After quantification, Fig. 1b shows that Congo red-positive cells were significantly more common in the eosinophil-dominant CRSwNP patients (p < 0.01), while CD138-positive cells were more highly expressed in the plasma cell-dominant CRSwNP patients than in the eosinophil-dominant CRSwNP patients (Fig. 1c, p < 0.01). The gene discussed is SDC1; the disease is chronic rhinosinusitis with nasal polyps.
