Nerve Growth Factors: A primer

In honor of Brain Awareness Week, I am writing about a topic I studied during my PhD in Neuroscience: growth factors, specifically nerve growth factors, also called “neurotrophins.” These are small proteins that help neurons to survive and make connections with each other. They do so by being made in one cell and binding to a protein called a receptor on the surface of another cell. Once the neurotrophin binds to its receptor, biochemical signals are activated inside the receiving cell that enable it to survive and grow. Continue reading Nerve Growth Factors: A primer
