ADF also enhanced IL 2-R expression of a rat T cell line transformed by HTLV-1(TARS-1), as demonstrated with anti-rat IL 2 receptor monoclonal antibodies (ART-18).
Cocultivation of spleen cells, lymph node cells, and thymocytes of female Wistar-King-Aptekman rats with short-term cultured male adult T cell leukemia (ATL) cells in the presence of 5-bromo-2'-deoxyuridine (BrdUrd) resulted in the establishment of rat lymphoid cell lines, TARS-1, TARL-2, and TART-1.
