The aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor that is involved in the regulation of many physiological processes, including the immune response, cell differentiation, and xenobiotic metabolism. It is activated by a variety of small molecules, including environmental pollutants such as dioxins, polycyclic aromatic hydrocarbons (PAHs), and polychlorinated biphenyls(PCBs).
