| Outline of Final Research Achievements |
Bell’s palsy is highly associated with diabetes mellitus (DM). Diabetes mellitus was induced with streptozotocin injection in only mice that developed transient facial nerve paralysis with HSV-1. Recurrent facial palsy was induced after HSV-1 reactivation by auricular scratch. After DM induction, the number of CD3+ T cells decreased by 70% in the DM mice, and facial nerve palsy recurred in 13% of the DM mice. HSV-1 DNA was detected in the facial nerve of all of the DM mice with palsy, and HSV-1 capsids were found in the geniculate ganglion using electron microscopy. These results suggested that HSV-1 reactivation in the geniculate ganglion may be the main causative factor of the increased incidence of facial paralysis in DM patients.
