Increased numbers of myeloid DCs, plasmacytoid DCs, and their activated subsets were found in both types of CRSwNP, but only myeloid DCs and plasmacytoid DCs from eosinophilic CRSwNP demonstrated an up-regulation of OX40 ligand (OX40L) and programmed death ligand 1(PD-L1) expression. Lesional DCs from both types of CRSwNP produced enhanced levels of IL-12, IL-6, and transforming growth factor-\u03b2, and induced increased Th1 and Th17 responses; in contrast, only DCs from eosinophilic CRSwNP induced obviously enhanced Th2 responses, when cocultured with naive CD4+ T cells.
