Heparan sulfate proteoglycan as a cell-surface endocytosis receptor

Abstract

How various macromolecules are exchanged between cells and how they gain entry into recipient cells are fundamental questions in cell biology with important implications e.g. non-viral drug delivery, infectious disease, metabolic disorders, and cancer. The role of heparan sulfate proteoglycan (HSPG) as a cell-surface receptor of diverse macromolecular cargo has recently been manifested. Exosomes, cell penetrating peptides, polycation–nucleic acid complexes, viruses, lipoproteins, growth factors and morphogens among other ligands enter cells through HSPG-mediated endocytosis. Key questions that partially have been unraveled over recent years include the respective roles of HSPG core protein and HS chain structure specificity for macromolecular cargo endocytosis, the down-stream intracellular signaling events involved in HSPG-dependent membrane invagination and vesicle formation, and the biological significance of the HSPG transport pathway. Here, we discuss the intriguing role of HSPGs as a major entry pathway of macromolecules in mammalian cells with emphasis on recent in vitro and in vivo data that provide compelling evidence of HSPG as an autonomous endocytosis receptor. • Heparan sulfate proteoglycan (HSPG) is a receptor of diverse macromolecular cargo. • HSPG endocytosis is involved in infectious disease, lipid metabolism and cancer. • HSPG represents an interesting target for macromolecular drug delivery. • Recent findings on the intriguing role of HSPG-mediated transport are discussed.

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

  • Extracellular tau can be taken up by neighboring cells, both neurons and glial cells, through various pathways including phagocytosis, macropinocytosis, receptor-mediated uptake, endocytosis, and/or membrane fusion of exosomes.

    “Meanwhile, the extracellular tau can be taken up by neighboring cells, both neurons and glial cells, through various pathways, including phagocytosis [68], macropinocytosis [69], receptor-mediated uptake [67, 70], endocytosis [71], and/or membrane fusion of exosomes [72, 73].”

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.
