leukocyte infiltration

Leukocyte infiltration refers to the movement of white blood cells (leukocytes) from the bloodstream into tissues, usually in response to infection or injury. This process is part of the body's immune response, aiming to identify, contain, and eliminate harmful pathogens or damaged cells. When tissues detect a threat, signals attract leukocytes to the affected area, where they help fight infection and promote healing. While essential for defense, excessive or prolonged infiltration can contribute to inflammation and tissue damage. This process is a vital aspect of the body's effort to protect and heal itself.
