Natural killers shed attachments to kill again.
Felce JH., Dustin ML.
Natural killer cells target antibody-bound cells following engagement of the Fc receptor CD16. Srpan et al. (2018. J. Cell Biol. https://doi.org/10.1083/jcb.201712085) reveal that activation-induced shedding of CD16 leads to more motile behavior, allowing more targets to be engaged and killed in a given time.
