Abstract

The role of nerve growth factor (NGF) in the modulation of herpes simplex virus (HSV) latency and reactivation was investigated in a mouse model. To determine whether NGF depletion would reactivate latent virus, concentrated anti-NGF serum antibodies were administered intraperitoneally to latently infected mice for 9 consecutive days. To determine whether NGF given prophylactically could suppress UV-B-induced viral reactivation, mice were irradiated with UV-B while being treated with NGF using diverse regimes over a 4-day period. Following intraperitoneal administration of anti-NGF antibodies, viral shedding was detected in a small number (10%) of mice, but it was not possible to pharmacologically suppress UV-B-induced viral reactivation with NGF. It would appear, therefore, that HSV latency in neurons innervating the cornea can be sustained and disrupted by physiological factors independent of NGF levels.
