How Gut Bacteria and Inflammation Control Daily Patterns of Gout Attacks

AI simplified

Abstract

The may influence the circadian rhythmicity of gout flares by modulating serum uric acid levels.

  • The NF-κB signaling pathway is a central inflammatory process in gout and shows strong circadian patterns.
  • Circadian clock genes, particularly REV-ERBα, regulate the NF-κB pathway in relation to gout inflammation.
  • Circadian variations in serum uric acid levels may be induced by the gut microbiota's influence on REV-ERBα expression.
  • The interaction of the gut microbiota, REV-ERBα, and NF-κB signaling could explain the timing of gout flare occurrences.
  • Chronobiology-based therapies targeting this gut microbiota/REV-ERBα/NF-κB axis may offer new treatment strategies for gout.
