In this study, we focused on CD4 + Th cells, however, the importance of CD8 + T cells in the immunopathology of pSS has been indicated previously in pSS patients and Sjögren‐like disease models.30, 31, 32, 33 In this respect, the interplay between CCR9 + Th cells and (CCR9+) CD8 T cells has been demonstrated previously to play a key role in immunopathology.13 Subsets of CD8 T cells have been associated with clinical activity of pSS.34 In the current study, we did not study CCR9‐expressing CD8 T cells and CD8 subsets. Here, CCR9 is linked to peeling skin syndrome.
