Abstract

Bifidobacteria are considered one of the most beneficial probiotics and have been widely studied for their effects in preventing and treating specific pathological conditions. The present study explored the antiviral activity of Bifidobacterium adolescentis SPM0212 isolated from healthy Koreans against hepatitis B virus (HBV) and its mechanism of action. To determine the effect of B. adolescentis SPM0212 against HBV, the level of HBV surface antigen (HBsAg) in the culture medium and the levels of viral transcripts in HepG2.2.15 cells were measured by enzyme-linked immunosorbent assay and reverse transcription-quantitative PCR (RT-qPCR), respectively. To clarify the mechanism, we performed RT-qPCR using specific primers for genes encoding Interferon (IFN)-signaling components and IFN-inducible antiviral effectors. The cell extract of B. adolescentis SPM0212 dose-dependently decreased the extracellular HBsAg level by up to 50 %. Its gene expression in HepG2.2.15 cells was also inhibited by 40 %. This extract significantly increased the expression level of myxovirus resistance A, which is an IFN-inducible antiviral effector. Furthermore, the antiviral activity was observed in the fraction of compound(s) with molecular weights under 30 kDa. Thus, the cell extract of B. adolescentis SPM0212 inhibits HBV and its antiviral mechanism is associated with the Mx GTPase pathway.

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

  • In in vitro cell model HepG2.2.15, cell extract of B. adolescentis SPM0212 inhibited HBV, and its antiviral mechanism was associated with the Mx GTPase pathway.

    “Lee et al. [162] reported that in the in vitro cell model HepG2.2.15, containing integrated HBV DNA and secreting hepatitis B virus surface antigen-AgHBs, the cell extract of B. adolescentis SPM0212 inhibited HBV, and its antiviral mechanism was associated with the Mx GTPase pathway.”

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.
