Immune tolerance
Immune Tolerance
Immune tolerance or immunological tolerance is the process by which the immune system does not attack an antigen. It can be either 'natural' or 'self-tolerance', in which the body does not mount an immune response to self-antigens, or 'induced tolerance', in which tolerance to external antigens can be created by manipulating the immune system.
Pronunciation
- Immune: /ɪˈmjuːn/
- Tolerance: /ˈtɒlərəns/
Etymology
The term 'immune' comes from the Latin word 'immunis', meaning 'exempt', while 'tolerance' originates from the Latin 'tolerantia', meaning 'endurance'.
