Immune System

The Immune System The immune system is a group of cells, molecules, and tissues that help defend the body against diseases and other harmful invaders. The immune system provides protection against a variety of potentially damaging substances that can invade the body. These substances include disease-causing organisms, such as bacteria, fungi, parasites, and viruses. The body's ability to resist these invaders is called immunity. A key feature of the immune system is its ability to destroy...

Immune System and Gene Therapy

(SCID) is a rare fatal disorder that occurs in approximately 1 in 75,000 children, usually leading to infant death within one year from birth (Cavazzana-Calvo, et al. pg 202). Patients suffering from SCID have genetic mutations that prevent their immune system from properly developing and functioning, which leads to recurrent and eventually lethal infections. (Kohn, Michel, and Glorioso pg 479) Most of these patients are diagnosed with a type of SCID called X-linked SCID, which is responsible for about...

The Way the Immune System Works

THE IMMUNE SYSTEM Definition of the Immune System The human immune system is a collective network of tissues, glands, and organs that work in a coordinated effort with each other to guard our bodies from foreign antigens such as viruses, bacteria, and infection causing microorganisms. For the immune system to work properly, two things must happen: first, the body must recognize that it has been invaded, either by pathogens or toxins or by some other threat. Second, the immune response must be...
