Abstract
BACKGROUND: TNF-TNFR2 signaling has been indicated to be involved in CD4+ T lymphocyte differentiation. However, its role in allergic airway inflammation is not well understood. OBJECTIVES: The aim of this study was to investigate the role of TNF-TNFR2 signaling in allergic airway inflammation. METHODS AND RESULTS: In this study, we used an allergen-induced asthma model to show that TNF-TNFR2 signaling alleviated allergic airway inflammation by reducing the airway infiltration of eosinophils and neutrophils. Activated TNF-TNFR2 signaling decreased the expression of Th2 and Th17 cytokines in serum and bronchoalveolar lavage fluid. Furthermore, TNF-TNFR2 signaling inhibited Th2 and Th17 polarization but promoted Th1 and CD4+CD25+ T cell differentiation in vivo. CONCLUSIONS: Our study indicates that TNF-TNFR2 signaling alleviates allergic airway inflammation through inhibition of Th2 and Th17 cell differentiation.
