The Role of the Aryl Hydrocarbon Receptor (AhR) in the Immune Response against Microbial Infections

Abstract

Aryl hydrocarbon receptor (AhR), an important nuclear receptor, regulates the cellular response to environmental stressors. It is well known for its critical functions in toxicology, but is currently considered an essential regulator of diseases, with specific modulatory effects on immune, antimicrobial and inflammatory responses. The present chapter discusses AhR’s function and mechanism in the immune response against microbial infections.
