A1 receptor

The A1 receptor is a protein found on certain cells in the body that responds to a molecule called adenosine. When adenosine binds to the A1 receptor, it helps slow down cellular activity, which can promote feelings of relaxation, reduce pain, and help protect tissues during stress. These receptors are involved in regulating heart rate, nerve activity, and blood flow. They play a key role in maintaining balance in the body's systems by modulating how cells communicate and respond to signals, especially during times of rest or recovery.
