| Research Abstract |
IL-18 is a proinflammatory cytokine and plays an important pathogenic role in inflammatory and autoimmune disorders. IL-17 is also a proinflammatory cytokine and IL-17-secreting Th17 cells are involved in autoimmunity. The majority of the infiltrating cells in the salivary glands of SS patients were CD4^+T cells, and CD8^+T cells were infiltrated to a lesser extent. The predominant expression of IL-17 was found in infiltrating CD4^+T cells, whereas a small number of infiltrating CD8^+T cells expressed IL-17. Primary salivary gland cells from normal subjects partially confirmed these findings. These results suggest that IL-18 and Th17 cells detected in the salivary glands in SS patients are associated with the pathogenesis of SS in the salivary glands.
