In the ductal epithelium adjacent to lymphoid infiltrates and in lymphocytes of salivary glands in patients with Sjögren syndrome (SS), there is an increased expression of monokine induced by interferon (IFN)-γ(MIG) and chemokine (C-X-C motif) receptor 3 (CXCR)3, which therefore seems to participate in the SS pathogenesis.
