VIRUSES lesson 9: The Body Fights Back

Free Preview

 

In this lesson we will take a very brief look at some of the strategies the immune system uses to fight viruses.  Most of the time the body wins the fight, even with viruses having so many ways to get around the cell’s biological weapons.

NOTE:  There is an optional intermission at the 32 minute mark (total running time is 59 minutes)

SUPPLEMENTAL VIDEOS:

Here is a 5-minute overview of the immune system.  It focuses more on bacteria, so they show “neutrophils” instead of NK cells.  However, you will see many things we discussed during the drawing lesson.

 

Here is a combination of actual footage and computer generated animations showing macrophages at work.  The video shows macrophages attacking bacteria, but the principle is the same for viruses, especially if they are coated in antibodies.

 

Here is an animation about Natural Killer cells.  Though produced by a professional scientific animation company, this video contains a glaring error.  We see a bacteriophage virus attacking a body cell, which, as you know, is impossible, since bacteriophages attack only bacteria.  This a common error.  Bacteriophages look so interesting that people are tempted to use them any time they want to depict “a virus.”  (How do I know the bacteriophage is attacking a body cell?  Look at the MHC-1 flag right there in front of the phage, in the bottom right corner of the picture.)
