Herpes virus genes, like their genes eukaryotic host, are not arranged in operons and in most cases have separate promoters. Unlike eukaryotic genes, however, few herpesvirus genes are spliced. These genes were characterized as being required or dispensable for growth in cell culture.

How are herpes viruses classified?

Herpesviruses are divided into three groups: Alpha herpesviruses: Herpes simplex virus types 1 and 2and varicella-zoster virus, which have a short replication cycle, induce cytopathology in monolayer cell cultures, and have a broad host range.

Previous research has linked a protein called JNK to stress.The team already knew that HSV was dormant in neurons, and Stress triggers virus reactivation. Corticosteroids are natural stress hormones that have been shown to activate the JNK pathway and trigger neuronal death.

How does the herpes virus hide?
