Localization of cytotoxic T cells and dendritic cells in liver biopsies. a/b Identification of cytotoxic T cells by CD8 immunohistochemistry in CH (a) and CE (b) samples. Note the significant portal and lobular presence of CD8 + T cells in CH (c) and a decreased infiltration in CE sample (b). c/d Identification of dendritic cells in liver biopsies using CD1a immunohistochemistry. Note the complete absence of CD1a + cells in CE (d) as compared to CH (c) sample. Bar: 100 μm
