How STAT1 and STAT3 proteins stay active and trigger autoimmune problems

Mechanisms of STAT1 and STAT3 canonical and persistent activation in physiology and disease

NIH-funded research University of Alabama at Birmingham · NIH-11291853

This project looks at how two immune proteins, STAT1 and STAT3, become persistently active in people with autoimmune and immune‑deficiency conditions so treatments can be improved.

What this research studies

From a patient perspective, scientists will use advanced imaging and lab techniques to see how STAT1 and STAT3 move into cell nuclei and turn on genes. They will combine cryogenic electron microscopy with biochemical, biophysical, and cell experiments to reveal the molecular steps that keep these proteins switched on. The work focuses on gain‑of‑function changes in STAT1 and STAT3 that are linked to autoimmunity and infection risk. Understanding these steps could point to ways to dial down harmful immune overactivity.

Who could benefit from this research

Good fit: Ideal candidates would be people with autoimmune disease or known STAT1 or STAT3 gain‑of‑function mutations, or patients with immune disorders referred by clinicians.

Not a fit: People whose conditions are unrelated to STAT1/STAT3 signaling or who cannot travel to the research site are unlikely to benefit directly from participating.

Why it matters

Potential benefit: If successful, the findings could point to new targets for drugs that reduce harmful STAT1/STAT3 overactivity and lessen autoimmune disease and infection risk.

How similar studies have performed: Genetic and clinical research has already linked STAT1/STAT3 mutations to immune disease, but applying high‑resolution structural methods to persistent STAT activation is relatively new.
