IL9IL9R gene expression and numbers of IL-9+ cells are increased in CRSwNP compared to controls. a IL9 and b IL9R gene expression were significantly (resp. p < .05 and p < .0001) increased in tissue of CRSwNP (n = 40) compared to controls (n = 20). c Significantly (p < .01) increased numbers of IL-9+ cells were observed in tissue of CRSwNP (n = 13) compared to controls (n = 5). Gene expression is expressed as normalized relative quantity (NRQ). d IL-9+ neutrophil (arrow) and IL-9 neutrophil (arrowhead) located near each other in the same patient. Both IL-9+ neutrophils (e, g, i) and IL-9 neutrophils (f, h, j) were observed in patients with CRSwNP. Levels of statistical significance are expressed as *p < .05, **p < .01, ***p < .001 and ****p < .0001
