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…

Through Plasma Transfer from Active Aged Mice, Sedentary Older Mice Gain Neurocognitive Benefits
TLDR
A significant correlation between increased GPLD1 concentrations in plasma and improved cognitive performance in the RAWM and contextual fear conditioning behavioral tests is observed, identifying GPLD 1 as an exercise-induced circulating blood factor in aged mice and humans with potential relevance to cognitive function in mice.
A new player in the beneficial effects of exercise on the aged brain
TLDR
The beneficial effects of physical exercise on AHN and cognition can be transferred to sedentary aged mice by injecting them with the plasma of exercised animals by using isobaric tagging together with liquid chromatography–tandem mass spectrometry.
Selenium mediates exercise-induced adult neurogenesis and reverses learning deficits induced by hippocampal injury and aging.
Exercising your mind
TLDR
It is demonstrated that the beneficial effects of exercise in mitigating brain aging can be conveyed from exercising mice to sedentary mice through plasma transfer, and compelling evidence that the positive effects of Exercise on brain aging are at least partially mediated through hepatic mechanisms is provided.
Multiple Roles in Neuroprotection for the Exercise Derived Myokine Irisin
TLDR
How exercise can positively influence brain function and mental health via the “skeletal muscle-brain axis” is discussed, with the idea that Irisin is a potentially essential mediator of the skeletal muscle- brain crosstalk put forward.
An exercise “sweet spot” reverses cognitive deficits of aging by growth-hormone-induced neurogenesis
Beneficial intergenerational effects of exercise on brain and cognition: a multilevel meta‐analysis of mean and variance
TLDR
By coupling mean with variance effects, the analyses draw a more integrated picture of the benefits that parental exercise has on offspring: not only does it improve offspring brain development and cognitive performance, but it also reduces inter-individual differences in cognition-related traits.
Exercise Factors Released by the Liver, Muscle, and Bones Have Promising Therapeutic Potential for Stroke
TLDR
This minireview will discuss the roles of exercise factors released by the liver such as beta-hydroxybutyrate, by the muscle such as lactate and irisin and by the bones such as osteocalcin and address their therapeutic potential in the context of ischemic stroke.
Harnessing the effects of endurance exercise to optimize cognitive health: Fundamental insights from Dr. Mark P. Mattson
Plasma from healthy donors protects blood–brain barrier integrity via FGF21 and improves the recovery in a mouse model of cerebral ischaemia
TLDR
It is demonstrated that healthy adult plasma treatment protected the structural and functional integrity of blood–brain barrier, reduced neuronal apoptosis and improved functional recovery via FGF21, opening a new avenue for ischaemic stroke therapy.

Vascular and Neurogenic Rejuvenation of the Aging Mouse Brain by Young Systemic Factors
TLDR
It is shown that factors found in young blood induce vascular remodeling, culminating in increased neurogenesis and improved olfactory discrimination in aging mice, and that GDF11 alone can improve the cerebral vasculature and enhance Neurogenesis.
The aging systemic milieu negatively regulates neurogenesis and cognitive function
TLDR
Heterochronic parabiosis shows that blood-borne factors present in the systemic milieu can inhibit or promote adult neurogenesis in an age-dependent fashion in mice, and identifies chemokines—including CCL11 (also known as eotaxin)—the plasma levels of which correlate with reduced neuroGenesis in heterochronics parabionts and aged mice and which are increased in the plasma and cerebrospinal fluid of healthy ageing humans.
Young blood reverses age-related impairments in cognitive function and synaptic plasticity in mice
TLDR
Exposure of aged mice to young blood late in life is capable of rejuvenating synaptic plasticity and improving cognitive function, and structural and cognitive enhancements elicited by exposure are mediated by activation of the cyclic AMP response element binding protein (Creb) in the aged hippocampus.
Exercise Enhances Learning and Hippocampal Neurogenesis in Aged Mice
TLDR
Voluntary exercise ameliorates some of the deleterious morphological and behavioral consequences of aging in mice that were sedentary until 19 months of age.
Restoring Systemic GDF11 Levels Reverses Age-Related Dysfunction in Mouse Skeletal Muscle
TLDR
It is demonstrated that the circulating protein growth differentiation factor 11 (GDF11) is a rejuvenating factor for skeletal muscle, and systemically regulates muscle aging and may be therapeutically useful for reversing age-related skeletal muscle and stem cell dysfunction.
Human umbilical cord plasma proteins revitalize hippocampal function in aged mice.
TLDR
It is shown that human Cord plasma treatment revitalizes the hippocampus and improves cognitive function in aged mice and reveals that human cord plasma contains plasticity-enhancing proteins of high translational value for targeting ageing- or disease-associated hippocampal dysfunction.
Combined adult neurogenesis and BDNF mimic exercise effects on cognition in an Alzheimer’s mouse model
TLDR
Exercise-induced AHN improved cognition along with reduced Aβ load and increased levels of brain-derived neurotrophic factor (BDNF), interleukin-6 (IL-6), fibronectin type III domain–containing protein–5 (FNDC5), and synaptic markers, however, AHN activation was also required for exercise-induced improvement in memory.
