VCAM-1 (Vascular Cell Adhesion Molecule 1)

VCAM-1 (Vascular Cell Adhesion Molecule 1) is a protein found on the surface of blood vessel cells. It plays a crucial role in the immune system by helping white blood cells stick to blood vessel walls and move into tissues where they are needed, such as during inflammation or infection. VCAM-1 acts like a molecular "hand" that captures passing immune cells, guiding them to sites of injury or disease. Its activity is tightly regulated, and abnormal levels can be associated with conditions like cardiovascular disease, cancer, and autoimmune disorders.
