Happy 101st birthday Rita Levi-Montalcini!

The Italiani all'estero Group invites you to celebrate Rita Levi-Montalcini's birthday on April 22 at 9 pm Italian time (12 noon Arizona time).
Rita Levi-Montalcini was born on April 22, 1909 in Turin, Italy. She shared with biochemist Stanley Cohen the Nobel Prize for Physiology or Medicine in 1986 for her discovery of a bodily substance that stimulates and influences the growth of nerve cells. She holds dual citizenship in Italy and the United States.
Levi-Montalcini studied medicine at the University of Turin and did research there on the effects that peripheral tissues have on nerve cell growth. Forced into hiding in Florence during the German occupation of Italy (1943?45) because of her Jewish ancestry, she was able to resume her research at Turin after the war.
In 1947 she accepted a post at Washington University, St. Louis, Missouri, with the zoologist Viktor Hamburger, who was studying the growth of nerve tissue in chick embryos. In 1948 it was discovered in Hamburger's laboratory that a variety of mouse tumor spurred nerve growth when implanted into chick embryos. Levi-Montalcini and Hamburger traced the effect to a substance in the tumor that they named nerve-growth factor (NGF). Levi-Montalcini further showed that the tumor caused similar cell growth in a nerve-tissue culture kept alive in the laboratory, and Stanley Cohen, who by then had joined her at Washington University, was able to isolate the NGF from the tumor. NGF was the first of many cell-growth factors to be found in the bodies of animals. It plays an important role in the growth of nerve cells and fibers in the peripheral nervous system. Levi-Montalcini remained active in the field, working at Washington University until 1961 and afterward at the Institute of Cell Biology in Rome. An autobiographical work, In Praise of Imperfection, was published in 1988.
HAPPY BIRTHDAY RITA!
