Modulation of the Immune Response by STAT1

Signal transducer and activator of transcription 1 (STAT1) is a transcription factor activated by type I and II interferons. This response needs to be fine-tuned because diminished or excessive STAT1-mediated signaling leads to enhanced susceptibility to viral, bacterial, and fungal infections and the development of autoimmune diseases.

Using loss and gain of function models, the Bettelli Lab is currently investigating how STAT1-mediated signaling modulates the function of different immune cells and participates in the pathogenesis of different autoimmune diseases.
