Introduction to Immunology
Professor Dave Explains・2 minutes read
Microorganisms are everywhere, but the immune system prevents constant sickness by providing adaptive immunity through vaccines, as seen with smallpox survivors and key discoveries by scientists like Elie Metchnikoff and Emil von Behring in the late 1800s. The debate between the cellular and humoral theories of immunity was resolved by understanding that both components work together, forming a complex system of tissues, cells, and molecules defending against pathogens.
Insights
- Understanding the immune system helps explain why we are not constantly sick despite the presence of disease-causing microorganisms all around us.
- Historical figures like Elie Metchnikoff and Emil von Behring made significant contributions to the understanding of the immune system, leading to the resolution of the debate between cellular and humoral theories and highlighting the complex yet coordinated defense mechanisms involving tissues, cells, and molecules.
