- How lymphocytes recognise their own cells
- There are probably around 10 million different lymphocytes, each capable of recognising a different chemical shape
- In the fetus, these lymphocytes are constantly colliding with other cells
- Infection in the fetus is rare because it is protected from the outside world by the mother and, in particular, the placenta
- Lymphocytes will therefore collide almost exclusively with the bodys own material
- Some of the lymphocytes will have receptors that exactly fit those of the body's own cells
- These lymphocytes either die or are suppressed
- The only remaining lymphocytes are those that fit foreign material and therefore only respond to foreign material
- These lymphocytes either die or are suppressed
