Abstract

The cuprizone mouse model allows the investigation of the complex molecular mechanisms behind nonautoimmune-mediated demyelination and spontaneous remyelination. While it is generally accepted that oligodendrocytes are specifically vulnerable to cuprizone intoxication due to their high metabolic demands, a comprehensive overview of the etiology of cuprizone-induced pathology is still missing to date. In this review we extensively describe the physico-chemical mode of action of cuprizone and discuss the molecular and enzymatic mechanisms by which cuprizone induces metabolic stress, oligodendrocyte apoptosis, myelin degeneration and eventually axonal and neuronal pathology. In addition, we describe the dual effector function of the immune system which tightly controls demyelination by effective induction of oligodendrocyte apoptosis, but in contrast also paves the way for fast and efficient remyelination by the secretion of neurotrophic factors and the clearance of cellular and myelinic debris. Finally, we discuss the many clinical symptoms that can be observed following cuprizone treatment, and how these strengthened the cuprizone model as a useful tool to study human multiple sclerosis, schizophrenia and epilepsy.

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

  • Cuprizone-induced apoptosis precedes massive demyelination, indicating that oligodendrocyte degeneration is the main cause, as opposed to a secondary immune response.

    “Importantly this apoptosis precedes the massive demyelination caused by cuprizone administration [18], indicating that oligodendrocyte degeneration is the main cause, as opposed to a secondary immune response.”

  • The involvement of brain resident neuroinflammatory cells such as microglia and astrocytes is believed to be responsible for the massive demyelination occurring at 4 weeks of cuprizone exposure.

    “In addition to the direct effect of cuprizone on oligodendrocytes, the involvement of the brain’s resident neuroinflammatory cells such as microglia and astrocyes is also believed to be responsible for the massive demyelination occurring at 4 weeks time point of cuprizone exposure [18].”

  • Cuprizone selectively affects oligodendrocytes.

    “Nevertheless, a consensus seems to be that cuprizone selectively affects oligodendrocytes.”

    From Strain differences in cuprizone induced demyelination (2017) · cites this paper as [18]

  • Astrocytes and microglia collaborate through the release of cytokines, chemokines, and other factors to drive demyelination; preventing the release of specific cytokines or chemokines, restricting astrocyte reactivity, or ablating microglia all reduce cuprizone-induced demyelination.

    “Astrocytes and microglia collaborate through the release of cytokines, chemokines, and other, yet to be identified factors, to drive demyelination [79, 107], preventing the release of specific cytokines or chemokines, restricting astrocyte reactivity, or ablating microglia all reduce cuprizone-induced demyelination [107, 181, 189, 243].”
  • The cuprizone model is based on oral ingestion of the copper chelator cuprizone, causing metabolic oligodendrocyte injury.

    “The cuprizone model is based on oral ingestion of the copper chelator cuprizone, causing metabolic oligodendrocyte injury.”

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.
