摘要：

Human malignant T cell lines have high levels of deoxyribonucleoside phosphorylating activity and low levels of deoxyribonucleotide dephosphorylating activity. When incubated with deoxyadenosine or thymidine, the malignant T cell lines rapidly accumulate toxic concentrations of dATP and dTTP, respectively. This unusual pattern of deoxyribonucleotide metabolism renders the malignant T cells especially vulnerable to the toxic effects of deoxyribonucleosides and related analogues.
