Abstract

After the first attachment of virus to the cell surface through a primary receptor, efficient entry of virus requires the presence of a coreceptor. For adeno-associated virus type 2 (AAV2) infection, heparan sulfate proteoglycan is supposed as the primary receptor, and αvβ5 integrin and FGFR1 are reported to act as coreceptors. In this study, we were able to demonstrate that hepatocyte growth factor receptor, c-Met, is also a coreceptor for AAV2 infection. AAV2-mediated transgene analyses revealed that c-Met expression significantly up-regulated transgene expression without increasing AAV2 cell binding. Moreover, a viral overlay assay elucidated the physical interaction between AAV2 and the β subunit of c-Met. These data suggest that c-Met plays the role of coreceptor for AAV2 infection by facilitating AAV2 internalization into the cytoplasm.

  • The early steps of AAV infection involve attachment to a variety of cell surface receptors such as HSPG, FGFR, αvβ5 integrin, and hepatocyte growth factor receptor (c-Met), followed by clathrin-dependent endocytosis.

    “The early steps of AAV infection involve attachment to a variety of cell surface receptors such as HSPG, FGFR, αvβ5 integrin, and hepatocyte growth factor receptor (c-Met) (Fig. 8I) (9, 25, 31, 39, 40), followed by clathrin-dependent endocytosis (Fig.8II).”

    The opening summary identifies HSPG as the primary attachment receptor and FGFR1, αvβ5 integrin, and c-Met as AAV2 coreceptors. The Discussion also reports AAV2 internalization from clathrin-coated pits. However, the Results say c-Met did not increase AAV2 cell attachment, so describing c-Met as an attachment receptor is not supported. (LLM, conf=0.88)

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.
