Increased local IgE production induced by common aeroallergens and phenotypic alteration of mast cells in Chinese eosinophilic, but not non‐eosinophilic, chronic rhinosinusitis with nasal polyps

Abstract

The local IgE induced by common aeroallergens may mediate mast cell activation and contribute to subsequent eosinophilic inflammation in Chinese CRSwNP. This study offers a rationale for considering intervention strategies designed to target 'local allergy' in eosinophilic CRSwNP.
