Continuous IFN-γ infusion effects on T-cell expansion and activation. CD4 and CD8 T cells in the BM of recipient mice, as described in Figure 5, were measured by flow cytometry, shown as percentages in representative dotplots, and was calculated as total cells per animal, shown as means with SEs (A). Proportion and total number of CD8 T cells that expressed the inflammatory cytokine IFN-γ are also shown as representatives and means with SEs (B). T-cell activation was assessed by CD11a expression, shown in the same fashion (C).
