Abstract

Significance: Mechanotransductive release of ATP from RBCs participates in the regulation of microvascular tone and plays essential roles in vascular physiopathology. The mechanism responsible for the release of ATP, however, is poorly understood. We show for the first time, to our knowledge, that Piezo1, the recently identified mechanically activated cation channel, regulates the mechanotransductive release of ATP from RBCs. In particular, we uncover the link between Piezo1, calcium influx, and ATP release and propose a previously unidentified mechanotransductive pathway that modulates the release of ATP from RBCs. The outcome of this study will allow the development of much needed approaches to regulate the release of ATP from RBCs and thus, impact significantly the fields of red cell research, cellular mechanosensing, and Piezo1 channels.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Shear stress, hypoxia, or pharmacological stimuli such as β-adrenergic receptor stimulation activate signaling cascades leading to release of ATP from RBCs through cystic fibrosis transmembrane conductance regulator or pannexin 1 channels.

    “Shear stress, hypoxia, or pharmacological stimuli, such as β-adrenergic receptor stimulation, have been shown to activate signaling cascades leading to release of ATP through cystic fibrosis transmembrane conductance regulator or pannexin 1 channels (36, 53).”

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.
