Compared to control mice, CXCL10 serum level increased in PBC mice and the proportion of CXCR3+ cells increased in the intrahepatic infiltrates of PBC mice, chiefly on CD8+ cells, whereas the expression of CXCR3 on CD3+ and CD8+ splenocytes decreased in PBC model. The gene discussed is CXCL10; the disease is primary biliary cholangitis.
