Klotho (alpha-Klotho) for Longevity
Anti-aging hormone; soluble klotho boosts cognition and modulates phosphate/FGF23 axis.
Why Klotho (alpha-Klotho) for longevity?
Alpha-Klotho is a single-pass transmembrane protein with a shed soluble form that acts as a circulating hormone. Klotho-overexpressing mice live ~30% longer; klotho-deficient mice age prematurely. Dena Dubal's lab (UCSF, 2014, 2020) showed that exogenous soluble klotho improves cognition in aged mice and primates. Human trials remain limited.
Longevity context: Targeting senescent cells, mitochondrial function, telomere maintenance, and cellular resilience. Klotho (alpha-Klotho) fits this goal because its category (Longevity) and benefit profile align with the underlying mechanism.
Benefits relevant to longevity
- Cognitive enhancement (preclinical)
- Phosphate homeostasis
- Anti-fibrotic in kidney models
