Cell Death Mechanisms and Their Implications in Toxicology

Orrenius, Sten, Nicotera, Pierluigi, Zhivotovsky, Boris·2011·Toxicological Sciences

Abstract

Necrotic cell death was long regarded as the ultimate consequence of chemical toxicity and was thought to result from simple cell failure because of toxic interference with vital cell functions. Introduction of the novel concept of programmed cell death (PCD), or apoptosis, has changed this view dramatically. This development has been further stimulated by the characterization of several other genetically PCD modalities, such as autophagy and pyroptosis. Like apoptosis, these modes of cell death are governed by complex signaling networks, containing "switches" responsible for cross talk between them. Recruitment or repression of these cell death signaling networks by foreign chemicals can lead to acute as well as chronic toxicity. In many instances, such effects of toxicants are mediated by disruption/modulation of cellular Ca(2+) homeostasis or increased generation of reactive oxygen species in the mitochondria or other intracellular compartments. Caspases, calpains, lysosomal proteases, and endonucleases are the main executioners of cell death, and they often co-operate during the execution stage of apoptosis. Finally, dead or dying cells are recognized and engulfed by phagocytes to prevent inflammation and associated tissue damage. Defective macrophage engulfment and degradation of cell corpses may also result from toxicity and can contribute to both the inflammatory response and dysregulation of tissue homeostasis. Hence, the cell death and phagocytosis regulatory networks offer a multitude of targets for toxic chemicals.

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.
