Key Points

  • This work aims to explore the role of the type 2 inflammation-ALOX15-15(S)-HETE-PPAR-γ axis in chronic rhinosinusitis with nasal polyps.
  • Establishing the ALOX15-15(S)-HETE-PPAR-γ axis
  • Assessing tissue remodeling impairment
  • Evaluating TGF-β1 suppression impact
  • Identified the inflammation-ALOX15-15(S)-HETE-PPAR-γ axis as a key driver
  • Demonstrated impaired tissue remodeling in chronic rhinosinusitis with nasal polyps
  • Highlighted potential therapeutic targets for treatment

Abstract

This work establishes the type 2 inflammation-ALOX15-15(S)-HETE-PPAR-γ axis as a key driver of impaired tissue remodeling in ECRSwNP through TGF-β1 suppression. These findings provide novel mechanistic insights into the inflammation-metabolism-remodeling interplay in CRSwNP and highlight promising therapeutic targets for this refractory condition.
