Fig. 5.
Neutrophil apoptosis induced by various concentrations of IAV alone or IAV in combination with 250 μg/mL of E coli.Neutrophils were incubated for 1 hour at 37°C with the indicated concentrations of IAV alone (top panel) or IAV in combination with 250 μg/mL (or 1.2 × 109 particles/mL; or 240 bacteria/neutrophil) of E coli (bottom panel). (*)Indicates where IAV alone caused significantly greater apoptosis than control buffer. (**)Indicates where the combination of E coli and IAV caused significantly greater apoptosis than IAV or E colialone.
