Abstract

Reactive oxygen species (ROS) are key components of postreceptor intracellular signaling pathways; however, the role of ROS in signal initiation is uncertain. We discovered that receptor–ligand interaction caused the generation of hydrogen peroxide (H 2 O 2 ). Using members of the hematopoietin receptor superfamily, as well as EGF receptor, we show that H 2 O 2 is generated by specific receptor–ligand interaction in cells and in cell-free systems. With cognate ligand, the extracellular domain of the receptor was sufficient for H 2 O 2 generation. We also found that production of H 2 O 2 was diminished in a granulocyte–macrophage colony-stimulating factor receptor mutant unable to bind ligand. Exogenously added H 2 O 2 induced signaling in the absence of ligand, whereas catalase and a membrane-bound peroxiredoxin inhibited ligand-dependent signaling. Our results suggest that H 2 O 2 produced by receptor–ligand interaction is involved as a chemical mediator that facilitates cell signaling.

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.
