Correlations 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.
