Leukocyte signaling

Leukocyte signaling involves how white blood cells communicate to coordinate immune responses. When an infection or injury occurs, signals like chemicals (cytokines) are released, attracting leukocytes to the site. These signals bind to specific receptors on leukocytes, activating internal pathways that tell the cells to move, grow, or produce other immune factors. This process ensures an efficient defense against pathogens and helps manage inflammation, tissue repair, and immune regulation. Essentially, leukocyte signaling is the communication system that guides immune cells to detect threats and respond appropriately.
