Effects of Stat3-EVA overexpression on leukocyte counts in BAL fluid from IgG IC-injured lungs. Leukocytes were quantitated in BAL fluids 4, 8, and 24 h after onset of IgG IC-induced lung injury in mice treated with either Ad-GFP or Ad-Stat3-EVA. Leukocytes were also quantitated in BAL fluids from control mice that received αBSA intratracheally together with either Ad-STAT3-EVA or Ad-GFP, but in the absence of intravenously administered BSA. Total numbers of leukocytes (A), neutrophils (B), and macrophages/lymphocytes (C) are shown. Results are expressed as means ± se; n = 3 for control and n = 5 for other time points. *P < 0.05, **P < 0.01.
