Fig 3. Few infiltrations of pDCs in labial gland and theclinical correlation analysis. a: Immunofluorescent results of 4 pSS patients who had labial pathological report with typical focal lymphocytic infiltrations.b: Immunofluorescent colocalization of epithelial cells (CD326) and IFN-α in salivary glands of pSS patients (n=2). c:Comparison of surface chemotactic receptors (MFI) in pDCs between pSS and HCs, CCR2 (HC: n=11; pSS: n=11), CCR4 (HC: n=11; pSS: n=10), CCR5 (HC: n=12; pSS: n=12), CCR7 (HC: n=10; pSS: n=12), CCR10 (HC: n=14; pSS: n=12). d: Correlation analysis of pDC percentage in PBMC and serum IgG (n=30), IgA (n=29), anti-SSA IgG (n=23). Data are shown as mean ± SEM. Unpaired two-tailed Student’s t-test, Linear regression and Pearson’s correlation were performed for IgG and IgA, Spearman rank correlation were performed for anti-SSA IgG.
