ABSTRACT

OBJECTIVE To study the content and distribution characteristics of thymic stromal lymphopoietin (TSLP) in nasal mucosa of murine model of allergic rhinitis.METHODS 6-week-old BALB/c mice were divided into control group and experimental group.Mice of experimental group were sensitized by means of dropping OVA in nasal cavity and intraperitoneal injection of OVA. Meanwhile,mice of control group were dealt with physiological saline instead of OVA.The content of TSLP in nasal mucosa of mice was tested by means of real-time PCR and its distribution was detected by means of immunohistochemistry staining.RESULTS The content of TSLP was obviously higher in nasal mucosa of experimental group than that of control group.It was distributed mainly in lamina propria and on the surface of epithelium.CONCLUSION TSLP may play an important role in allergic rhinitis of the mice.
