The role of imbalanced CD226/TIGIT on activated peripheral double-negative T cells in the pathogenesis of primary Sjögren's syndrome

To explore whether the balance of CD226 and TIGIT is disturbed in CD3+CD56-TCRαβ+CD4-CD8- (DN) T cells and have a better understanding of the potential role of DN T cells in the pathogenesis of primary Sjögren's syndrome (pSS).
