D2 receptor

The D2 receptor is a type of protein found in the brain that responds to dopamine, a chemical involved in feelings of pleasure, motivation, and movement. It acts like a lock that dopamine (the key) fits into, helping transmit signals between neurons. D2 receptors play an important role in regulating mood, behavior, and coordination. They are also involved in medical conditions like schizophrenia and Parkinson’s disease, and are targeted by certain medications to help manage symptoms. Understanding D2 receptors helps researchers develop drugs to treat mental health and neurological disorders effectively.
