Abstract

Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are highly stable man-made chemicals. They have recently garnered significant attention due to their ubiquitous presence in the environment and deleterious effects on human health including cardiovascular diseases (CVDs). Thrombosis due to platelet activation is a major aspect in CVDs. However, the direct effect and underlying mechanism of PFAS on the platelets remains elusive. Here, we observed that PFAS engagement with the extracellular domain of platelet GPIbα, transduced GPIbα-driven inward signals, resulting in intracellular calcium mobilization, activation of Akt and αⅡbβ3 integrin, culminating in platelet aggregation and procoagulant platelet formation. PFAS pretreatment enhanced GPIb-mediated platelet spreading and thrombus formation under high shear conditions. PFAS-induced platelet activation was markedly decreased in Gpibα-deficient mice. PFAS-primed platelets drove neutrophil extracellular traps formation through GPIbα-dependent pathway. Further, PFAS-exposed mice showed heightened risk of thrombus growth and ischemic stroke. Our findings provide experimental evidence for the causal links between PFAS exposure and thrombotic CVDs. Blockade of GPIbα and the downstream pathways could be an instrumental strategy against PFAS-induced platelet activation and thrombosis.

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.
