White Blood Cell Grabbing a Bacterium  by Thabe Matsebatlela

This micrograph shows what goes on inside our bodies when we are infected with bacteria, and how cells of the immune system carry out the searching and killing of bacteria to remove the infection. This is a magnified view (5,000x) of what happened when white blood cells of the immune system (macrophages) were challenged with bacteria for 30 minutes: these cells were able to search, grab, attack, and eliminate the bacteria. The membrane protrusions of the white blood cells are essential in achieving this purpose, and drugs that enhance these elongation actions will be useful in activating immune system cells to kill bacteria.
