Study links severe COVID cases to pre-existing anti-interferon immunity
Key Takeaways
- A Cell study examined why key antiviral defenses failed in some severe COVID patients.
- Researchers found pre-existing B-cell populations that targeted type I interferons.
- These patients produced autoantibodies that neutralized an early antiviral signal.
- The results suggest hidden autoimmunity may shape vulnerability to severe viral disease.
