| Outline of Final Research Achievements |
We determined the median spot numbers and examined varicella zoster virus (VZV)-specific cell-mediated immunity (CMI) in patients with Hunt syndrome and with Bell's palsy using IFN-γ enzyme-linked immunospot (ELISPOT) assays. We analyzed the relationship between the value of VZV-specific CMI and days from disease onset. The median spot number in Hunt syndrome (87.3) was higher than that in Bell's palsy (62.3). Hunt syndrome showed a strong relationship between the ELISPOT count and days from onset. Within the first 5 days from onset, no ELISPOT counts higher than 80 were observed. These results suggest that VZV-specific CMI in Hunt syndrome is low at disease onset and increases rapidly thereafter. Consequently, reduced VZV-specific CMI may play an important role in the reactivation of VZV in the facial nerve, leading to Hunt syndrome
