The role of the AHR in host-pathogen interactions

Area of Science:

• Immunology
• Microbiology
• Pharmacology

Background:

• Host-microorganism interactions vary, involving pathogens, environmental microbes, and symbiotic microbiota.
• The aryl hydrocarbon receptor (AHR), initially known for xenobiotic binding, is now recognized for its role in immunity and inflammation.
• AHR is classified as a pattern recognition receptor, sensing various microbial signals.

Purpose of the Study:

• To review the role of AHR in host-pathogen interactions.
• To explore AHR sensing of different microbial classes and involved ligands.
• To examine AHR-mediated responses, disease outcomes, and therapeutic potential in infection.

Main Methods:

• Literature review focusing on AHR's role in host-microorganism interactions.
• Analysis of studies detailing AHR sensing mechanisms and signaling pathways.
• Examination of research on AHR's impact on immune responses and disease progression.

Main Results:

• AHR actively senses a wide range of microorganisms and infectious conditions.
• AHR activation influences immune and inflammatory responses critical for controlling microbial threats.
• Different microbial classes elicit distinct AHR-mediated responses, impacting disease outcomes.

Conclusions:

• AHR is a crucial mediator in host responses to microbial challenges.
• Understanding AHR signaling provides insights into host-pathogen dynamics.
• Targeting AHR presents a promising therapeutic avenue for infectious diseases.
