Interleukin‐7/Interferon Axis Drives T Cell and Salivary Gland Epithelial Cell Interactions in Sjögren’s Syndrome

These results suggest the presence of an IL-7/IFNγ amplification loop involving SGECs and T cells in primary SS. IL-7 was secreted by SGECs stimulated with type I or type II IFN and, in turn, activated T cells that secrete type II IFN. An anti-IL-7R antibody decreased the IFN signature in T cells in primary SS and could be of therapeutic interest.
