Neutrophils contain granules loaded with antimicrobial proteins and are regarded
as impermeable organelles that deliver cargo via membrane fusion. However, during
the formation of neutrophil extracellular traps (NETs), neutrophil elastase (NE)
translocates from the granules to the nucleus via an unknown mechanism that does
not involve membrane fusion and requires reactive oxygen species (ROS). Here, we
show that the ROS triggers the dissociation of NE from a membrane-associated
complex into the cytosol and activates its proteolytic activity in a
myeloperoxidase (MPO)-dependent manner. In the cytosol, NE first binds and
degrades F-actin to arrest actin dynamics and subsequently translocates to the
nucleus. The complex is an example of an oxidative signaling scaffold that
enables ROS and antimicrobial proteins to regulate neutrophil responses.
Furthermore, granules contain protein machinery that transports and delivers
cargo across membranes independently of membrane fusion.
