Shedding microvesicles: artefacts no more

Cocucci, Emanuele, Racchetti, Gabriella, Meldolesi, Jacopo·2009·Trends in Cell Biology

Abstract

The small vesicles shed from the surface of many cells upon stimulation, considered for a long time to be artefacts, are now recognized as specific structures that are distinct from the exosomes released upon exocytosis of multivesicular bodies. Recent reports indicate that shedding vesicles participate in important biological processes, such as the surface-membrane traffic and the horizontal transfer of protein and RNAs among neighboring cells, which are necessary for the rapid phenotype adjustments in a variety of conditions. In addition, shedding vesicles have important physiological and pathological roles: in coagulation, by mediating the coordinate contribution of platelets, macrophages and neutrophils; in inflammatory diseases, via the release of cytokines; and in tumor progression, facilitating the spreading and release of cancer cells to generate metastases.

Claims other papers make about this one

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

  • Microvesicles arise through direct outward budding and fission of the plasma membrane.

    “The mode of biogenesis of exosomes is distinct from vesicles that arise through direct outward budding and fission of the plasma membrane (Figure 4). To distinguish these vesicles by their mode of biogenesis, the latter class of vesicles is frequently referred to as microvesicles [59].”
  • Extracellular vesicles can transfer RNAs such as non-coding RNAs from one cell to another and thereby contribute to inter-cellular communication.

    “Recent studies have confirmed that EV can transfer RNAs such as ncRNAs from one cell to another and thereby contribute to important roles in inter-cellular communication (3–9).”

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.
