Rita Levi-Montalcini
Definition
Rita Levi-Montalcini was an Italian-American scientist who made significant contributions to the fields of neuroscience and cell biology. She is best known for her discovery of nerve growth factor (NGF), a protein that plays a critical role in the development and maintenance of the nervous system.
Levi-Montalcini was born in Turin, Italy, in 1909. She studied medicine at the University of Turin, where she graduated in 1936. After graduating, she moved to the United States to continue her research.
In the United States, Levi-Montalcini worked with Stanley Cohen to discover NGF. They found that NGF is produced by cells in the body and that it helps to stimulate the growth and development of nerve cells. Levi-Montalcini's research has helped scientists to understand how the nervous system works and has led to new treatments for diseases such as Alzheimer's disease and Parkinson's disease.
Levi-Montalcini was a brilliant scientist and a role model for women in science. She was also a passionate advocate for peace and social justice. She died in 2012 at the age of 103.
Levi-Montalcini's work has had a profound impact on our understanding of the nervous system. Her discovery of NGF has led to new treatments for diseases that affect the nervous system, and her research has inspired generations of scientists. She is a true pioneer in the field of neuroscience, and her work will continue to benefit humanity for years to come.

AQA Science Exam Question and Answer
Question:
Discuss the contributions of Rita Levi-Montalcini to our understanding of nerve growth factor and its implications for biology and medicine.
Answer:
Rita Levi-Montalcini, a distinguished neurologist, made significant contributions to our comprehension of nerve growth factor (NGF) and its far-reaching implications in biology and medicine. She discovered NGF, a protein crucial for the growth, maintenance, and survival of nerve cells. Her groundbreaking experiments demonstrated that tissues release NGF to promote nerve cell growth, uncovering a fundamental mechanism in nervous system development.
Levi-Montalcini's work not only deepened our understanding of neurodevelopment, but it also illuminated potential medical applications. Her insights have been vital in studying neurodegenerative diseases like Alzheimer's and Parkinson's, where disrupted NGF signalling plays a role. Additionally, her research has led to innovative therapies, including NGF-based treatments for nerve injuries and neurodegenerative disorders.
