Expressions of OX40L, PDL1 and ICOSL on activated CD1c⁺ DCs in NP tissues. Representative flow-cytometry pseudocolor density plots, in which gray-pink-blue indicates increasing cell density, showing the percentages of CD86⁺OX40L⁺, CD86⁺PDL1⁺, CD86⁺ICOSL⁺ and IL-17RB⁺OX40L⁺ cells in CD1c⁺ DCs in nasal tissues from healthy controls (n = 16) and polyp tissues from NP patients (n = 30) (a). Quantification of CD86⁺OX40L⁺, CD86⁺PDL1⁺, CD86⁺ICOSL⁺ and IL-17RB⁺OX40L⁺ cells in CD1c⁺ DCs (b). Data are presented as a percentage of the positive cells in CD1c⁺ DCs and mean with SD or median with IQR
