Description

The human immune system is a remarkable defense network that protects the body against infections, foreign substances, and disease. This book provides a clear, structured, and comprehensive exploration of immunology, beginning with the fundamentals of innate (non-specific) and adaptive (specific) immunity, and progressing into advanced concepts such as immune regulation, antibody structure and function, and clinical immune disorders.

Readers will gain a deep understanding of:

The innate immune system, including inflammation, the complement system, and first-line defense mechanisms. The adaptive immune system, with detailed coverage of humoral immunity, antibody types (IgA, IgD, IgE, IgG, IgM), and cell-mediated immunity involving T cells and antigen-presenting cells. The role of the major histocompatibility complex (MHC), T cell activation, cytokines, and immunological memory. Clinical applications, including immunization, vaccination schedules, autoimmune diseases, immune deficiencies, and hypersensitivity reactions.

This book is written to serve medical students, life science graduates, and healthcare professionals, offering both conceptual clarity and clinical relevance. With well-structured explanations, easy-to-follow tables, and detailed coverage of antibodies and immune pathways, it is an essential reference for understanding how immunity works in health and disease.
