Marking A Target.....

a: B lymphocyte ~
b: explosive dye packs

What: "B lymphocytes are like those brightly colored explosive dye packs that bank tellers carefully tuck into stacks of bills handed over to unwary bank robbers. Once the dye pack is out of the bank's walls it gets activated. Then it explodes and covers the rest of the stolen bills in the sack with a telltale fluorescent dye." The link is a very clear discussion of how the immune system works.
