aryl hydrocarbon receptor

The aryl hydrocarbon receptor (AhR) is a protein inside our cells that helps detect certain chemicals, especially environmental pollutants like dioxins and some plant compounds. When these chemicals bind to AhR, it activates the receptor, leading to the process of turning specific genes on or off. This influences how the body responds to pollutants, affects immune function, and can impact cell growth. In essence, AhR acts as a molecular sensor, helping the body manage exposure to external substances and maintain internal balance.
