About this ebook
The 7th Edition of How the Immune System Works by Lauren Sompayrac covers foundational immunology principles, specialized immune subsystems, and clinical applications. Published by Wiley-Blackwell, this edition breaks down complex mechanics into 16 conceptual "lectures" or chapters, using highly clear analogies to detail how immune components collaborate. [1, 2, 3, 4, 5]
Foundational Immunology Topics
- An Overview of the Immune System: A high-level introduction to how individual cellular "players" interact globally to defend the body.
- The Innate Immune System: The body's hard-wired, immediate line of defense, focusing on macrophages, neutrophils, and the complement system.
- B Cells and Antibodies: How the adaptive immune system generates specific proteins to tag and target unique pathogens.
- The Magic of Antigen Presentation: The mechanism by which specialized cells show pieces of invaders to T cells.
- T Cell Activation: The strict checkpoints required to turn on T cells safely.
- T Cells at Work: The distinct functions of helper T cells (orchestrating defenses) and killer T cells (destroying infected host cells).
- Secondary Lymphoid Organs: The structural "dating bars" (like lymph nodes and the spleen) where immune cells interact with antigens. [1, 2, 3, 4, 5]
Specialized & Systemic Subsystems
- The Intestinal Immune System: The unique defense system managing the trillions of friendly and hostile microbes in the gut.
- Immunological Memory: How the body remembers past infections to respond faster and stronger during a reinfection.
- Self-Tolerance: The selection mechanisms that prevent the immune system from attacking the body’s own healthy tissues. [1, 2, 3]
Clinical Applications & Pathology
- COVID-19: An entirely new, dedicated chapter in the 7th edition explaining how the immune system interacts with and fights SARS-CoV-2.
- Vaccines: The science behind modern immunization strategies and how they train the immune network.
- Immunodeficiency: The clinical consequences that arise when the immune system functions below full strength.
- Allergies and Autoimmunity: What happens when the immune system overreacts to harmless antigens or misidentifies self-tissues.
- Cancer and Immunotherapy: How tumors evade detection and how new medical treatments supercharge immune cells to destroy cancer. [1, 2, 3, 4]
