The expression of BTLA in liver tissues from HBV-related acute-on-chronic liver failure (HBV-ACLF) patients, as detected by immunohistochemistry. (A) BTLA expression was absent in normal liver sections; (B) BTLA expression was absent in liver sections from CHB; (C) strong BTLA staining was observed in benign bile ducts sections from HBV-ACLF patients; (D) strong BTLA staining was observed on infiltrating lymphocytes of sections from HBV-ACLF patients. The arrows indicate infiltrating positive cells, arrowhead indicated the capillaries. The scale bar indicates 20 μm.
