Abstract:
Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by chronic synovitis and skeletal joint deformities, often accompanied by systemic symptoms. Over the past few decades, various susceptibility factors for RA have been revealed, and numerous therapeutic drugs have been developed, including analgesics, glucocorticoids, non-steroidal anti-inflammatory drugs (NSAIDs), disease-modifying antirheumatic drugs (DMARDs), and biological agents (bDMARDs). Despite the availability of multiple treatment options, the therapeutic outcomes for some patients remain suboptimal due to the complex pathogenesis of RA. As a key pathological mechanism, programmed cell death (PCD) in RA has received extensive attention. Dysregulation of PCD in RA impacts the progression of the disease. This article systematically reviews the roles of various cell death modalities, including apoptosis, necroptosis, ferroptosis, pyroptosis, and autophagy in the pathophysiology of RA, aiming to provide a theoretical basis and direction for the discovery of new therapeutic targets and drug development.
Insights
Rheumatoid arthritis (RA) involves complex cell death pathways. Understanding programmed cell death (PCD) in RA offers new therapeutic targets for better patient outcomes.
Area of Science:
- Immunology
- Pathology
- Rheumatology
Background:
- Rheumatoid arthritis (RA) is a chronic inflammatory joint disease with complex pathogenesis.
- Despite available treatments like NSAIDs, DMARDs, and bDMARDs, suboptimal outcomes persist for some RA patients.
- Programmed cell death (PCD) is increasingly recognized as a critical factor in RA pathophysiology.
Purpose of the Study:
- To systematically review the roles of diverse cell death modalities in rheumatoid arthritis.
- To explore how dysregulated PCD contributes to RA progression and joint damage.
- To identify potential new therapeutic targets and inform drug development for RA.
Main Methods:
- Literature review of programmed cell death (PCD) in rheumatoid arthritis (RA).
- Analysis of various cell death pathways: apoptosis, necroptosis, ferroptosis, pyroptosis, and autophagy.
- Synthesis of current understanding of PCD's impact on RA pathogenesis.
Main Results:
- Dysregulation of multiple PCD pathways, including apoptosis, necroptosis, ferroptosis, pyroptosis, and autophagy, is implicated in RA.
- These cell death modalities significantly influence the chronic synovitis and joint deformities characteristic of RA.
- Understanding these mechanisms provides insights into RA's complex pathophysiology.
Conclusions:
- Targeting specific programmed cell death (PCD) pathways presents a promising strategy for novel RA therapies.
- Further research into the interplay of different cell death modalities in RA is warranted.
- This review provides a foundation for developing more effective treatments for rheumatoid arthritis.
