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. Cytogenetic analysis of the three cell lines showed a female rat karyotype with 42 chromosomes. The surface phenotypes of TARS-1 and TART-1 were those of rat T cells. TARL-2 was only positive for rat Ia and leukocyte common antigens. The cell lines continuously produced a type C retrovirus, human T cell leukemia virus (HTLV) and expressed ATL-associated antigens. TARS-1 and TART-1, but not TARL-2 were transplantable into newborn syngeneic rats and nude mice. These results strongly indicate that HTLV not only immortalizes, but also transforms rat T cells in vitro. Adult rats immunized with either TARS-1 or TARL-2 produced antibodies specific for HTLV. The biochemical analysis of the antigens that reacted with rat sera revealed that they are the two HTLV-specific polypeptides, p24 and p28.
在5-溴-2'-脱氧尿苷(BrdUrd)存在的情况下,将雌性Wistar-King-Aptekman大鼠的脾细胞、淋巴结细胞和胸腺细胞与短期培养的成年雄性T细胞白血病(ATL)细胞共培养,建立了大鼠淋巴细胞系TARS-1、TARL-2和TART-1。对这三个细胞系的细胞遗传学分析显示为具有42条染色体的雌性大鼠核型。TARS-1和TART-1的表面表型为大鼠T细胞的表型。TARL-2仅对大鼠Ia和白细胞共同抗原呈阳性。这些细胞系持续产生一种C型逆转录病毒,即人类T细胞白血病病毒(HTLV),并表达ATL相关抗原。TARS-1和TART-1可移植到新生同基因大鼠和裸鼠体内,而TARL-2则不能。这些结果有力地表明,HTLV不仅能使大鼠T细胞永生化,还能在体外使其发生转化。用TARS-1或TARL-2免疫成年大鼠可产生针对HTLV的特异性抗体。对与大鼠血清反应的抗原进行生化分析表明,它们是两种HTLV特异性多肽,即p24和p28。
