Cell biology: Moving in mysterious ways
Alison M. Condliffe1 & Phillip T. Hawkins
In their mission to engulf and destroy invading microorganisms, certain white blood cells (leukocytes) must leave the blood stream and migrate to the sites of infection. Such cells track their targets by following increasing concentrations of chemoattractant molecules — chemotactic gradients — until at higher concentrations the engulfment response comes into operation.
