[Generation of transgenic animals, expressing alpha- and beta-chains of autoreactive TCR].

Transgenic animal studies has become a key approach for gene function analysis as well as for modeling of different human diseases, including autoimmune diseases caused by activation of T-lymphocyte clones whose TCRs possesses high affinity for syngeneic MHC molecules. In this study we cloned genes, encoding alpha- and beta- chains of autoreactive TCR of hybridoma 7, specific for syngeneic MHC class II molecules A(b). Amplified DNA fragments, containing rearranged genomic DNA of alpha- and beta-chains of hybridoma 7 were cloned into special cassette vectors, containing natural promoter and enhancer elements for direct expression of genes encoding TCR alpha- and beta-chains in T-lymphocytes of transgenic animals.
