English: HBV replication-competent transgenic mice were injected with Clo-L and 3 days later subjected to liver intravital microscopy. The movie depicts lobular liver sinusoids in a representative mouse that was infused 5 minutes earlier with 5×107 CFSE-labeled HBV-specific effector CD8 T cells (green). Analysis of movies derived from six independent HBV replication-competent transgenic mice revealed a sticking fraction (defined as the percentage of total CD8 T cells that became firmly adherent for ≥30 s while passing a liver sinusoid within a 30 minutes observation period) of 27.1%±1.9%. Scale bar represents 50 µm.
