Nucleic Acid Sensor-Mediated PANoptosis in Viral Infection

Area of Science:

• Immunology
• Virology
• Cell Biology

Background:

• Innate immunity is crucial for host defense against viral infections.
• Pattern-recognition receptors, including nucleic acid sensors, detect viral components.
• Viral nucleic acids are primarily sensed by Toll-like receptors, NOD-like receptors, AIM2-like receptors, and cytosolic DNA sensors.

Purpose of the Study:

• To review the structures and functions of nucleic acid sensors in viral infections.
• To discuss the role of these sensors in initiating PANoptosis, an inflammatory cell death pathway.
• To highlight the therapeutic potential of targeting nucleic acid sensors for treating viral diseases.

Main Methods:

• Literature review of studies on nucleic acid sensors and viral infections.
• Analysis of the mechanisms by which nucleic acid sensors trigger PANoptosis.
• Examination of the structural basis for specific viral recognition by different sensors.

Main Results:

• Nucleic acid sensors, such as ZBP1 and AIM2, detect viral nucleic acids and initiate PANoptosis by forming PANoptosome complexes.
• Different sensors recognize specific viruses based on their unique structures.
• Crosstalk exists between various nucleic acid sensors.

Conclusions:

• Nucleic acid sensors play a dual role in detecting viruses and mediating PANoptosis.
• Targeting nucleic acid sensors presents a promising therapeutic avenue for managing viral infections.
• Understanding sensor structures and interactions is key to developing novel antiviral strategies.
