• Selective Autophagy Tunes IRF3 and Type I IFN

  2026-08-12

  Wu and colleagues show that CALCOCO2/NDP52-mediated selective autophagy controls IRF3 stability according to viral burden, while PSMD14 preserves IRF3 by removing K27-linked ubiquitin chains at lysine 313. The work defines a regulatory axis that limits excessive antiviral signaling without eliminating the basal IRF3 required for type I interferon production.
