Fig. 2From: Elevated expression of Toll-like receptor 7 and its correlation with clinical features in patients with primary Sjögren’s syndromeSerum levels of IFN-a and IL-6 in patients with pSS were elevated compared with those in non-SS patients. Correlations between TLR7 expression and serum cytokines. A TLR7 expression was positively associated with IFN-α. B TLR7 expression was positively associated with IL-6. C TLR7 expression in LSGs were positively correlated with serum IFN-a in pSS. D TLR7 expression in LSGs was positively correlated with the serum level of IL-6 in pSS. **P < 0.01.
