Pyroptosis and its role in autoimmune skin disease

Area of Science:

• Immunology
• Dermatology
• Cell Biology

Background:

• Autoimmune skin diseases involve complex interactions of genetic, infectious, environmental, and psychological factors.
• Abnormal innate and adaptive immune responses characterize these conditions, with unclear exact mechanisms.
• Emerging evidence highlights pyroptosis as a key player in the pathogenesis of autoimmune skin diseases.

Purpose of the Study:

• To review the molecular mechanisms of pyroptosis, including NLRP3 inflammasome and gasdermin family regulation.
• To summarize the role of pyroptosis in specific autoimmune skin diseases such as systemic lupus erythematosus, psoriasis, atopic dermatitis, and systemic scleroderma.
• To explore the potential of pyroptosis as a therapeutic target and prognostic biomarker for autoimmune skin diseases.

Main Methods:

• Review of current literature on pyroptosis and autoimmune skin diseases.
• Analysis of molecular mechanisms of pyroptosis, focusing on inflammasome pathways.
• Synthesis of recent findings on pyroptosis in systemic lupus erythematosus, psoriasis, atopic dermatitis, and systemic scleroderma.

Main Results:

• Pyroptosis involves cell membrane pore formation, rupture, and release of pro-inflammatory cytokines (e.g., IL-1β, IL-18).
• This programmed cell death disrupts immune homeostasis and promotes autoimmunity.
• Pyroptosis is implicated in the pathogenesis of various autoimmune skin conditions.

Conclusions:

• Understanding pyroptosis mechanisms provides insights into autoimmune skin disease development.
• Targeting pyroptosis presents a promising therapeutic strategy for autoimmune skin diseases.
• Pyroptosis biomarkers may aid in disease prognosis and management.
