To the Editor: The nasopharyngeal ep让helium is frequently exposed to various harmful carcinogens. When the nasopharvngeal mucosa is damaged, local inflammation is induced.[1] Chronic inflammation of the nasopharyngeal epithelium may eventually evolve into nasopharyngeal carcinoma (NPC). While the mucus secreted by the nasopharyngeal epithelium forms the body's primitive immune protection barrier as it contains a series of proteins and peptides that can sense, bind, degrade and remove various harmful substances. Lactotransferrin (LTF)[2] and bactericidal/permeability-increasing (BPI) protein family members[3] are an important component of the innate immune protection barrier.
