Immune Imbalance in Nasal Polyps of Caucasian Chronic Rhinosinusitis Patients Is Associated with a Downregulation of E-Selectin
Figure 4
(a): Expression and localization of E-selectin in inferior turbinates and nasal polyps of chronic rhinosinusitis patients (). Immunohistochemical staining was performed on frozen tissue sections of inferior turbinate (left) and nasal polyp (right). We were able to detect E-selectin positive cells in the endothelium of inferior turbinates and nasal polyps. E-selectin was expressed at high level in the inferior turbinates, whereas in nasal polyps E-selectin was infrequently expressed and always at a low level. (b) Expression and localization of P-selectin in inferior turbinates and nasal polyps of chronic rhinosinusitis patients (). Immunohistochemical staining was performed on frozen tissue sections of inferior turbinate (left) and nasal polyp (right). P-selectin was detected in the endothelium of inferior turbinates and nasal polyps. P-selectin was always expressed at high levels in both inferior turbinates and nasal polyps.
