Figure 4.

Immunohistochemical detection of VZV E proteins in human DRG. DRG harboring latent (A) or reactivated (B) virus and a control fetal DRG (C) were analyzed. The products of ORFs 21 and 29 were detected as described in the legend to Fig. 1. The specimens used are shown at the top, and the individual genes whose products were analyzed are shown on the left. The arrows indicate neurons with positive nuclei. The staining seen near the plasma membrane of some neurons is from coloration of lipofuschin.
