Identification and immunolocalization of the innate immune receptor CD14 in hypertrophic adenoids and tonsils.

The purpose of this study is to determine the expression of CD14 as a marker of the innate immunity in hypertrophic adenoids and tonsils. Twenty-four pediatric patients (age <12 years) with obstructive adenotonsillar hypertrophy, confirmed by sleep study were included in this study. Intensity and expression of positive CD14 infiltrating cells was assessed by immunohistochemistry in specific histologic areas.
