Director Barbara Bernardini has a profound passion for science and science communication. Holding a PhD in molecular medicine herself, she founded a company dedicated to making scientific research accessible to a broader audience. In The Brain Keepers, she tells the extraordinary story of nerve growth factor (NGF), the molecule discovered by Nobel laureate Rita Levi-Montalcini, and how it is revolutionizing neuroscience through its ability to promote nerve regeneration. From the adventurous tale of its discovery to its first applications in humans—leading to a life-changing treatment for a previously untreatable and devastating eye disease—to groundbreaking clinical trials poised to transform the treatment of major neurodegenerative disorders such as Alzheimer’s and Parkinson’s.
