Channelling inflammation: gasdermins in physiology and disease

Area of Science:

• Immunology
• Cell Biology
• Molecular Biology

Background:

• Gasdermins are key mediators of pyroptosis, an inflammatory form of programmed cell death.
• Pyroptosis is triggered by the cell's detection of intracellular pathogens or danger signals.
• Gasdermin activation leads to pore formation in the cell membrane, releasing inflammatory molecules.

Purpose of the Study:

• To review current knowledge on the gasdermin protein family.
• To elucidate the mechanisms of gasdermin action in normal physiology and disease.
• To highlight therapeutic strategies targeting gasdermin activity.

Main Methods:

• Literature review of gasdermin research.
• Analysis of gasdermin roles in various biological processes.
• Examination of therapeutic interventions targeting gasdermins.

Main Results:

• Gasdermins form pores that compromise cell membrane integrity.
• These pores release pro-inflammatory cytokines and alarmins, amplifying inflammation.
• Emerging roles in autoimmune diseases, infectious diseases, deafness, and cancer are identified.

Conclusions:

• Gasdermins are critical regulators of inflammatory responses and cell death.
• Modulating gasdermin activity presents promising therapeutic opportunities.
• Targeting gasdermins could reduce inflammation or enhance anti-tumor immunity.
