摘要

The footpad skin and the lumbosacral dorsal root ganglia were removed from inbred guinea pigs at different times after subcutaneous infection with herpes simplex virus type 2 (HSV-2) in both hind footpads. These tissues, shown by our previous study to harbor latent HSV, were dispersed into single cells. The presence of virus-specific thymidine kinase (TK) in these cells was assayed by the uptake and phosphorylation of [125I]deoxycytidine in culture. [125I]deoxycytidine was shown to be a specific substrate for the HSV-coded TK. The method could detect herpes TK activity in a culture of 10(6) cells with less than 0.1% of the cells being virally infected. The enzyme was readily detected in footpad cells of acutely (24 h) but not of latently (14 days to 1 year) infected guinea pigs. No herpes TK was found either in the sensory ganglionic cells of guinea pigs during the early and late phases of latent infection. It is concluded that HSV-2, while residing in the footpads and the lumbosacral ganglia of the guinea pig during latent infection, does not express any viral TK function.
