Neutrophil migration through RSV infected monolayers show increased cell surface expression of CD11B and MPO. Neutrophils that migrated through RSV infected epithelial cells infected for (A) 24 hours or (B) 72 hours showed higher cell surface expression of CD11B and MPO compared to those that migrated through mock-infected epithelial cells. Neutrophils were collected from the apical compartments and the percentage stained for cell surface expression of CD11B (PE) and MPO (APC) were determined by flow cytometry. Neutrophils were gated on initially using a PE positive gate. Using this population the geometric mean fluorescence intensity of PE and APC fluorescence was calculated. Neutrophils from the same donor were compared. Bars show mean ± SEM of n = 4 biological repeats. Statistical significance is shown. For all other comparisons P > 0.05.
