|Peter Medawar, Frank Macfarlane Burnet immunology|
- Mac Burnet predicted it.
- Peter Medawar discovered it.
- People were dying of transplants—
- kidney transplants often killed;
- spleen transplants often killed.
- Medawar, a British zoologist
- who had treated victims burned in the Blitz
- experimented with skin-grafts on animals.
- Influenced by Burnet, Medowar discovered, in mice,
- the process of immunity acquired in the womb
- by exposure to skin from a particular donor,
- after which the mice were able to tolerate skin grafts
- from the same donor.
- This discovery led to an understanding
- and the development of drugs
- to suppress the immune system for transplants.
- By default our bodies reject
- anything they don’t recognize.
- Abnormalities can result
- in various autoimmune disease.
- Fetuses acquire tolerance in pregnancy.
- Adults can acquire it orally.
- We can learn tolerance.
- We can learn to calm our fears.
- Any one of many lambs in the fold
- all look the same to us
- but the mother knows her own.
- Our own innocent babies,
- snotty, wet, and crying,
- always look beautiful to us.
