Summary
Embryonic rat dorsal root ganglion neurons were cultured in a two-chamber system allowing infection of neuritic extensions without exposure of neuronal cell bodies or vice versa. Herpes simplex virus type 1 was used to infect interferon-α and -β treated or untreated neurons and the production of virus and interferon was assayed.
Treatment of nerve cell bodies with interferon inhibited virus replication in a dose-dependent manner, whether virus was inoculated directly onto the nerve bodies or peripherally on the neuritic extensions. In contrast no antiviral effect was noted when neurites were treated with interferon suggesting possible lack of interferon receptors on neurites. On infection with herpes simplex virus the rat sensory neuron cultures did not produce interferon in amounts above the detection limit (0.5 units per ml) of the interferon assay used.
