Expression of TLR4 in macrophages from induced sputum. Macrophages were gated within the CD45+ cells and identified as CD14+CD66b. a Example of TLR4 expression by induced sputum macrophages in asthmatic subjects with high total serum IgE (dotted histogram) versus asthmatic patients with normal IgE level (grey line histogram). b Expression of TLR4 in macrophages of induced sputum in asthmatic subjects with normal versus high level total serum IgE (values are mean percentage and 95 % confidence intervals)
