Principle mechanisms of innate and adaptive immunity

Mechanisms of adaptive immunity

- acquired throughout a lifetime of an individual

- result of previous contact with pathogen

- present in vertebrates

Properties of adaptive immunity

- diversity and specificity

- memory

- clonal expansion

- autotolerance

- specialization

- stimulation of mechanisms of innate immunity
