TrkB receptor

The TrkB receptor is a specialized protein found on nerve cells that acts like a lock, activating when it binds to a specific molecule called brain-derived neurotrophic factor (BDNF). This activation helps support the growth, survival, and functioning of neurons—the cells responsible for transmitting information in the brain and nervous system. In essence, TrkB helps brain cells stay healthy, adapt, and form new connections, which is important for learning, memory, and mood regulation. It plays a key role in neural development and maintaining healthy brain function throughout life.
