A2A receptor

The A2A receptor is a protein found on the surface of certain cells, especially in the brain and immune system. It acts like a switch that responds to a molecule called adenosine, which is involved in regulating blood flow, immune responses, and brain activity. When adenosine binds to the A2A receptor, it triggers specific signals inside the cell, helping to reduce inflammation, promote relaxation, and modulate neural activity. This receptor is significant because it influences how the body responds to stress, fatigue, and neurological conditions like Parkinson’s disease.
