Adjuvant alum regulates the eIF2a‐GATA3 axis in CD4+ T cells to influence allergen immunotherapy

Allergen-specific immunotherapy (AIT) is an aetiology-targeting therapy for allergic diseases. The therapeutic mechanism of AIT is not fully understood yet. Endoplasmic reticulum stress is associated with the pathogenesis of allergic disorders. This study aims to elucidate the effects of AIT on suppressing allergic response through regulating endoplasmic reticulum stress. In this study, patients with perennial allergic rhinitis were recruited. AIT was conducted for the patients. An allergic rhinitis (AR) mouse model was established with mite extracts as allergens. We found that AIT modulated the endoplasmic reticulum stress status in peripheral CD4
