Adult T-cell leukemia (ATL) is a leukemia caused by a monoclonal expansion of HTLV-I-infected T-cells expressing a CD4 antigen. The clinical features of ATL include lymphadenopathy, hepatosplenomegaly, frequent skin lesions, hypercalcemia and a rapidly fatal course. The cell surface phenotype, cytogenetics and functions of leukemic cells are described in association with various clinical manifestations and HTLV-I infection. Leukemic cells constitutively express the p55 (Tac antigen) subunit of the interleukin-2 (IL-2) receptor. Its association with the function of HTLV-I gene products and its possible role in the leukemogenesis of ATL are discussed. Finally, the potential of some therapeutic agents which may selectively eliminate the Tac-expressing leukemic cells in vitro are described, and these may provide an improvement over currently ineffective combination chemotherapy.
成人T细胞白血病(ATL)是一种由感染人类T淋巴细胞病毒I型(HTLV-I)且表达CD4抗原的T细胞单克隆扩增引起的白血病。ATL的临床特征包括淋巴结病、肝脾肿大、频繁的皮肤病变、高钙血症以及快速致死的病程。白血病细胞的细胞表面表型、细胞遗传学和功能与各种临床表现及HTLV-I感染相关。白血病细胞组成性表达白细胞介素-2(IL-2)受体的p55(Tac抗原)亚基。文中讨论了其与HTLV-I基因产物功能的关联及其在ATL白血病发生中的可能作用。最后,描述了一些可能在体外选择性清除表达Tac的白血病细胞的治疗药物的潜力,这些药物可能比目前无效的联合化疗有所改进。
