Reduction of CD83 Expression on B Cells and the Genetic Basis for Rheumatoid Arthritis: Comment on the Article by Thalayasingam et al
FunctionalN=16Yumi Tsuchida et al.(2018)· Arthritis &amp; Rheumatology

This functional study integrates epigenomic datasets (ATAC-seq, Hi-C, ChIP-seq, RNA-seq) from fibroblast-like synoviocytes (FLS) to map the functional relevance of 101 fine-mapped rheumatoid arthritis GWAS associations. FLS regulatory elements account for 24% of RA heritability, and the study assigns putative target genes to RA risk loci, identifying TNFAIP3, IFNAR1, CDK6, RBPJ and others as disease-relevant genes. TNF stimulation reveals dynamic chromatin interactions and differential gene expression at RA-associated regulatory regions.
