IL-15 complex increases NK cells in asthmatic mice. The numbers of NK cells (NKP46⁺, DX5⁺, CD3⁻) were respectively measured in (a) lungs, (b) mediastinal lymph nodes and (c) spleen by flow cytometry. The dissected lungs, mediastinal lymph nodes, and spleen from HDM and HDM IL-15 Cx were crushed, filtered, and then lysed by Red Blood Cell lysis (RBC) for lungs and spleen. The data are represented as mean ± SEM (between 5 and 6 mice per group); * p < 0.05, ** p < 0.01, *** p < 0,001 using parametric t-test. ns = not significant
