Summary
Epigenetic alterations, including DNA methylation and histone modifications in the immune system and synovial fibroblasts, are implicated in rheumatoid arthritis pathogenesis. Future epigenetic therapies are being explored to target these changes.
Area of Science:
- Immunology
- Molecular Biology
- Rheumatology
Background:
- Rheumatoid arthritis (RA) is an autoimmune disease characterized by chronic inflammation.
- Epigenetic modifications play a crucial role in regulating gene expression without altering DNA sequence.
Purpose of the Study:
- To review current understanding of epigenetic changes in rheumatoid arthritis.
- To highlight the role of DNA methylation and histone modifications in RA pathogenesis.
- To discuss the contribution of synovial fibroblasts to RA autoimmunity.
Main Methods:
- Review of existing literature on epigenetics in rheumatoid arthritis.
- Analysis of DNA methylation and histone modification patterns in immune cells and synovial fibroblasts.
- Discussion of the functional implications of these epigenetic changes.
Main Results:
- Deregulation of DNA methylation and histone modifications are observed in the immune system contributing to RA.
- Synovial fibroblasts exhibit specific epigenetic alterations during the disease process.
- These epigenetic changes in synovial fibroblasts are linked to autoimmune responses in RA.
Conclusions:
- Epigenetic dysregulation is a key feature of rheumatoid arthritis.
- Epigenetic modifications in immune cells and synovial fibroblasts offer potential therapeutic targets.
- Further research is needed to fully elucidate epigenetic mechanisms and develop effective epigenetic therapies for RA.

Genome-wide Association Studies-GWAS
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.

Epigenetic Regulation
Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.
Epigenetic Regulation
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

T Cell Types and Functions
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.

The JAK-STAT Signaling Pathway
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...
