Protective effects of rat splenic lymphocytes and peritoneal exudate cells on herpes simplex virus infection of rat dorsal root ganglia in culture.
An in vitro model system was developed to study the effects that immune cells might have on herpes simplex virus (HSV) infection of rat dorsal root ganglia in culture. Our results demonstrate that rat splenic lymphocytes and peritoneal exudate cells are incapable of replicating HSV even if these cells come from sensitized animals and are stimulated in vitro. Both cell preparations can offer some protection to rat dorsal root ganglia from the effects of HSV infection. The data suggest that an immunologically non-specific (not mediated by sensitized cells) type of protection is important to neurons, while an immunologically specific (mediated by sensitized cells) protection is most beneficial to fibroblasts. This system can be utilized to study the mechanism of latency since the neurons of sensory ganglia are the natural site of latent herpes virus.
