Principles of Immunology: The Immune System: Structure, Function, and Regulation in Health and Disease

Every immune response reflects a balance between defense and tolerance, inflammation and repair. When that balance is maintained, health is preserved. When it is disrupted, disease follows.

Principles of Immunology presents the immune system as a dynamic regulatory network that continuously coordinates defense, immune tolerance, tissue repair, and physiological adaptation. By linking fundamental immunological mechanisms to clinical medicine, it explains how immune recognition, cellular communication, and immune regulation determine host responses to infection and contribute to the pathogenesis of autoimmune disorders, allergies, chronic inflammation, and cancer.
