From: CD64 as novel molecular imaging marker for the characterization of synovitis in rheumatoid arthritis
CD64 expression correlates with immune cell infiltration in RA synovium. A Examples of fluorescence imaging (Odyssey) of DRAQ5 (nuclei), CD64 (cell membrane), or isotype (on a consecutive section) and merged images from 3 patients. B CD64 expression was measured using immunofluorescence. C Expression of CD64 correlates with the extent of immune cell infiltration measured with an arbitrary score in the same tissue section. The scatter plot depicts mean ± SEM (B) and each data point in the XY graph represents a value of 1 patient (C). n = 21 late RA patients, rs = Spearman’s rank correlation coefficient, ***p ≤ 0.001
