    All living things are made of cells. In the human body, these highly efficient units are protected by layer upon layer of defense against icky invaders like the cold virus. Shannon Stiles takes a journey into the cell, introducing the microscopic arsenal of weapons and warriors that play a role in the battle for your health.
    Lesson by Shannon Stiles, animation by Igor Coric.

    mmmm that's not quite how it works in the beginning. Dendritic cells snipe and consume one or two viruses on purpose and then dismember them. They then display body parts on the outside of the cell wall and travel to a lymph node where they communicate with T and B cells about the invader. There is no.....Trojan horse..... :/

    No. A virus injects it’s DNA into the cell, to make the cell release more viruses. It is the dendritic cell that warns T and B cells about it. The B cells make antibodies, and the T cells kill the infected cells with cytotoxins. It’s much more complicated.
