Disease-Specific T-Helper Cell Polarizing Function of Lesional Dendritic Cells in Different Types of Chronic Rhinosinusitis with Nasal Polyps

Abstract

Distinct subsets of lesional DCs were found in eosinophilic and noneosinophilic CRSwNP, where OX40L/PD-L1(+) lesional DCs in eosinophilic CRSwNP could prime Th2 cells, whereas the low OX40L/PD-L1-expressing lesional DCs in noneosinophilic CRSwNP primarily induced Th1/Th17 cells.
