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).
