Study Notes
Innate Immunity
- Innate immunity is fast and non-specific.
- The role of innate immunity in stimulating adaptive immunity is to activate and coordinate the response of adaptive immune cells.
- Components of innate immunity include: • Physical barriers (skin, mucous membranes) • Cellular components (phagocytes, granulocytes, dendritic cells) • Humoral components (complement system, cytokines, interferon)
- Attributes of innate immunity include: • Non-specific recognition • Immediate response • Lacks immunological memory
- The function of innate immunity is to provide immediate defense against infection and trigger an adaptive immune response.
Adaptive Immunity
- Adaptive immunity is acquired and specific.
Components of Innate Immunity
- The component of innate immunity that involves the use of cytokines and interferon is the humoral component.
Role of Phagocytes and Granulocytes
- Phagocytes and granulocytes recognize and engulf foreign particles and microorganisms, playing a key role in eliminating pathogens from the body.
Programmed Enzymes and Undead
- Programmed enzymes and undead refer to apoptosis (programmed cell death) and necrosis (unprogrammed cell death), which help eliminate infected cells and prevent the spread of infection.
