In lieu of an abstract, below is the first paragraph of the paper.

The immune system of the human body serves as both an enemy and an ally. It is an ally when it constantly fights off attacks from several types of microbes. However, it is an enemy when it attacks a life-saving heart transplant or mistakenly eats away the tissues of the body (Marx, 1990). It is the job of the immune system to keep the body healthy and free of harmful substances. Researchers have been aiming for ways to suppress certain parts of the immune system while not interfering with the entire defenses of the body. By analyzing how the immune system works researchers can gain a better understanding on what might help them succeed in this process (Janeway & Travers, 2006).
