Abstract

The suppression of the immune system by overexposure to ultraviolet (UV) radiation has been implicated in the initiation and progression of photocarcinogenesis. Numerous changes occur in the skin on UVB exposure, including the generation of inflammatory mediators, DNA damage, epigenetic modifications, and migration and functional alterations in the antigen‐presenting dendritic cells. Although each of these alterations can elicit a cascade of events that have the potential to modulate immune sensitivity alone, there is emerging evidence that there is considerable crosstalk between these cascades. The development of an understanding of UV‐induced changes in the skin that culminate in UV‐induced immunosuppression, which has been implicated in the risk of nonmelanoma skin cancer, as a network of events has implications for the development of more effective chemopreventive strategies. In the current review article, we discuss the evidence of interactions between the various molecular targets and signaling mechanisms associated with UV‐induced immunosuppression.

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

  • The DNA damage response is a potent activator of inflammatory responses.

    “The DDR is a potent activator of inflammatory responses.”

    From The central role of DNA damage in the ageing process (2021) · cites this paper as [90]

  • Rapid repair of dipyrimidine photoproducts is expected to greatly minimize UV-induced immune suppression because the duration of unrepaired CPDs in genomic DNA is a primary signal for initiating this suppression.

    “This rapid repair of dipyrimidine photoproducts is also expected to greatly minimize UV-induced immune suppression since one of the primary signals for initiating this suppression is the duration of unrepaired CPDs in genomic DNAs25,37–39.”
  • Solar UV exposure acts as a systemic immunosuppressant, compromising an individual's immune response with mechanistic implications for photocarcinogenesis.

    “Contributing to the adverse effects of solar UV exposure is its known action as a systemic immunosuppressant, compromising an individual’s immune response with mechanistic implications for photocarcinogenesis (13).”

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.
