Fig 6. B cells in the IRF8 deficient mice are hypersensitive to antigen stimulation.
A) B cells were isolated from spleens of IRF8+/+HEL-Tg and IRF8−/−HEL-Tg mice, stained with CFSE dye and incubated with increasing concentrations of HEL. Four days later, the cells were analyzed by FACS. B) The isolated B cells from IRF8+/+HEL-Tg and IRF8−/−HEL-Tg mice were treated with increasing concentrations of HEL. The treated cells were lysed after 12h. Western Blot analysis was used to detect the expression of c-Myc, cyclin D2 and IRF4. The results are representatives of at least three independent experiments.
