Illustration showing a white blood cell (purple) leaving a blood vessel (pink, bottom) at the site of an infection. Certain types of white blood cell, including dendritic cells (blue) can release small signal proteins collectively termed cytokines (red dots). By moving towards high concentrations of cytokines (chemotaxis), more white blood cells can travel to the site of an infection. | |
