3.2 The expression of the leukotriene receptor was stable in all types of adenoid tissues. The expression of glucocorticoid receptor was higher in edematous type.
101 adenoid tissues were obtained from surgical patients. We found that adenoid tissues requiring surgical treatment were mostly of the common type (Fig. 2A), and children with fibrous type tissue were older than the ones with edematous type tissue (Fig. 2B). The results of immunohistochemical staining (Fig. 3A) and Western blot (Fig. 3B) showed that the leukotriene receptors were stable in all three types of adenoid tissues, and glucocorticoid receptors were highly expressed in the edematous type. Additionally, H&E staining showed higher eosinophilic infiltration in the edematous type. We found that eosinophil count was higher in the edematous type than in the common type (Fig. 4A).
