Blocking a hormone's action in immune cells may reduce heart disease risk

Blocking the mineralocorticoid receptor (MR)—a protein that helps maintain normal levels of salt and water in the body—in immune cells may help reduce the risk of heart attack and stroke by improving blood vessel health. The study will be presented today at the American Physiological Society (APS) Aldosterone and ENaC in Health and Disease: The Kidney and Beyond Conference in Estes Park, Colo.
