Effect of neurotrophic factor (NTF) deprivation on HSV reactivation in adult SCG neurons. Nerve growth factor (NGF) and glial cell line-derived neurotrophic factor (GDNF) deprivation induced reactivation of HSV1, but not HSV2, shown by significantly increased viral DNA copies 24 h after removal of individual NTFs and addition of their respective neutralizing antibodies after 7 days of acyclovir (ACV)-induced latency, compared to control neurons maintained in all three neurotrophic factors (p = 0.005 and 0.01).
