FIG 6.

Colonization of BAFF-R^−/− splenic follicles by eGFP⁺ MuHV-4. We infected BAFF-R^−/− mice i.p. with eGFP⁺ MuHV-4 as for Fig. 5 and 4 or 8 days later stained splenic sections for eGFP (green) plus IgM (red) and, as a further cell type marker, either B220, MARCO, IgD, or CD169 (white). Nuclei were counter-stained with DAPI (blue). The boxed regions of the left-hand overviews (scale bars shows 100 μm) are shown at higher power in the right-hand zoomed images, with either merged or individual channels. Arrows show examples of eGFP⁺ cells.
