Abstract

Poliovirus replication is limited to a few organs, including the brain and spinal cord. This restricted tropism may be a consequence of organ-specific differences in translation initiation by the poliovirus internal ribosome entry site (IRES). A C-to-U mutation at base 472 in the IRES of the Sabin type 3 poliovirus vaccine strain, known to attenuate neurovirulence, may further restrict tropism by eliminating viral replication in the CNS. To determine the relationship between IRES-mediated translation and poliovirus tropism, recombinant human adenoviruses were used to express bicistronic mRNAs in murine organs. The IRESs of poliovirus, the cardiotropic coxsackievirus B3 (CVB3), and the hepatotropic hepatitis C virus (HCV) mediate translation in many organs, including those that do not support viral replication. A translation defect associated with the Sabin type 3 IRES was observed in all organs examined. Poliovirus type 1 and recombinant polioviruses dependent on the IRES of CVB3 or HCV replicate in the CNS of mice and cause paralysis. Although the type 3 Sabin strain is an effective vaccine, polioviruses with a U at base 472 of the IRES cause paralysis in newborn mice. Tropism of wild-type and vaccine strains of poliovirus is therefore determined after internal ribosome entry.

  • DomV forms part of the internal ribosome entry site (IRES), and destabilizing this structure is thought to reduce the efficiency of translation initiation.

    “DomV forms part of the internal ribosome entry site (IRES), and it is thought that destabilizing this structure reduces the efficiency of translation initiation (Kauder and Racaniello, 2004, Macadam et al., 1994, Svitkin et al., 1990).”

    From Engineering the Live-Attenuated Polio Vaccine to Prevent Reversion to Virulence (2020) · cites this paper as Kauder and Racaniello, 2004

    The Introduction identifies the poliovirus IRES as a site of translation initiation, and the section on vaccine-strain IRES mutations reports that C472U decreases IRES-dependent translation. Our copy does not identify DomV or say that destabilizing its structure causes that decrease, so the structural mechanism is not supported by this source. (LLM, conf=0.85)

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.
