Bacteria can be trapped by neutrophil extracellular traps (NETs) in vitro, but their relevance in vivo is uncertain, in part because NETs are thought to be released by dying neutrophils, thereby eliminating the other antimicrobial functions of these cells. Paul Kubes and his colleagues report in this issue that NET release need not kill neutrophils and that NETosis can by dynamically imaged in vivo.
