A2A adenosine receptor

The A2A adenosine receptor is a specialized protein found on certain cells in the body, especially in the brain and immune system. It acts like a lock that activation molecules (like adenosine) can open, triggering specific responses. When adenosine binds to A2A receptors, it usually helps reduce inflammation, promote relaxation, and regulate blood flow. These receptors play important roles in balancing immune responses and brain activity. Because of their functions, they are being studied for potential treatments for conditions like Parkinson’s disease, inflammation, and certain cancers.
