Cytotoxic T cells (CTLs), also known as Killer T cells, are a special type of T cells with the ability to kill other cells. Usually they kill cells that have been infected with a virus. This way the virus can no longer use these cells for replicating inside of them. CTLs secrete cytotoxins to kill the other cells and are therefore called “cytotoxic” T cells.
Below is a video showing a killer T cell killing a target cell. How amazing is our immune system!
And here are some Killer T Cell stickers and postcards you might like!
