Rita Levi-Montalcini

Rita Levi-Montalcini (1909–2012) was an Italian neurobiologist who discovered nerve growth factor and shared the 1986 Nobel Prize in Physiology or Medicine.

Stanley Cohen: An American biochemist who shared the 1986 Nobel Prize for discoveries about growth factors. He collaborated with Levi-Montalcini to isolate and characterize nerve growth factor.
Nerve growth factor: A signaling protein that supports the survival, growth, and maintenance of certain neurons. This is the molecule Levi-Montalcini discovered and investigated.
Turin: A city in northwestern Italy and a major center of Italian science and industry. Levi-Montalcini began her medical and neuroembryological work there.
Neurodevelopment: The processes through which the nervous system forms, matures, and becomes functional. Nerve growth factor demonstrated that chemical signals help shape neuronal development.
Viktor Hamburger: A German-American embryologist who studied how developing limbs influence nerve growth. His experiments inspired the research that led Levi-Montalcini to nerve growth factor.
Neurotrophin: A family of proteins that regulate neuronal survival, development, and function. Nerve growth factor became the founding member of this signaling family.
World War II: A global war fought from 1939 to 1945, involving the Allied and Axis powers. Antisemitic laws and wartime conditions forced her to continue research outside formal institutions.
Neurodegeneration: The progressive loss of structure or function in neurons. Growth-factor signaling became a research avenue for understanding neuronal vulnerability and survival.
Giuseppe Levi: An Italian histologist and neuroanatomist who trained several prominent Italian scientists. He supervised Levi-Montalcini’s early research in Turin.
Trophic factor: A molecule that supports the growth, survival, or maintenance of cells. The concept of nerve growth factor helped establish trophic signaling in biology.
