Figure 6

MAP-TB vaccination enhanced the formation of GCs in the spleen sections of immunized mice stained by PNA (green) and B220 (orange). The scale bar represents 1000 μm. The areas of GCs were normalized by section area, and spleen sections of three mice from each group were analyzed by ImageJ software (d).
