Abstract

Significance: Exosome-mediated intercellular transfer of proteins and nucleic acids has attracted considerable attention as exosomes may promote the development of cancer and other pathological conditions; however, the mechanism of exosome uptake by target cells and how this may be inhibited remain as important questions. We provide evidence that heparan sulfate proteoglycans (HSPGs) function as receptors of cancer cell-derived exosomes. Importantly, our data indicate that the HSPG-dependent uptake route is highly relevant for the biological activity of exosomes, and thus a potential target for inhibition of exosome-mediated tumor development. Given that several viruses have previously been shown to enter cells through HSPGs, our data implicate HSPG as a convergence point during cellular uptake of endogenous vesicles and virus particles.

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.
