Abstract:
Synovial cells play a key role in joint destruction during chronic inflammation. In particular, activated synovial fibroblasts (SFs) undergo intrinsic alterations leading to an aggressive phenotype mediating cartilage destruction and bone erosion in rheumatoid arthritis (RA). Recent research has revealed a number of targets to control arthritogenic changes in SFs. Therefore, identification of SF phenotypes, control of epigenetic changes, modulation of cellular functions, or regulation of the activity of cation channels and different signaling pathways has been investigated. Although many of these approaches have shown efficacy in vitro and in animal models of RA, further research is needed to select the most relevant targets for drug development. This review is focused on the role of SFs as a potential strategy to discover novel therapeutic targets in RA aimed at preserving joint architecture and function.
Insights
Activated synovial fibroblasts drive joint destruction in rheumatoid arthritis (RA). Targeting these cells offers a promising strategy for novel RA therapeutics to preserve joint function.
Area of Science:
- Rheumatology
- Cell Biology
- Immunology
Background:
- Synovial fibroblasts (SFs) are key drivers of joint destruction in chronic inflammatory conditions.
- Activated SFs in rheumatoid arthritis (RA) adopt an aggressive phenotype, causing cartilage degradation and bone erosion.
Purpose of the Study:
- To review the role of SFs in RA pathogenesis.
- To explore SFs as a therapeutic target for preserving joint architecture and function in RA.
Main Methods:
- Literature review of recent research on SFs in RA.
- Analysis of potential therapeutic strategies targeting SF phenotypes, epigenetic changes, cellular functions, and signaling pathways.
Main Results:
- Various approaches targeting SFs have shown efficacy in preclinical models.
- Identification and modulation of SF phenotypes are crucial for controlling arthritogenic changes.
- Regulation of cation channels and signaling pathways in SFs are potential therapeutic avenues.
Conclusions:
- SFs represent a significant therapeutic target for developing novel RA treatments.
- Further research is necessary to identify the most effective targets for drug development to preserve joint integrity in RA.
