AhR (Aryl hydrocarbon receptor)

The Aryl Hydrocarbon Receptor (AhR) is a protein inside cells that acts as a sensor for certain chemicals, especially those from pollution or plant compounds. When it detects these substances, AhR moves into the cell nucleus and influences gene activity, helping the body respond to environmental chemicals. This process can impact how the body detoxifies, how immune responses develop, and even influence cell growth. While AhR plays a role in protecting us from harmful substances, its activation by certain pollutants can also contribute to health issues like inflammation or cancer if triggered excessively.
