  • Ageing compromises both the primary and secondary RIG-I signalling pathways that control expression of many type I interferon genes.

    “ageing compromises both the primary and secondary RIG-I signaling pathways that control expression of many type I IFN genes115.”

    From SARS-CoV-2, COVID-19 and the aging immune system (2021) · cites this paper as [115]

  • This RIG-I compromise is associated with reduced type I interferon production in people over 65, impairing their antiviral responses such as to influenza A virus.

    “This is associated with reduced production of type I IFNs in those >65, impairing their anti-viral responses, like to respiratory influenza A virus115.”

    From SARS-CoV-2, COVID-19 and the aging immune system (2021) · cites this paper as [115]

  • Monocytes from older adults show impaired primary and secondary RIG-I signalling, caused by lower levels of the adaptor protein TRAF3 and the transcription factor IRF8, respectively.

    “there is an impairment of primary and secondary RIG-I signalling in monocytes from older adults, due to decreased abundance of the adaptor protein tumour necrosis factor receptor-associated factor 3 (TRAF3) and IFN regulatory transcription factor (IRF8) respectively (138).”

    From The impact of ageing on monocytes and macrophages (2021) · cites this paper as [138]

  • The reduced type I interferon production is proposed as one reason older adults are more vulnerable to respiratory infections, since type I interferon is required for infection clearance.

    “is thought to be one of the reasons that older people are more susceptible to respiratory infections, as type I interferon is necessary to clear infection (138).”

    From The impact of ageing on monocytes and macrophages (2021) · cites this paper as [138]

  • This impairment leads to decreased production of type I interferon.

    “This in turn results in reduced type I IFN production”

    From The impact of ageing on monocytes and macrophages (2021) · cites this paper as [138]

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.
