Figure 7From: Cigarette smoke-promoted acquisition of bacterial pathogens in the upper respiratory tract leads to enhanced inflammation in mice Influx of inflammatory cells in the lung. Mice were exposed to CS or air for 3 months and intranasally inoculated with NTHi or S. pneumoniae (S.p.). Numbers of total immune cells (A), macrophages (B) and neutrophils (C) were determined in BAL fluids 24 hours (NTHi) and 4 days (S.p.) postinoculation. Bars indicate significant differences of *p < 0.05 and **p < 0.01, n ≥ 5 per group.Back to article page
