Abstract

Plasma transfers exercise benefit in mice: Exercise has a broad range of beneficial healthful effects. Horowitz et al. tested whether the beneficial effects of exercise on neurogenesis in the brain and improved cognition in aged mice could be transferred in plasma (blood without its cellular components) from one mouse to another (see the Perspective by Ansere and Freeman). Indeed, aged mice that received plasma from young or old mice that had exercised showed beneficial effects in their brains without hitting the treadmill. The authors identified glycosylphosphatidylinositol-specific phospholipase D1 as a factor in plasma that might, in part, mediate this favorable effect. Science , this issue p. 167 ; see also p. 144

  • The liver secretes neuroprotective molecules such as fibroblast growth factor 21 (FGF21) and glycosylphosphatidylinositol-specific phospholipase D1 (Gpld1), which are reported to prevent neuronal apoptosis, improve neurogenesis, and even prolong the lifespan of mice.

    “In addition, the liver secretes neuroprotective molecules such as fibroblast growth factor 21 (FGF21) and glycosylphosphatidylinositol-specific phospholipase D1 (Gpld1), which are reported to prevent neuronal apoptosis,222 improve neurogenesis223 and even prolong the lifespan of mice.224”
  • GPDL1 reverses age-related declines in neurogenesis and cognition in old mice.

    “GPDL1 rescues the age-related loss in neurogenesis and cognition in old mice12”
  • GPDL1 is an exercise-induced plasma protein reported to improve cognition in old mice and is also produced in the liver.

    “Notably, GPDL1–which is an exercise-induced plasma protein that has been reported to improve cognition in old mice12–is also produced in the liver.”
  • Sample size was determined from previous literature to estimate an optimal n for studies on runner plasma effects on neuroplasticity and behaviour.

    “Sample size was determined using previous literature4,10,12 to estimate an optimal n for our studies on the RP effects on neuroplasticity and behaviour.”
  • The benefits of GPLD1 and other exerkines on brain structure and function may relate to peripheral effects such as complement signalling or coagulation.

    “Hence, the benefit of GPLD1 (REF.148) and other exerkines on brain structure and function might relate to its peripheral effects, such as the complement signalling cascade149,158, or coagulation159.”

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.
