Manipulating calcium accumulation in blood vessels may provide a new way to treat heart disease
Hardening of the arteries, or atherosclerosis, is the primary cause of heart disease. It is caused by calcium accumulation in the blood vessels, which leads to arteries becoming narrow and stiff, obstructing blood flow and ...

Receptor (biochemistry)
In biochemistry, a receptor is a protein molecule, embedded in either the plasma membrane or cytoplasm of a cell, to which a mobile signaling (or "signal") molecule may attach. A molecule which binds to a receptor is called a "ligand," and may be a peptide (such as a neurotransmitter), a hormone, a pharmaceutical drug, or a toxin, and when such binding occurs, the receptor undergoes a conformational change which ordinarily initiates a cellular response. However, some ligands merely block receptors without inducing any response (e.g. antagonists). Ligand-induced changes in receptors result in physiological changes which constitute the biological activity of the ligands.
