The immune system is much more interesting than I had realized, prior to taking this course. Just how can your body develop cells that can recognize and remove completely novel pathogens, without harming any of your own tissues? How do you defend against viruses that hijack your body’s cells or bacteria that replicate rapidly and evolve around your defenses? Why do we get allergies or suffer from autoimmune diseases?
Sweet like a chic-a-cherry-cola.
