Remyelination in the CNS: from biology to therapy

Franklin, Robin J. M., ffrench-Constant, Charles·2008·Nature Reviews Neuroscience

Abstract

Remyelination involves reinvesting demyelinated axons with new myelin sheaths. In stark contrast to the situation that follows loss of neurons or axonal damage, remyelination in the CNS can be a highly effective regenerative process. It is mediated by a population of precursor cells called oligodendrocyte precursor cells (OPCs), which are widely distributed throughout the adult CNS. However, despite its efficiency in experimental models and in some clinical diseases, remyelination is often inadequate in demyelinating diseases such as multiple sclerosis (MS), the most common demyelinating disease and a cause of neurological disability in young adults. The failure of remyelination has profound consequences for the health of axons, the progressive and irreversible loss of which accounts for the progressive nature of these diseases. The mechanisms of remyelination therefore provide critical clues for regeneration biologists that help them to determine why remyelination fails in MS and in other demyelinating diseases and how it might be enhanced therapeutically.

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

  • In demyelinating diseases including leukoaraiosis, axons fail to fully remyelinate.

    “However, in demyelinating diseases, including leukoaraiosis, axons fail to fully remyelinate (Franklin and Ffrench-Constant, 2008).”

  • Excess intracellular Ca2+ activates protease-dependent processes that fragment microtubules and perturb axonal flow.

    “In turn, excess intracellular Ca2+ activates protease dependent processes that lead to microtubule fragmentation and perturbation of axonal flow (Franklin and Ffrench-Constant, 2008; Matute and Ransom, 2012).”

  • Loss of myelin slows axon potential transmission and threatens axon integrity, leading to axonal loss.

    “In addition to the brain dysfunction caused by slowing down the transmission of axon potentials, demyelination threatens the integrity of the axons and leads to axonal loss (Franklin and Ffrench-Constant, 2008; Matute and Ransom, 2012).”

  • Proper remyelination can restore the impaired saltatory conduction in neurons.

    “While proper remyelination can restore the impaired saltatory conduction in neurons (38), it remains unclear why remyelinating oligodendrocytes fail to overcome the demyelination observed in AD.”

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.
