Abstract
A rabbit gamma delta killer T-cell line against Shope carcinoma cells was established from peripheral blood lymphocytes (PBL) of a human T-lymphotropic virus type I (HTLV-I)-infected rabbit bearing Shope papilloma and carcinoma. Southern hybridization analysis of this cell line with an HTLV-I probe showed that the cell line contained multiple clones of HTLV-I-transformed cells, and three sublines with different integration patterns of the HTLV-1 genome were isolated by cloning of the cell line. In all these sublines T-cell receptor (TCR)-gamma and -delta genes were rearranged and expressed. A PCR-based analysis of the expression of variable (V) genes showed that the killer cell line preferentially expressed V gamma 1.1 and V delta 1 genes, whereas V gamma 2 and V delta 1 genes were dominantly expressed in normal PBL. Analysis of the junctional sequences of TCR-gamma and -delta genes which dictate the fine specificities of epitope recognition revealed that all three sublines expressed V gamma 1.1/V delta 1 genes without the nucleotide diversity at the V-J junctions.
