| Research Abstract |
Elevated concentrations of free fatty acids (FFAs) such as palmitate (Pal) are implicated in the mechanism underlying obesity-associated inflammation and apoptosis. The clinical significance of FFAs in patients with primary Sjogren's syndrome (pSS), which is an autoimmune disease characterized by destruction of salivary gland epithelial cells, is little studied, even though there is evidence linking sicca syndrome with dyslipidemia and diabetes. Here, we show that Pal induces IL-6 production, alpha-fodrin degradation which is an important auto-antigen in pSS, and apoptosis in salivary gland epithelial cell, but not in other types of epithelial cells. These results suggest that Pal may exacerbate the pathogenesis of pSS in salivary glands.
