Ferroptosis in inflammatory arthritis: A promising future

Area of Science:

• Biomedical Science
• Cellular Biology
• Immunology

Background:

• Ferroptosis is a regulated form of cell death driven by iron accumulation and lipid peroxidation.
• It involves distinct mitochondrial changes and a complex regulatory network.
• Emerging evidence highlights ferroptosis's role in the pathogenesis of inflammatory arthritis.

Purpose of the Study:

• To review and summarize research on ferroptosis in various inflammatory arthritides.
• To specifically examine the relationship between rheumatoid arthritis (RA) and ferroptosis.
• To explore potential therapeutic avenues targeting ferroptosis in inflammatory arthritis.

Main Methods:

• Literature review of studies on ferroptosis in rheumatoid arthritis, osteoarthritis, gout arthritis, and ankylosing spondylitis.
• Analysis of evidence for iron overload, lipid peroxidation, and mitochondrial dysfunction in RA patients and models.
• Examination of the ferroptosis-modulating effects of existing anti-rheumatic drugs.

Main Results:

• Studies indicate iron overload, lipid peroxidation, and mitochondrial dysfunction in RA patients and animal models, suggesting ferroptosis involvement.
• Ferroptosis inducers show promise in cancer therapy.
• Established anti-rheumatic drugs like methotrexate and sulfasalazine demonstrate ferroptosis-modulating capabilities.

Conclusions:

• Ferroptosis plays a significant role in the pathogenesis of inflammatory arthritis and warrants further investigation.
• Targeting ferroptosis presents a promising therapeutic strategy for inflammatory arthritis patients.
• The interplay between ferroptosis and inflammatory arthritis requires deeper understanding for effective treatment development.
