Activation of Peptidylarginine Deiminase in the Salivary Glands of Balb/c Mice Drives the Citrullination of Ro and La Ribonucleoproteins

Figure 6

Double fluorescence assays showing colocalization. Graphs show the fluorescent expression of Ro60 and La ribonucleoproteins in response to different molecular triggers. A representative double fluorescence assay of Ro and La (green) colocalization with citrullinated proteins (red). Nuclei are counterstained with DAPI (blue). The green and red fluorescence was analyzed in specific areas of colocation indicated by arrows and magnified in boxes, and the colocalization was analyzed by a regression analysis, which resulted with r2 of 0.674 for Ro60 meanwile 0.295 for La ribonucleoprotein. The asterisk on the top bars means significant differences from control (, Student t-test).
