In the Viral Attack comic, the body's fight against invaders was a success, thanks to the important work of key immune cells. But what more do we know about how these cells work as they fight off an attack from harmful viruses? That's what the "behind the scenes" section is all about.
As you click through the comic, the information buttons will take you directly to more in-depth information on the different cells you see. But you can also click on the links below to take you to a full page about each of these players in the story.
|Epithelial cells||Epithelial cells are one of the body's first lines of defense against invaders. These cells make up your skin, including the inside of other areas, like your mouth. But sometimes viruses sneak past these barriers.|
|Macrophages||Macrophages are one of the first cells to arrive at an infection. Infected or injured cells release chemicals to attract macrophages. These "big eaters" can clean up infected cells, bacteria, and viruses.|
|Neutrophils||Neutrophils are short-lived cells that arrive to the scene of the infection very early, alongside macrophages. They have many weapons to fight off invaders, but some of those also harm the body's other cells. Neutrophils also alert many other cells that more help is needed.|
|T-cells||Two types of T-cells are very important to fighting infection. Helper T-cells coordinate the attack on invaders, and Killer T-cells destroy infected cells, helping to stop the spread.|
|B-cells||B-cells play a very important role in immune defense. When you fight a specific virus, they are responsible for making antibodies. That helps you fight off the viruses in a targeted way, finishing the fight.|
|Memory cells||T and B-cells are also important as memory cells. Memory cells live on after the battle and help your body remember those specific invaders. That way, you can fight them off faster if they appear again.|
