Study Notes
Immune Response and Immunity Overview
- Phagocytes destroy microorganisms through phagocytosis and contain fluids that destroy pathogens.
- Phagocytes trigger an immune response by breaking down pathogens and generating antigens.
- Major phagocytic cells include dendritic cells, macrophages, natural killer cells, neutrophils, and eosinophils.
- Acquired immunity occurs when exposed to an infectious agent or live pathogen, subdivided into active and passive immunity.
- Passive immunity can be naturally acquired (e.g., transfer of antibodies from mother to fetus) or artificially acquired (e.g., through injection).
- Active immunity is triggered by vaccines, leading to long-term resistance but with a slow development.
- Immune response characteristics include specificity, distinguishing self from non-self molecules, and reliance on memory.
- Primary immune response is slow on first exposure to an antigen, producing activated cells and memory cells.
- Secondary immune response is faster upon second exposure, due to the rapid response of memory cells.
- Immune response can be antibody-mediated (production of antibodies) or cell-mediated (production of specialized cells to kill pathogens).
- Antibody-mediated immune response involves interactions between pathogens, innate and acquired immune systems, and the production of plasma cells and memory cells.
- Cell-mediated immune response involves macrophages presenting antigens to helper T cells, leading to activation of Tc cells that attack infected cells.
