Fig. 4From: Elevated expression of Toll-like receptor 7 and its correlation with clinical features in patients with primary Sjögren’s syndromeCorrelations between TLR7 expression and IgG and serum globulin. A TLR7 expression was positively associated with IgG. B TLR7 expression was positively associated with serum globulin. C TLR7 expression was positively associated with IgA. D The staining intensity of TLR7 was positively correlated with the FS of pSS. IgG, immunoglobulin G; IgA, immunoglobulin A; IgM, immunoglobulin M; FS, focus scoreBack to article page
