Ovalbumin induces natural killer cells to secrete Th2 cytokines IL-5 and IL-13 in a mouse model of asthma

Asthma is a chronic lung disease characterized by an imbalance of T-helper (Th)1/Th2 cells and their cytokine profiles. Natural killer (NK) cells constitute a considerable subset of the lymphocyte population in the lungs, and provide protection against respiratory infection by fungi, bacteria and vi...

description Asthma is a chronic lung disease characterized by an imbalance of T-helper (Th)1/Th2 cells and their cytokine profiles. Natural killer (NK) cells constitute a considerable subset of the lymphocyte population in the lungs, and provide protection against respiratory infection by fungi, bacteria and viruses. However, the mechanism by which NK cells are involved in asthma remains to be fully elucidated. The present study analyzed the dynamic changes of NK cells and their subsets during the development of the ovalbumin (OVA)-induced allergic airway response. Lung tissues were histologically examined for cell infiltration and mucus hypersecretion. The number, activity and cytokine-secreting ability of NK cells was determined by flow cytometry. The results showed that the percentage of NK cells in the lung was decreased following OVA sensitization and challenge. However, NK cells exhibited enhanced activity and secreted more Th2 cytokines (IL-5 and IL-13) following OVA challenge. Furthermore, the proportion of CD11b(−) NK subsets increased with the development of asthma, and CD11b(−) CD27(−) NK cells were the primary NK subset producing Th2 cytokines. These findings suggest that, although NK cells are not the crucial type of lymphocytes involved in asthma, OVA induces NK cells to secrete Th2 cytokines that may be involved in the pathogenesis of asthma.
