Abstract

Objectives Platelets, specialized adhesive cells, play key roles in normal and pathological hemostasis through their ability to rapidly adhere to subendothelial matrix proteins (adhesion) and to other activated platelets (aggregation), functions which are inhibited by nitric oxide (NO). Platelets have been reported to be regulated not only by exogenous endothelium-derived NO, but also by two isoforms of NO synthase, endothelial (eNOS) and inducible (iNOS), endogenously expressed in platelets. however, data concerning expression, regulation and function of eNOS AND iNOS in platelets remain controversial.Methods and results Using important positive (endothelial cells, stimulated macrophages) and negative (eNOS/iNOS knock-out mouse) controls, as well as human platelets highly purified by a newly developed protocol, we now demonstrate that human and mouse platelets do not contain eNOS/iNOS proteins or mRNA. NOS substrate (L-arginine), NOS inhibitors (L-NAME, L-NMMA), and eNOS/iNOS deficiency did not produce detectable functional effects on human and mouse platelets. von Willebrand factor (VWF)/ristocetin treatment of platelets increased cGMP by NO-independent activation of soluble guanylyl cyclase (sGC) which correlated with Src kinase-dependent phosphorylation of sGC beta(1)-subunit-Tyr(192).Conclusions Human and mouse platelets do not express eNOS/iNOS. VWF/ristocetin-mediated activation of the sGC/cGMP signaling pathway may contribute to feedback platelet inhibition.

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.
