(19 15 was born in Rio de Janeiro on February 28th, and 1987 died in London, England on February 2nd). Brazilian-born British zoologist was awarded the Nobel Prize in Physiology or Medicine by Sir Frank MacFarlane Bernitt in 1960. He successfully paved the way for organ and tissue transplantation in developing countries and proved the theory and model of acquired immune tolerance. Medawar was born in Brazil and moved to England as a child. 1935 received degrees in zoology from Magdalene College and Oxford University, and 1938 became a researcher in the college. During World War II, he organized transplantation, especially skin transplantation, in the Burn Department of the Royal Hospital in Glasgow, Scotland. This work made him realize that transplant rejection is an immune response. After the war, Medawar continued his research and transplanted the experience gained from frank mcfarlane burnett's work. He first obtained the advanced theory of immune tolerance. According to this hypothesis, vertebrates developed the ability to distinguish substances belonging to their own bodies from those with foreigners in the early embryonic development and shortly after birth. This view contradicts the view that vertebrates can inherit this concept. When Medawar used this to support Bernitt's theory, he found that twin brothers and cows received skin transplants from each other, which indicated that some antigenic substances were called "leaking" from each pair of embryo yolk sacs to other paths. In experiments on mice, his evidence shows that although each animal cell contains some genes that determine important immune processes, tolerance can also be obtained, because the recipient as a donor will receive body parts from various tissue donors and twin brothers from donors. Medawar's work has turned the focus of immunology to a scientific hypothesis, the all-round development of immune mechanism, and attempts to change autoimmune mechanism, such as trying to suppress human organ transplant rejection. Medawar is a professor of zoology at Birmingham University (1947- 195 1) and University College London (195 1- 1962). He is a professor at the London Institute of Medicine (1962). Professor of Experimental Medicine of Royal Society (1977- 1983), Chairman and Royal Medical Graduate School (198 1- 1987). In 1965 and 198 1, he was awarded the medal of honor by the knight. Medawar's works include Individual Uniqueness (1957), Future of Mankind (1959), Dissolved Art (1967), Hope for Progress (1972) and Life Science. Very good. You can try.
