Understanding cytokine pathways, particularly those targeting TNF, is crucial for understanding pathology and advancing treatment development. Arid5a is a noncanonical RNA binding protein (RBP) that augments inflammation through stabilizing proinflammatory mRNAs and enhancing protein translation. We examined published datasets for\n                    <jats:italic>ARID5A<\/jats:italic>\n                    in human RA blood, T cells, and synovial tissues. A stromal cell line, epithelial cells, and primary synovial fibroblasts were used to assess the effect of TNF on Arid5a expression, localization, and function. To determine how TNF induces Arid5a, WT or\n                    <jats:italic>\n                      Traf2\n                      <jats:sup>\u2013\/\u2013<\/jats:sup>\n                    <\/jats:italic>\n                    stromal cells were treated with NIK or IKK inhibitors. To evaluate the necessity of Arid5a in arthritis progression,\n                    <jats:italic>\n                      Arid5a\n                      <jats:sup>\u2013\/\u2013<\/jats:sup>\n                    <\/jats:italic>\n                    mice were subjected to collagen-induced arthritis.\n                    <jats:italic>ARID5A<\/jats:italic>\n                    was elevated in patients with RA and reduced by anti-TNF therapy. TNF upregulated Arid5a through the NF-\u03baB1\/TRAF2 pathway, causing cytoplasmic relocalization. Arid5a stabilized proinflammatory transcripts and enhanced expression of chemokines that drive RA.\n                    <jats:italic>\n                      Arid5a\n                      <jats:sup>\u2013\/\u2013<\/jats:sup>\n                    <\/jats:italic>\n                    mice were resistant to collagen-induced arthritis correlating with reduced Th17 cells in synovial tissue. Thus, Arid5a serves as a newly recognized signaling intermediate downstream of TNF that is elevated in human RA and drives pathology in murine CIA, potentially positioning this RBP as a possible therapeutic target.\n
