BACKGROUND: Interleukin-16 (IL-16) has been characterized as a chemoattractant for a variety of CD4+ T cells. Several inflammatory diseases, including allergic disorders, have been reported to correlate with IL-16. We first examined the IL-16 expression of serum and mucosal tissue in patients with allergic rhinitis.
METHODS: Forty-eight patients with a clinical history of house dust mite (HDM) or pollen-sensitive allergic rhinitis were included in this study. Serum IL-16 was analyzed by enzyme-linked immunosorbent assay (ELISA). IL-16 expression of nasal mucosa was detected by immunohistochemistry.
RESULTS: IL-16 levels were elevated in the serum of patients with allergic rhinitis compared with normal controls. In particular, serum IL-16 levels in HDM-sensitive patients were higher than those in pollen-sensitive patients. IL-16 was significantly correlated with eosinophils in the peripheral blood of allergic rhinitis patients. Histologically, IL-16 was expressed in infiltrated lymphocytes and nasal gland cells.
CONCLUSIONS: Our data indicate that one of the sources of elevated serum IL-16 in allergic patients may be gland cells and lymphocytes in allergic nasal mucosa. This IL-16 cytokine may be strongly associated with the developmental mechanism of allergic rhinitis.
