Methods: Eleven B-CLL patients were studied. Leukemic lymphocytes with (n=8) or without (n=3) P2z receptors were exposed in vitro to ATP, benzoylbenzoic-ATP, 2-methylthio-ATP(2MeSATP), adenosine-5′-［γ-thio］ triphosphate, and other nucleosides for 8h. Apoptosis was detected by electron microscopy, agarose gel electrophoresis, and quantitative TdT assay. Results:Apoptosis was detected only in leukemic lymphocytes with P2z receptors. By using the quantitative assay, ATP-inducing DNA strand breaks were found to occur specifically for BzATP, ATP and 2MeSATP, but not for ATP-γS and other nucleosides.
