Abstract

Conventional cancer treatments rely on radiotherapy and chemotherapy. Such treatments supposedly mediate their effects via the direct elimination of tumor cells. Here we show that the success of some protocols for anticancer therapy depends on innate and adaptive antitumor immune responses. We describe in both mice and humans a previously unrecognized pathway for the activation of tumor antigen-specific T-cell immunity that involves secretion of the high-mobility-group box 1 (HMGB1) alarmin protein by dying tumor cells and the action of HMGB1 on Toll-like receptor 4 (TLR4) expressed by dendritic cells (DCs). During chemotherapy or radiotherapy, DCs require signaling through TLR4 and its adaptor MyD88 for efficient processing and cross-presentation of antigen from dying tumor cells. Patients with breast cancer who carry a TLR4 loss-of-function allele relapse more quickly after radiotherapy and chemotherapy than those carrying the normal TLR4 allele. These results delineate a clinically relevant immunoadjuvant pathway triggered by tumor cell death.

  • Extracellular HMGB1 is required for the immunogenicity of ICD and binds to TLR-4 on DC to mediate cross-presentation efficiency.

    “Extracellular HMGB1 is required for the immunogenicity of ICD. It binds to the Toll-like receptor 4 (TLR-4) on the surface of DC and mediates cross-presentation efficiency [39].”
  • Six DAMPs have been mechanistically linked to perception of RCD as immunogenic: CALR, ATP, HMGB1, type I IFN, cancer cell-derived nucleic acids, and ANXA1.

    “So far, six DAMPs have been mechanistically linked to the perception of RCD as immunogenic: (1) calreticulin (CALR) [865, 866], (2) ATP [867–869], (3) high-mobility group box 1 (HMGB1) [870–872], (4) type I IFN [854, 873, 874], (5) cancer cell-derived nucleic acids [864, 875], and (6) annexin A1 (ANXA1) [876].”
  • HMGB1-TLR4 ligation on DCs promotes antigen processing and cross-presentation but does not induce DC maturation, which is mainly stimulated by RAGE.

    “In particular, the ligation of HGMB1 to TLR4 on DCs promotes antigen processing and cross-presentation, yet does not induce DC maturation, which is mainly stimulated by RAGE [870, 916].”
  • RCD is not perceived as immunogenic when cancer cells lack HMGB1 or ANXA1, or host lacks TLR4 or FPR1.

    “In line with these observations, RCD is not perceived as immunogenic when cancer cells are depleted of HMGB1 or ANXA1, as well as when the host lacks TLR4 or FPR1 [870, 876].”
  • During radiotherapy or chemotherapy, immune responses may be biased toward tumor antigens rather than normal self-antigens.

    “Consequently, during radiotherapy or chemotherapy in which the tumor cells are induced to die, immune responses may be biased towards a response against the tumor antigens rather than normal self-antigens, to which the immune system has been tolerized 7,27,28.”

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.
