The autopsy showed that HSV-1 DNA, CD8+T lymphocytes, cytokines, and chemokines were present in two-thirds of human vestibular ganglia (30), and injection of HSV-1 into a mouse model resulted in vestibular dysfunction of infected vestibular ganglion cells, such as vestibular neuritis (9, 30). This evidence concerns the gene CD8A and vestibular neuronitis.
