FIG. 1.

Expression of GFP from an adenovirus vector in TG cell cultures latently infected with HSV-1. (A and B) Representative photomicrographs of a neuron in a latently infected TG cell culture 72 h after superinfection with 40 PFU of Ad.C-GFP/cell, as seen when illuminated with visible light (A) or the 360- to 400-nm spectrum of light, which excites GFP fluorescence (B). Magnification, ×40. (C) Frequency of HSV-1 reactivation in latently infected TG cell cultures superinfected with 20 or 100 PFU of Ad.C-GFP/cell, with or without heat stress (HS) (n = 12 per group). ACV off, point at which ACV was removed from culture.
