Innate Immunity — Broadly Specific Host Defenses, PRRs, and Complement System Explained | Chapter 26 from Brock Biology of Microorganisms
Innate Immunity — Broadly Specific Host Defenses, PRRs, and Complement System Explained | Chapter 26 from Brock Biology of Microorganisms How does the human body rapidly defend itself against diverse pathogens, even before specific immune memory develops? Chapter 26 of Brock Biology of Microorganisms introduces the core principles of innate immunity—a fast, non-specific defense system that stands as our first line of protection. This summary covers the main cells, molecules, and mechanisms of innate immunity, explains how pathogens are recognized and eliminated, and highlights the vital links between innate and adaptive immune responses.

Innate vs. Adaptive Immunity: The Body’s Two-Tiered Defense Innate immunity is present from birth, acts rapidly, and is broadly specific rather than highly targeted. Key cells include phagocytes (neutrophils, macrophages) ...
