E/LPS lung injury alters inflammatory cell recruitment in response to RSV. BAL was performed on PBS + Mock–, E/LPS + Mock–, PBS + RSV–, and E/LPS + RSV–treated mice at Days 0, 1, 4, 7, 10, and 14 after RSV infection. (A) Total cell counts and differential analysis for (B) macrophages, (C) neutrophils, and (D) lymphocytes were performed on isolated BAL cells. E/LPS-treated mice show increased total BAL cells, macrophages, neutrophils, and lymphocytes in response to RSV when compared with PBS-treated mice; n = 6 mice per group; data reported as mean (±SEM); †P < 0.05, different from PBS + mock–infected group; #P < 0.05, different from E/LPS + mock–infected group; *P < 0.05, different from PBS group.
