Fig. 2. Immunostained confocal microscopy images confirm the suppression of LPS-mediated NETosis by SP-D.

Fig. 2

ab Neutrophils were activated for 2 h by LPS (a) or ionomycin (b) with or without SP-D at two calcium concentrations and imaged after immunostaining for myeloperoxidase (MPO; green) and staining with DAPI for DNA (blue). MPO co-localized to NET-DNA upon stimulating neutrophils with LPS or ionomycin. a Pre-incubation of the indicated concentrations of SP-D with LPS showed the suppression of NETs release. b SP-D did not suppress NETosis induced by ionomycin (n = 2, with the whole experiment repeated twice, scale bar, 20 μm).
