hus, 4-week-old B6 mice were inoculated i.p. with rLm-gp33 or, as a control, with rLm-np118 (rLm expressing an LCMV nucleocapsid epitope np118-126) (29). Two weeks later, mice were infected with either RA59gfp/gp33 or, as a control, RA59-gfp. At day 5, the peak of virus replication in the CNS, mice were sacrificed and the brains, livers, and spleens were harvested.
liver
The brains and livers were titrated for virus, and spleens were used for quantification of CD8+ T cells specific for gp33 and the MHV spike CD8+ T-cell epitope S598
