Key Concepts

Innate Immune System

Refers to the body's first line of defense that is present at birth. It provides an immediate, non-specific response to pathogens using barriers, cells, and various proteins designed to recognize common patterns found on many microorganisms.

Adaptive Immune System

Develops over time and specifically targets pathogens with tailored responses. It is characterized by its ability to improve its response upon re-exposure to the same pathogen through high specificity and the generation of memory cells.

Immunological Memory

A key feature of the adaptive immune system, where previous encounters with pathogens prime the immune response, resulting in a faster and stronger reaction upon subsequent exposures. This concept is crucial for long-lasting protection and effective vaccination strategies.
