Abstract

Help the Aged: Muscle function declines with age, as does neurogenesis in certain brain regions. Two teams analyzed the effects of heterochronic parabiosis in mice. Sinha et al. (p. 649 ) found that when an aged mouse shares a circulatory system with a youthful mouse, the aged mouse sees improved muscle function, and Katsimpardi et al. (p. 630 ) observed increased generation of olfactory neurons. In both cases, Growth Differentiation Factor 11 appeared to be one of the key components of the young blood.

  • Preclinical studies have demonstrated that GDF11 in young plasma exerts neuroprotective effects by promoting neurogenesis within the hippocampus and enhancing learning and memory in aged mice.

    “Preclinical studies have demonstrated that growth differentiation factor-11 (GDF11) in young plasma exerts neuroprotective effects by promoting neurogenesis within the hippocampus and enhancing learning and memory in aged mice.72”
  • The levels of antiageing factors such as GDF11, TIMP2 and CSF2 are reduced; these factors are linked to improved microglial phagocytosis and neurogenesis and reduce the amyloid-β load, thus enhancing cognition.

    “In contrast, the levels of antiageing factors, such as GDF11, tissue inhibitor of metalloproteinase 2 (TIMP2) and granulocyte‒macrophage colony stimulating factor (CSF2), are reduced. These factors are linked to improved microglial phagocytosis and neurogenesis and reduce the Aβ load, thus enhancing cognition.72,322–324”
  • In old mice, extra GDF11 reverses cardiac hypertrophy, improves neural stem cell and neuronal function, and increases physical activity.

    “GDF11 supplementation in old mice further reverses age-related hypertrophy in cardiac muscle168, enhances neural stem cell and neuronal function166 and improves physical activity38.”
  • The same surgery raises neurogenesis, remyelination and other neural function measures in the older parabiont.

    “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.”
  • 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.
