Study Notes
Innate Immunity
- Recognizes and responds to pathogens in a non-specific manner
- Provides immediate defense against infection
- First line of defense against infection
Acquired (Adaptive) Immunity
- Provides long-term immunity and immune memory
- Recognizes and responds to pathogens in a specific manner
- Mechanism involves T-cells and B-cells to produce clones of effector cells that induce a specific memory response in the future
- Distinguishing feature is the ability to produce a specific immune response to specific pathogens
- Main function is to provide long-term protection against specific pathogens
Cells Involved in Immunity
- Neutrophils and macrophages are always available to remove or neutralize the effect of an invader
- Involved in immediate innate immunity
- Provide immediate response to infection
Immunity in Invertebrates
- Only mechanism for protecting the body against foreign agents is innate immunity
