In our study, the differently expressed proteins among the patients with AIH and controls (GAS 6, FCGR2A, CXCL10, CCL19, CA1, CA3 and 4E-BP1) are described in multiple liver diseases with proteomic analysis that uses different technologies, such as two-dimensional gel electrophoresis (2-DE), image analysis and mass spectrometry (MS). The gene discussed is CCL19; the disease is liver disorder.
