Immune System

One of the most under-celebrated systems of the body is the immune system, until it fails to do its job well. A parallel is drawn between the public safety agencies in a community which make the news with great drama during crime sprees and wildfires but otherwise operate quietly behind the scenes. This station seeks to bring the benefits of the immune system to light, with particular attention to its policing function, which calls for protecting the body from foreign invaders like bacteria, fungi and viruses as well as a more recently recognized role in protecting the body from itself by eliminating cancerous cells. Here we describe the elegant mechanisms by which white blood cells and other immune cells identify invasive organisms and wayward precancerous cells and eliminate them before they can threaten the entire organism.
