Over the last decade, scientists have discovered the importance and widespread presence in the body of a remarkable family of proteins known as prion proteins. Research links various types of prion proteins to neurodegenerative diseases such as Parkinson's and Alzheimer's—and this has fueled the search for new drugs that could halt the progression of these terrible disorders. Other discoveries have revealed the essential roles prion proteins play in memory and immunity, and the part they may have played in the beginnings of life on our planet.

What is our immune system, and how does it work? A vast array of cells, proteins and chemicals spring into action whenever our bodies are damaged, but immunity is not something you can see, touch, or feel. It can fight off malicious bacteria and viruses, locate cancerous growths, and even rewire our brains—but sometimes our own tissues can get caught in its crossfire, with catastrophic consequences. Humans may be the most disease-ridden animals on the planet. Professor John Trowsdale shows how the immune system protects us, and how our bodies invest huge resources to keep it running.
