Figure 6.
TLR9−/− mice exhibit decreased LN hypertrophy following L. major infection. C57BL/6 (B6) or TLR9−/− mice were infected with L. major or injected with killed L. major antigen and the cellularity of the dLN assessed on day 3 (A). Conventional or germ-free C57BL/6 mice were infected with L. major, and the cellularity of the dLN assessed on day 3 (B). The results expressed are the mean (+/− SE) number of cells in the dLN of 3 mice per group. The results are representative of 2 experiments.
