Activation of the Raf-MEK-ERK pathway is required for neutrophil extracellular trap formation
Abstract
The signaling mechanisms leading to the formation of neutrophil extracellular traps (NETs), relevant in infections, sepsis and autoimmune diseases, are poorly understood. Neutrophils are not amenable to studies with conventional genetic techniques. Using a new chemical genetic analysis we show that the Raf-MEK-ERK pathway is involved in NET formation through activation of NADPH oxidase and upregulation of antiapoptotic proteins. We identify potential targets for drugs addressing NET-associated diseases.

NETotic cell death has been suggested to result from a signaling pathway involving RAF1, MAP2Ks, and ERK2, culminating with NADPH oxidase activation and ROS generation.
“NETotic cell death has been suggested to result from a signaling pathway that involves Raf-1 proto-oncogene, serine/threonine kinase (RAF1), mitogen-activated protein kinase kinases (MAP2Ks), and ERK2, culminating with NADPH oxidase activation and consequent ROS generation [736, 738, 739].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
