Abstract

Among numerous established human hepatoma cell lines, none has been shown susceptible to hepatitis B virus (HBV) infection. We describe here a cell line, called HepaRG, which exhibits hepatocyte-like morphology, expresses specific hepatocyte functions, and supports HBV infection as well as primary cultures of normal human hepatocytes. Differentiation and infectability are maintained only when these cells are cultured in the presence of corticoids and dimethyl sulfoxide. The specificity of this HBV infection model was ascertained by both the neutralization capacity of HBV-envelope protein-specific antibodies and the competition with an envelope-derived peptide. HepaRG cells therefore represent a tool for deciphering the mechanism of HBV entry. Moreover, their close resemblance to normal human hepatocytes makes them suitable for many applications including drug metabolism studies.

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.
