The Pathological Protein

Prions are an entirely new class of pathogens, and scientists are just beginning to understand them. Although they have plagued humans and animals for 3 centuries, only in the last 2 decades have researchers linked them to diseases like Mad Cow. This book tells the strange story of their discovery, and the medical controversies that swirl around them. The author, Philip Yam, is a well-respected and connected journalist who is now an editor at Scientific American.

Doctors later discovered that Stephen had succumbed to a new kind of killer, the prion, now known to be the cause of mad cow disease in cattle, chronic wasting disease in American deer and elk, and Creutzfeldt-Jakob disease and fatal insomnia in humans, among other exotic ailments. Doctors and researchers have been aware of some of these diseases for a century and more, but only in the last two decades have scientists even begun to understand just how the pathological protein spreads to new species and kills its victims.

In this timely and intriguing book, Philip Yam describes the history of the scientific effort to track down and understand the prion, and the medical effort, still underway, to devise treatments for those who suffer from its ravages.
