Liven up your A&P class with a great video showing a gruesome attack by a killer T cell on a cancer cell. It's a fantastic bit of video microscopy produced by Cambridge University.
Okay, with the oddly soothing music score instead of a more appropriate score for the graphic violence shown in this video, it's not much of a horror flick. Especially when you consider that it's the "bad guy" cell getting whacked. But it is graphic and dramatic and impressive.
Just the thing to liven up a discussion of adaptive immunity, which (let's face it) can often cause a catatonic state in many students.
It's a free resource available on YouTube.
