The Confluence Of Nascar And Immunology

a: T cell ~
b: a stock car racing through the bloodstream

What: "A good analogy for this is stock car racing. If a T cell is like a stock car racing through the bloodstream and tracking down bacteria, the professional antigen presenting cells are the pit crew. The car pulls into the pit, and it is "activated" by the crew-presented with new tires and everything it needs to go racing back out on the track. For the pit crew to work, of course, it needs the right kind of tires." The link is a very informed discussion of this subject.
