Similar to earlier report in mouse, we observed an increased co-localization (indicated with arrowheads in magnified images) of cytokeratin (marker for mesothelium) and CX3CL1 from 0.1% NaClO-injured pigs demonstrated NaClO-induced overexpression of fractalkine CX3CL1 in both parietal and visceral mesothelium indicated that NaClO-induced PF and PD-induced PF may at least in part, share similar signal transduction pathway. The gene discussed is CX3CL1; the disease is pemphigus foliaceus.
