Wnt signaling pathway activities may be altered in primary Sjogren’s syndrome

Serum DKK1 and sclerostin levels in primary SS and SLE were decreased. Moreover, levels of Wnt1 and Wnt3a expression in the salivary gland were also elevated in primary SS. Therefore, it can be concluded that the Wnt/β-catenin pathway activities may be altered in case of glandular inflammation.
