This is the fifth in a series of postings highlighting our Vaccine Makers Project animations.A new era of war has arrived. Match the parts of the adaptive immune system with the analogous role from a military unit.Ī. Watch for future animation expeditions to learn more about your immune system, diseases and vaccines. Take comfort in the fact that your immune system is battling away-even if it seems you are just resting on the couch. The next time you get sick, stop and think about what is going on inside your body. These cells constantly communicate with one another as they battle to make you better. As B cells produce more and more antibodies, fewer and fewer invaders are available to cause damage. Once the invader is attached to an antibody, it cannot infect a cell. The antibodies are shaped just right to latch on to the invaders. This two-pronged approach ensures that B cells do not respond unnecessarily. They can encounter it on the surface of another cell or they can process it directly. In addition to these signals from T cells, B cells must also encounter pieces of the invader. These chemicals, called cytokines, help to activate B cells. The dendritic cells present the pieces of the invader to T cells. Here, their arrival starts a cascade of events. They then travel to the nearest lymph node. These cells kill the invader and take a piece of it. They gather information about an invader at the site of infection. View the animation The Adaptive Immune SystemĮach type of cell of the adaptive immune system has its own special role.

What happens when germs get past your skin and mucous membranes (like the castle walls)? Then your immune system must figure out how to defend against an internal attack. People experience similar attacks from germs. Once inside, attackers were more difficult to defend against. Think of the story of the Greeks who entered Troy via the famous Trojan horse. However, attackers were sometimes successful at getting inside the walls. Both of these approaches were often in vain. Some might launch weapons at or through the walls. They often made multiple attempts to gain entry to the castle. Medieval people built those huge structures to defend themselves. How is the immune system similar to a castle?ĭo you like history? Maybe you’ve seen movies about castles. A medieval castle was built to defend against any attack.
