MHAE (Session 1)
A Complex System
• Allows for memory
• Can distinguish self from non self
• Makes decisions on what to do based on specific pathogens
Comparison of Innate and Adaptive Immunity
Properties
Innate Acquired
• Born with it • Acquired over time
• Rapid • Slower onset
• 1st line of defense • 2nd line of defense
• Non-specific • Specific
• Remains unchanged with • Greater and faster response with
subsequent exposures subsequent exposure
• No memory • Immunological memory
, Components
• Innate:
o Barriers
o Pattern recognition molecules
o Cells (e.g. Neutrophils, basophils, eosinophils, monocytes,
macrophages, dendritic cells, mast cells)
• Adaptive:
o B-cells
o T-cells
