| Research Abstract |
We have reported that tyrosinase family protein can induce autoimmune disease similar to Vogt-Koyanagi Harada disease (VKH). The lymphocytes from PBMC with VKH disease patients proliferate against tyrosinase family proteins. These results suggest that tyrosinase family proteins are antigens specific to VKH.
In this project, we further confirmed these results and studied the immune reactions involved in VKH.To clarify the development and differentiation of autoreactive T cells in VKH, we are now making the transgenic Lewis rats expressing tyrosinase. Lewis rats lacks the tyrosinase, but are sensitive to the various kind of autoimmune disease. The Lewis rats that express tyrosinase in different organs and periods will be effective to study the central and peripheral tolerance against autoantigens.
We are planing to make the transgenic rats that will express tyrosinase under the promoter of arrestin for retina specific expression, β-actin for ubiquitous expression and tyrosinase for melanocyte. We are now making the siblings of the rats bearing the transgene.
