Salivary gland and peripheral blood T helper 1 and 2 cell activity in Sjögren's syndrome compared with non-Sjögren's sicca syndrome

摘要

Objectives: To investigate whether differences in T helper (Th) 1 and Th2 cell activity in salivary glands ("local") or ("peripheral") blood can discriminate between Sjögren's syndrome (SS) and non-Sjögren's sicca syndrome (nSS-sicca). Additionally, to study relationships of local and peripheral Th cell activities with each other and with disease activity measures.
