Neutrophil extracellular trap formation upon influenza virus infection with and without pre-treatment of virus-free condition media. a SYTOX green staining for the extracellular DNA in [1] A/VN/1203/04 (H5N1), [2] A/HK/483/97 (H5N1), [3] A/OK/447/08 (H1N1) and [4] A/HK/415742/09 (H1N1pdm) infected neutrophil at 6 hpi. The A/OK/447/08 (H1N1) infected neutrophil showed the entrenched morphology of the staining represents stretching out of DNA material from the nucleus of neutrophil which is one of the typical indicators of NET formation. b Scanning electron microscopy of [1] mock, [2] A/HK/483/97 (H5N1) [3] A/OK/447/08 (H1N1) infected neutrophils at 6 hpi, scale bar = 50 μm
