Nav1.5 Ser571 and Age-Related Cardiac Dysfunction
2026-09-16
The 2024 study identifies Nav1.5 phosphorylation at Ser571 and increased late sodium current as an early mechanistic link between aging, delayed ventricular repolarization, and impaired diastolic function. Its combination of age-stratified mouse models, engineered channel variants, cardiac measurements, and myocyte mechanics provides a framework for testing late sodium current as a causal target in cardiac aging research.
