Abstract

Macroautophagy (hereafter referred to as autophagy) can increase or decrease the amount of cell death in response to various stimuli. To test whether autophagy also controls the characteristics associated with dying cells, we studied tumor cell killing by epidermal growth factor receptor-targeted diphtheria toxin (DT-EGF). DT-EGF kills epithelial and glioblastoma tumor cells with similar efficiency but by different mechanisms that depend on whether the cells activate autophagy when treated with the drug. Dying cells in which autophagy is induced selectively release the immune modulator high-mobility group B1 (HMGB1) without causing lysis of the cell membrane and classical necrosis. Conversely, cells that are killed by DT-EGF where autophagy is blocked, activate caspases but retain HMGB1. These data suggest that it may be feasible to manipulate the immunogenicity of dying cells by increasing or decreasing autophagy.

  • In a model of immunogenic cell death, immunization with DNA-damaged Bax−/−Bak−/− cells undergoing non-apoptotic death with massive autophagy was more efficient at cross-priming antigen-specific CD8+ T cells than vaccination with wild-type apoptotic cells.

    “In one model of immunogenic cell death, influenza virus-infected Bax−/−Bak−/− mouse embryonic fibroblasts (which cannot engage apoptosis via the mitochondrial pathway) were induced to undergo non-apoptotic cell death accompanied by massive autophagy 65 and immunization with these DNA-damaged Bax−/−Bak−/− cells was found to be more efficient in facilitating the cross-priming of antigen-specific CD8”

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.
