Mouse Lung with Ensnared Bacterium

Caption

This image of a mouse lung, taken with a scanning electron microscope, shows a Klebsiella pneumonia bacterium (pink) snared in a neutrophil extracellular trap (green), a web of chromatin released by neutrophil immune cells to catch and kill pathogens. Papayannopoulos et al. reveal that two enzymes help neutrophils deploy these traps by unraveling the chromatin contained in the cells’ nuclei.
