HOW TO USE THIS BOOK I wrote How the Immune System Works because I couldn't find a book that would give my students an overall view of the immune system. Sure, there are as many good, thick textbooks as a person might have money to buy, but these are crammed with every possible detail. There are also lots of 'review books' that are great if you want a summary of what you've already learned -- but they won't teach you immunology. What was missing was a short book that tells, in simple language, how the immune system fits together -- a book that presents the big picture of the immune system without the jargon and the details.
How the Immune System Works is written in the form of 'lectures,' because I want to talk to you directly, just as if we were together in the classroom. This book is short, so you should be able to finish it in a few days. In fact, I strongly suggest that you sit down with this little book and read it from start to finish. The whole idea is to get an overall view of the subject, and if you read one lecture a week, that won't happen. Don't 'study' the book the first time through -- just read it and enjoy. Later you can go back and re-read the appropriate lectures as your immunology course progresses -- to keep you from losing sight of the big picture as the details get filled in.
Although the first lecture is a light-hearted overview meant to give you a running start at the subject, you'll soon discover that this is not 'baby immunology.' How the Immune System Works is a concept-driven analysis of how the immune system players work together to protect us from disease -- and why they do it this way.
In some settings, How the Immune System Works will serve as the main text for the immunology section of a larger course. In a semester-long undergraduate or graduate immunology course, your professor may use this book either as a companion to a detailed text or as the central text, supplemented by additional readings.
No matter how your professor may choose to use this book, however, you should keep one important point in mind: I didn't write How the Immune System Works for your professor. This book's for you!
