Study Notes
Immunity
- Individuals who previously had a particular disease often develop immunity to it.
- The concept of immunity is based on the ability to distinguish between "self" (normal body cells) and "non-self" (foreign invaders).
- Immunity can also be influenced by factors related to the disease-causing agent, the host's health, and the route of infection.
Benjamin Jesty
- Jesty recognized that people who had previously had a disease, or something similar, didn't get it again.
- He studied immunity and the use of vaccines before Edward Jenner.
- Jesty discovered the vaccinia famillia virus.
Edward Jenner
- Jenner is credited with discovering the first vaccine.
- Jenner developed a vaccine to prevent smallpox.
- Though Jesty discovered a similar vaccine, Jenner is given more credit because he reported his findings more effectively.
Pathogen-Associated Molecular Patterns (PAMPs)
- PAMPs are conserved molecular structures found in pathogens, but not in host cells.
- They are recognized by the immune system.
- Examples of PAMPs include bacterial lipopolysaccharides (LPS) and viral RNA.
- PAMPs help the innate immune system quickly identify pathogens.
Damage-Associated Molecular Patterns (DAMPs)
- DAMPs are molecules released by stressed or damaged cells in the body.
- They are also recognized by the immune system.
- DAMPs can trigger inflammation and immune responses to repair damaged tissues.
