Blood pressure is controlled in part by changes in the radius of blood vessels; when the smooth muscle cells in the wall of a blood vessel contract, the radius of the blood vessel decreases and blood pressure increases. Researchers have now identified in mice a new signaling pathway that contributes to relaxation of smooth muscle cells in blood vessel walls triggered by the molecule NO and thereby decreases blood pressure.
