Gasdermins and pyroptosis in the kidney.

Area of Science:

• Cell Biology
• Immunology
• Pathology

Background:

• Pyroptosis is a regulated cell death pathway mediated by gasdermin proteins.
• Initially linked to inflammasomes and caspase-1, gasdermins are now recognized as key effectors.
• Gasdermin activation can occur independently of inflammasomes and caspases, with crosstalk to other cell death pathways.

Purpose of the Study:

• To review the role of gasdermins and pyroptosis in various diseases.
• To explore the potential involvement of gasdermins and pyroptosis in kidney diseases.
• To highlight the limited understanding of gasdermin biology in the kidney.

Main Methods:

• Literature review of pyroptosis and gasdermin function.
• Analysis of existing evidence on pyroptosis in non-microbial diseases.
• Examination of studies related to inflammasomes, apoptosis, and kidney disease.

Main Results:

• Gasdermins mediate pyroptosis by forming membrane pores, leading to cell lysis and cytokine release.
• Pyroptosis and gasdermins are implicated in host defense, cancer, and diseases of the gut, liver, and skin.
• Evidence suggests potential roles in acute kidney injury and chronic kidney disease, but understanding is limited.

Conclusions:

• Gasdermins are central effectors of pyroptosis, a cell death pathway with diverse roles.
• While pyroptosis is important in immunity and implicated in various pathologies, its specific functions in kidney disease require further investigation.
• Further research is needed to elucidate the mechanisms and implications of gasdermin-mediated pyroptosis in renal health and disease.
