Wang et al. collected PBMCs from patients with SS as well as healthy controls and found relative upregulation of lncRNA TMEVPG1, proportion of Th1 cells, and IFN-γ and T-box expressed in T cells in SS CD4+ cells; TMEVPG1 also had correlations with anti-Ro/SS-A antibody, erythrocyte sedimentation rate (ESR), and IgG levels. This evidence concerns the gene IFNG and synovial sarcoma.
