IMMUNE-SYSTEM - Study finds that fast-moving cells in the human immune system walk in a stepwise manner

A team of biologists and engineers at the University of California, San Diego has discovered that white blood cells, which repair damaged tissue as part of the body's immune response, move to inflamed sites by walking in a stepwise manner. The cells periodically form and break adhesions mainly under two "feet," and generate the traction forces that propel them forward by the coordinated action of contractile proteins. Their discovery, published M ...
