Leukocyte-Endothelial Interactions

Leukocyte-endothelial interactions refer to the process where white blood cells (leukocytes) communicate with and move through the lining of blood vessels (endothelium) to reach sites of infection or injury. During this process, leukocytes slow down, cling to the vessel walls, and then squeeze through the vessel lining to access tissues. This interaction involves specific signals and molecules that guide immune cells to damaged areas, helping the body defend against pathogens and promote healing. It's a vital part of the immune response, ensuring cells reach where they are needed most.
