FIG. 10.

Virus-induced recruitment of immune cells into the brain is increased in PRV 326-infected animals. The extent of ED1+ immune cell recruitment into the dorsal motor vagal complex 72 h after infection with PRV Bartha (A) or PRV 326 (B) is illustrated. Note the larger number of immunopositive cells within the DMV and immediately adjacent nucleus of the solitary tract (nts) of PRV 326-infected animals. The area postrema (AP) is indicated. The yellow area in the schematic inset illustrates the location of the area illustrated in the photomicrographs. The magnification of both images is the same. Bar = 100 μm.
