| Outline of Final Research Achievements |
Equine major histocompatibility complex (MHC) class I act as receptor molecules that play an important role in EHV-1 entry into equine cells. In this study, transgenic (Tg) mice expressing equine MHC class I were generated to explore whether the ubiquitous expression of equine MHC class I rendered mice more susceptible to EHV-1 infection and then developed more severe disease conditions. Tg mice were inoculated intranasally with EHV-1, euthanized, and subjected to pathological analyses. Tg mice developed more severe bronchointerstitial pneumonia than wild-type (WT) littermate mice. The number of virus antigen-positive cells distributed within lung tissues was higher in Tg mice than that in WT mice. These results suggest that exogenous expression of equine MHC class I may increase susceptibility of lung tissues to EHV-1 infection in Tg mouse. Tg mice having equine MHC class I expression in T cells, which are one of the major target of EHV-1, are also generated.
