Eosinophil response in the lung observed by cell phenotyping.

<p>To understand the eosinophil cell phenotypes in the lung, cells from the lung (n = 6) were isolated and stained with surface markers. Eosinophil (CD11b⁺SiglecF⁺) in CD45⁺CD11c^– total cells were analyzed (A, B and C, *P < 0.05, **P < 0.01). The data shown are representative of three independent experiment. FI-RSV immunized mice showed significantly high levels of eosinophil and macrophage response compared to naïve or naïve challenge control mice. In contrast, V1 and V5 VLPs immunized mice showed lower eosinophil responses compared to FI-RSV and naïve challenge control. Compared to V1 VLPs, V5 VLPs showed lower eosinophil responses. The data shown are representative of three independent experiments.
