Expression of ICOS and ICOSL by lymphocytes and monocyte-derived macrophages (MoMFs) infiltrating the liver during acute inflammation. Liver inflammation was induced in response to acute hepatocyte injury caused by carbon tetrachloride (CCl4) in wild-type mice. The expression of ICOS was evaluated by flow cytometry in CD3+ T-lymphocytes infiltrating the liver of control (Cont) and CCl4-treated mice following 24 or 72 hours after challenge with the toxic agent (A). Characterization of ICOS-expressing CD3+/CD4+ helper and CD3+/CD8+ cytotoxic T-cells in the liver of mice receiving CCl4 for 72 hours (B). Flow cytometry analysis of ICOSL expression among CD11b+/F4-80+ MoMFs (C). The values are expressed as mean ± SD of 3-4 different cell preparations.
