FIG. 4.

Localization of viral antigen and the virus-induced cellular infiltrate of phenotypically distinct populations of leukocytes in the superior colliculus after injection of PRV Becker into the vitreous body of the eye. The micrographs are of adjacent sections of tissue from a representative animal with numerous infected neurons in the superior colliculus and illustrate viral immunoreactivity (A), immunoreactivity of cells expressing the CD45 antigen (B), ED-1⁺ immunoreactive cells (C), and immunoreactive CD8β⁺ leukocytes (D). Scale bar, 100 μm for all figures.
