This is a commentary/editorial reviewing a Cell 2026 study (Bieri et al.) on liver-derived exerkines — factors released by the liver during exercise — and their role in reversing aging- and Alzheimer's-related memory loss via vascular mechanisms.
The reviewed study found that a liver exerkine reverses aging- and Alzheimer's-related memory loss through effects on brain vasculature, suggesting a liver-to-brain communication axis activated by exercise.
Only the publisher page and references are available — full text of this commentary is behind a paywall. Conclusions are based on the abstract-level description and cited reference, not the full commentary or the primary Cell study.
Exercise may benefit brain health in aging and Alzheimer's disease in part through liver-secreted factors acting on cerebral vasculature — clinicians should consider this biological rationale when counseling patients on physical activity.
