Abstract

Remyelination is a regenerative process in the central nervous system (CNS) that produces new myelin sheaths from adult stem cells. The decline in remyelination that occurs with advancing age poses a significant barrier to therapy in the CNS, particularly for long-term demyelinating diseases such as multiple sclerosis (MS). Here we show that remyelination of experimentally induced demyelination is enhanced in old mice exposed to a youthful systemic milieu through heterochronic parabiosis. Restored remyelination in old animals involves recruitment to the repairing lesions of blood-derived monocytes from the young parabiotic partner, and preventing this recruitment partially inhibits rejuvenation of remyelination. These data suggest that enhanced remyelinating activity requires both youthful monocytes and other factors, and that remyelination-enhancing therapies targeting endogenous cells can be effective throughout life.

  • Older patients are likely to remain receptive to regenerative therapies.

    “Thus, older patients are likely to remain receptive to regenerative therapies, which is in line with the conclusions drawn from experimental mouse models (41).”

    From BCAS1 expression defines a population of early myelinating oligodendrocytes in multiple sclerosis lesions (2017) · cites this paper as [41]

    The Discussion concludes that aged oligodendrocyte progenitor cells remain responsive to signals that promote repair and identifies them as potential targets for remyelination therapy, including in MS patients. The claim extends that conclusion from a specific CNS repair process to older patients’ receptiveness to regenerative therapies generally. (LLM, conf=0.84)

  • Microglia/macrophages exhibit regenerative properties through the phagocytosis of myelin debris and secretion of growth/neurotrophic factors.

    “they also exhibit regenerative properties through the phagocytosis of myelin debris3, 4 and secretion of growth/neurotrophic factors5.”
  • Pairing of an old animal with a young animal (Y/O) led to increased densities of M2 microglia/macrophages in the lesions in the older animal relative to O/O pairings.

    “Pairing of an old animal with a young animal (Y/O), a manipulation that restores remyelination efficiency in the older animal4, led to increased densities of M2 microglia/macrophages in the lesions in the older animal relative to those seen in the O/O pairings (Fig. 6b, c).”
  • Macrophages remove myelin debris to promote myelin regeneration and reverse age-related dedifferentiation of oligodendrocytes.

    “macrophages remove myelin debris to promote myelin regeneration and reverse the age-related dedifferentiation of oligodendrocytes,433”
  • Blood-borne factors also influence stem cell changes in the aging central nervous system.

    “This surgical intervention also enhances rates of neurogenesis, remyelination and other measures of neural function in the old parabiont, suggesting that changes in stem cell function in the aging central nervous system are also affected by blood-borne factors165–167.”

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.
