"The fact that battle cytokines such as TNF trigger the migration of DCs to a lymph node also makes perfect sense. After all, you want DCs to travel and present antigen only if a battle is on.When our Defense Department reacts to a threat to our national security, it follows the 'principle of proportional response.' For instance, if Iranian terrorists were to fire on one of our embassies, we wouldn't start dropping atom bombs on Iran. No, we would respond in a way that was more appropriate to such a limited threat. Likewise, it is important that the magnitude of an immune response be in proportion to the seriousness of the attack." -- Sompayrac, Lauren. How the Immune System Works. 2nd ed.
