Abstract

Significance: The last decade has seen a rapid expansion of interest in extracellular vesicles (EVs), proposed to mediate cell–cell communication in patho/physiological conditions. Although heterogeneity of EVs has become obvious, as highlighted recently by the International Society for Extracellular Vesicles, the field is lacking specific tools to distinguish EVs of different intracellular origins, and thus probably different functions. Here, thanks to a comprehensive comparison of different types of EVs isolated from a single cell type, we define proteins generically present in EVs, small EV-specific and -excluded ones, and a few specific of endosome-derived exosomes or nonexosomal small EVs. This work will allow proper evaluation of the molecular mechanisms of biogenesis and secretion and the respective functions of subtypes of EVs.

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

  • The results imply that CD81-containing EVs, multivesicular bodies, and CD9-positive small EVs derived from the plasma membrane could accumulate in the DNs.

    “The results imply that CD81-containing EVs, multivesicular bodies, and CD9-positive small EVs derived from the plasma membrane could accumulate in the DNs [39, 44].”

    From Abnormal accumulation of extracellular vesicles in hippocampal dystrophic axons and regulation by the primary cilia in Alzheimer's disease (2023) · cites this paper as [39]

    The Results (p. 6) suggest that CD9-only small EVs probably form at the plasma membrane or early endocytic locations, and the Discussion (p. 8) links tetraspanin-bearing small EVs to the endosomal pathway. The paper does not establish that CD81-containing EVs specifically originate in multivesicular bodies or that any of these structures accumulate in DNs. (LLM, conf=0.83)

  • Most mitochondrial components have been reported to fractionate in larger EVs by proteomic analysis.

    “Most mitochondrial components have been reported to fractionate in larger EVs by proteomic analysis [395].”

    From Mechanisms, efficacy, and future perspectives of cellular-based therapies for liver fibrosis/cirrhosis: focusing on mesenchymal stromal cells (2025) · cites this paper as [395]

    The Results (p. 4) report enrichment of mitochondrial proteins in the F5-10K fraction, and the Discussion (p. 8) places mitofilin and possibly other mitochondrial proteins in large and medium-sized EVs rather than small EVs. The paper does not establish that most mitochondrial components fractionate into larger EVs; its analysis concerns EVs from human dendritic cells. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • Heterogeneity of EV fractions was confirmed by probing for different vesicular protein markers.

    “Heterogeneity of these different fractions was confirmed by probing for different vesicular protein markers that are present in all types of EVs and larger vesicle fractions (Flotillin-1) (Kowal et al., 2016), those typically associated with exosomes and absent in 2,000 × g (ALIX and TSG101), and GAPDH found to be enriched in the 2,000 × g and cellular fraction (McNamara et al., 2018).”

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.
