Protective actions of exercise‐related FNDC5/Irisin in memory and Alzheimer’s disease
Bibliographic record
Abstract
The proportion of elderly populations is rapidly booming, and human lifespan has considerably increased in the past century because of scientific and medical advances. However, the winds of change brought by the 21st century made sedentarism one of the factors that renders the brain vulnerable to age-related chronic diseases, such as Alzheimer's disease (AD). Conversely, physical exercise has been shown to stimulate molecular mechanisms beneficial to cognition. Here, we review evidence showing the positive effects of physical exercise in the brain. We further discuss recent evidence that irisin, a myokine stimulated by physical exercise derived from fibronectin type III domain-containing protein 5 (FNDC5) transmembrane protein, has neuroprotective actions in the brain. Lastly, we highlight the importance of the crosstalk between the periphery and the brain in cognition and the therapeutic potential of FNDC5/irisin in AD.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
