Study Notes
Introduction to Immunology
- Immunology is the study of the immune system, its components, and how it protects the body from disease.
- This introductory course focuses on the basic principles of immunology relevant to students in Biotechnology and Genetic Engineering.
Course Structure and Learning Objectives
- Interactive lectures incorporating PowerPoint presentations, pre-made CD animations, educational movies, and flow cytometry demonstrations.
- The course aims to provide students with a solid foundation in immunology and prepare them for graduate studies if they choose to pursue them.
Key Concepts Covered
- Components of the immune system: organs, cells, and molecules.
- Principles of innate and adaptive immunity: how the body defends against pathogens.
- Recognition and effector mechanisms: how the immune system identifies threats and responds.
Historical Evolution of Immunology
- Early observations of immunity date back to the 5th century BC with descriptions of immunity from plagues.
- The 15th century saw the first attempts to induce immunity intentionally through variolation.
- Edward Jenner developed the first vaccine in 1796 using cowpox to protect against smallpox.
- Robert Koch in the late 1800s demonstrated that microorganisms cause infectious diseases.
- Louis Pasteur developed a vaccine for anthrax and rabies.
- Emil Von Behring and Shibaaburo Kitasato discovered antibodies in the blood of immune individuals.
- Elie Metchnikoff discovered phagocytes, cells that ingest and destroy foreign material.
Innate and Adaptive Immunity
- Innate immunity (non-specific): acts as the first line of defense, providing immediate protection against a wide range of pathogens.
- Adaptive immunity (specific): develops over time in response to a specific pathogen, creating a memory of the encounter for future protection.
Components of Innate Immunity
- Physical barriers: skin, mucous membranes, cilia.
- Physiological barriers: low pH, antimicrobial substances (lysozyme, interferons), complement proteins.
- Cellular barriers: phagocytes (macrophages, neutrophils, dendritic cells), which engulf and destroy pathogens.
Key Terms
- Antigens: substances that trigger an immune response.
- Immunogens: substances that induce an adaptive immune response.
- Antibodies: proteins produced by the immune system that bind to antigens.
- Phagocytosis: process by which cells engulf and destroy foreign material.
- Opsonization: coating of pathogens with antibodies or other proteins to enhance phagocytosis.
Role of Phagocytes
- Phagocytes are crucial for both innate and adaptive immunity.
- They destroy pathogens and contribute to the development of adaptive immune responses.
- Ingestion of foreign material by phagocytes leads to its destruction and the development of acquired immunity.
Adaptive Immunity: The Specific Immune Response
- Adaptive immunity is characterized by its specificity to particular pathogens.
- It is mediated by lymphocytes (B cells and T cells).
- Adaptive immunity can provide lifelong protection against certain pathogens.
