Décès du Nobel de Médecine Rita Levi-Montalcini à l’âge de 103 ans

Décès du Nobel de Médecine Rita Levi-Montalcini à l’âge de 103 ans

Une grande Dame s’en est allée. Parce que juive, elle ne pourra pas se spécialiser en neurologie et psychiatrie comme elle l’aurait souhaité. Elle obtiendra pourtant le prix Nobel de médecine en 1987. Voir son autobiographie en fin d’article.

La scientifique et Prix Nobel de Médecine Rita Levi-Montalcini, connue pour ses importantes découvertes sur les neurones, est décédée dimanche à son domicile romain à l’age de 103 ans, a indiqué l’agence de presse Ansa. Née à Turin le 22 avril 1909 d’un père ingénieur et d’une mère peintre, elle entame à 20 ans des études de médecine qu’elle achève brillamment en 1936.

La promulgation des lois raciales en Italie empêche la jeune femme d’origine juive de poursuivre sa spécialisation en neurologie et psychiatrie.  Pendant la guerre, elle installe un laboratoire de fortune dans sa cuisine puis dans sa maison de campagne piémontaise où elle mène des expérimentations sur les embryons de poulets. Ses découvertes sur les poulets, pourtant réalisées dans des conditions précaires, lui valent en 1947 une invitation à la Washington University de Saint Louis dans le Missouri.

Elle y restera trente ans, poursuivant sa carrière en tant que chercheuse et enseignante, tout en dirigeant l’Institut de biologie cellulaire du Centre national de la recherche à Rome. En 1986, elle obtient la reconnaissance internationale grâce au Prix Nobel de Médecine reçu en collaboration avec Stanley Cohen pour la découverte révolutionnaire des « facteurs de croissance de cellules nerveuses » (nerve growth factor, NGF).

Cette découverte, « d’une importance fondamentale » selon les motivations du jury, a permis de mieux comprendre le développement du système nerveux et de faire d’énormes progrès dans l’étude des maladies cérébrales comme la maladie d’Alzheimer, des complications neurologiques liées au diabète et certains phénomènes cancéreux. En août 2001, le président de la République italienne Carlo Azeglio Ciampi l’avait nommée sénatrice à vie pour « ses grands mérites dans le champ scientifique et social ».

Elle présidait en outre une fondation à son nom, créée en 1992 et destinée à financer les études de femmes africaines, en Ethiopie, au Congo et en Somalie notamment, et de jeunes dans le besoin.

Rita Levi-MontalciniMy twin sister Paola and I were born in Turin on April 22, 1909, the youngest of four children. Our parents were Adamo Levi, an electrical engineer and gifted mathematician, and Adele Montalcini, a talented painter and an exquisite human being. Our older brother Gino, who died twelve years ago of a heart attack, was one of the most well known Italian architects and a professor at the University of Turin. Our sister Anna, five years older than Paola and myself, lives in Turin with her children and grandchildren. Ever since adolescence, she has been an enthusiastic admirer of the great Swedish writer, the Nobel Laureate Selma Lagerlöf, and she infected me so much with her enthusiasm that I decided to become a writer and describe Italian saga « à la Lagerlöf ». But things were to take a different turn.

The four of us enjoyed a most wonderful family atmosphere, filled with love and reciprocal devotion. Both parents were highly cultured and instilled in us their high appreciation of intellectual pursuit. It was, however, a typical Victorian style of life, all decisions being taken by the head of the family, the husband and father. He loved us dearly and had a great respect for women, but he believed that a professional career would interfere with the duties of a wife and mother. He therefore decided that the three of us – Anna, Paola and I – would not engage in studies which open the way to a professional career and that we would not enroll in the University.

Ever since childhood, Paola had shown an extraordinary artistic talent and father’s decision did not prevent her full-time dedication to painting. She became one of the most outstanding women painters in Italy and is at present still in full activity. I had a more difficult time. At twenty, I realized that I could not possibly adjust to a feminine role as conceived by my father, and asked him permission to engage in a professional career. In eight months I filled my gaps in Latin, Greek and mathematics, graduated from high school, and entered medical school in Turin. Two of my university colleagues and close friends, Salvador Luria and Renato Dulbecco, were to receive the Nobel Prize in Physiology or Medicine, respectively, seventeen and eleven years before I would receive the same most prestigious award. All three of us were students of the famous Italian histologist, Giuseppe Levi. We are indebted to him for a superb training in biological science, and for having learned to approach scientific problems in a most rigorous way at a time when such an approach was still unusual.

In 1936 I graduated from medical school with a summa cum laude degree in Medicine and Surgery, and enrolled in the three year specialization in neurology and psychiatry, still uncertain whether I should devote myself fully to the medical profession or pursue at the same time basic research in neurology. My perplexity was not to last too long.

In 1936 Mussolini issued the « Manifesto per la Difesa della Razza », signed by ten Italian ‘scientists’. The manifesto was soon followed by the promulgation of laws barring academic and professional careers to non-Aryan Italian citizens. After a short period spent in Brussels as a guest of a neurological institute, I returned to Turin on the verge of the invasion of Belgium by the German army, Spring 1940, to join my family. The two alternatives left then to us were either to emigrate to the United States, or to pursue some activity that needed neither support nor connection with the outside Aryan world where we lived. My family chose this second alternative. I then decided to build a small research unit at home and installed it in my bedroom. My inspiration was a 1934 article by Viktor Hamburger reporting on the effects of limb extirpation in chick embryos. My project had barely started when Giuseppe Levi, who had escaped from Belgium invaded by Nazis, returned to Turin and joined me, thus becoming, to my great pride, my first and only assistant.

The heavy bombing of Turin by Anglo-American air forces in 1941 made it imperative to abandon Turin and move to a country cottage where I rebuilt my mini-laboratory and resumed my experiments. In the Fall of 1943, the invasion of Italy by the German army forced us to abandon our now dangerous refuge in Piemonte and flee to Florence, where we lived underground until the end of the war.

In Florence I was in daily contact with many close, dear friends and courageous partisans of the « Partito di Azione ». In August of 1944, the advancing Anglo-American armies forced the German invaders to leave Florence. At the Anglo-American Headquarters, I was hired as a medical doctor and assigned to a camp of war refugees who were brought to Florence by the hundreds from the North where the war was still raging. Epidemics of infectious diseases and of abdominal typhus spread death among the refugees, where I was in charge as nurse and medical doctor, sharing with them their suffering and the daily danger of death.

The war in Italy ended in May 1945. I returned with my family to Turin where I resumed my academic positions at the University. In the Fall of 1947, an invitation from Professor Viktor Hamburger to join him and repeat the experiments which we had performed many years earlier in the chick embryo, was to change the course of my life.

Although I had planned to remain in St. Louis for only ten to twelve months, the excellent results of our research made it imperative for me to postpone my return to Italy. In 1956 I was offered the position of Associate Professor and in 1958 that of Full Professor, a position which I held until retirement in 1977. In 1962 I established a research unit in Rome, dividing my time between this city and St. Louis. From 1969 to 1978 I also held the position of Director of the Institute of Cell Biology of the Italian National Council of Research, in Rome. Upon retirement in 1979, I became Guest Professor of this same institute.
