Isolation of CCR7+/RELB+/IRF1+ triple positive T cells from JIA patients and cHC individuals confirmed a presence in JIA’s CCR7+ T cells, whereas cHC exhibited this triple positivity in subsets of CD4 Naïve and CD8 Naïve cells (Figure 2H; Supplementary Figure S2A). Here, RELB is linked to juvenile idiopathic arthritis.
