Calcium signals help limit artery narrowing in older mice
Laboratory experiments in mice aged 12–14 months and 3–4 months identified a protein that helped move calcium-entry channels to the surface of older mice’s artery cells.Laboratory experiments in mice aged 12–14 months and 3–4 months identified a protein that helped move calcium-entry channels to the surface of older mice’s artery cells.
