Study Notes
Variolation and Vaccination
- "Tumangkilik" refers to variolation, an early form of immunization using dried scabs from smallpox patients.
- Latin term "Immunity" denotes exemption, applicable not just to medicine but also to taxes.
- Observations during the Peloponnesian War revealed individuals who were exempt from contracting smallpox.
- Benjamin Jesty introduced the concept of vaccination with vaccinia, laying the groundwork for Edward Jenner's later documented work with cowpox in smallpox prevention.
Historical Disease Insights
- Plague during the Peloponnesian War highlighted unsanitary conditions, with common bathing practices leading to infections.
- Bubonic plague, characterized by "bubos" or blackened skin, resulted from interactions with contaminated corpses.
- Germ theory illustrates that no causative agent equates to no disease.
Key Contributions to Immunology
- Ignaz Semmelweis emphasized hand disinfection to prevent puerperal fever in medical settings.
- Joseph Lister pioneered aseptic techniques in surgery, advocating the absence of microorganisms.
- Robert Koch developed Koch’s postulates, establishing criteria to determine specific microorganisms as causative agents of disease.
- Richard Pfeiffer's bacteriolysis phenomenon contributed to the discovery of antibiotics, such as Alexander Fleming's penicillin.
Immune System Mechanisms
- Phagocytosis involves white blood cells engulfing harmful entities.
- Paul Ehrlich introduced the concept of mast cells in tissue immunity and proposed theories on immune surveillance.
- Landsteiner classified haptens, small molecules that can trigger immune responses when bound to larger molecules.
Vaccines and Antibodies
- Various vaccines evolved, utilizing live organisms, such as cowpox for immunity against smallpox and live vaccines for cholera and anthrax.
- Immunoglobulins, including IgM and IgG, are critical in immune responses; IgM is a pentamer and indicative of agglutination when binding with antigens.
- Allo- and xenografts refer to tissue transplants from the same species and different species, respectively, with concerns regarding Graft-versus-Host Disease (GVHD) in incompatible transplants.
Immune Response Mechanisms
- Coomb’s test utilizes anti-human globulin to identify transfusion compatibility issues, focused on immunoglobulins like IgG and IgA.
- Human Leukocyte Antigen (HLA) nomenclature emerged from understanding MHC, crucial for tissue compatibility.
- Peter Nowell's discovery of interleukin 2 receptors advanced understanding of immune system communication.
- ELISA, developed by Peter Perlmann and Eva Engvall, became a vital tool in immunological testing.
