Research Abstract

Nasopharynx and nasal mucosa are located at the forefront of the host defense against foreign pathogens, which plays an important role in acquired immunity and innate immunity. To elucidate the immune system of allergy infection, we analyzed the mechanism of epithelial barrier function and antigen presentation in the nasal epithelium of human nasopharyngeal epithelium.
