developing targeted therapies for autoimmune diseases like IPEX, where immune regulation fails.
- What they did: Researchers used genetic models and AI-driven virtual screening to identify FM029, a small molecule that enhances FOXP3-T-bet interaction, reducing IFN-γ production and inflammation in mice.
- The result: Pharmacologically stabilizing the FOXP3-T-bet interaction with FM029 suppressed Th1 inflammation, demonstrating a promising strategy to treat IFN-γ-driven immune disorders by maintaining Treg stability.
