Leukocyte adhesion

Leukocyte adhesion is a vital part of the immune response, where white blood cells (leukocytes) move from the blood into tissues to fight infection or heal injury. When a threat is detected, the blood vessel walls signal the leukocytes to slow down and stick to the vessel’s lining through specific proteins called adhesion molecules. This process allows the leukocytes to exit the bloodstream and reach the affected area, where they can combat pathogens or assist in tissue repair. Effective adhesion is essential for a proper immune response and maintaining health.
