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.

About CCL21

This antimicrobial gene is one of several CC cytokine genes clustered on the p-arm of chromosome 9. Cytokines are a family of secreted proteins involved in immunoregulatory and inflammatory processes. The CC cytokines are proteins characterized by two adjacent cysteines. Similar to other chemokines the protein encoded by this gene inhibits hemopoiesis and stimulates chemotaxis. This protein is chemotactic in vitro for thymocytes and activated T cells, but not for B cells, macrophages, or neutrophils. The cytokine encoded by this gene may also play a role in mediating homing of lymphocytes to secondary lymphoid organs. It is a high affinity functional ligand for chemokine receptor 7 that is expressed on T and B lymphocytes and a known receptor for another member of the cytokine family (small inducible cytokine A19).
