How the Immune System Works

How the Immune System Works, 7th Edition is a concise textbook designed to clarify core biological mechanisms and host defense responses. Written by Lauren M. Sompayrac, the text introduces foundational immunology principles to help readers understand cellular signaling, pathogen defense, and systemic immunity within introductory medical science studies.

The content unfolds across seventeen structured lectures, beginning with the innate immune system, B cells, antibodies, and antigen presentation. It moves through T cell activation, helper and killer T cells, secondary lymphoid organs, and lymphocyte trafficking, before addressing immune restraint, self tolerance, MHC restriction, immunological memory, the intestinal immune system, and immunodeficiency.

To assist study preparation, each lecture includes heads up! boxes that outline upcoming chapter material. Published by Wiley-Blackwell in a 176-page format, this volume provides structured support for foundational immunology coursework.
