Abstract
The abnormal lymphocytes in adult T cell leukemia (ATL) reveal a peculiar morphology that is characterized by indented or lobulated nuclei. While human T lymphotropic virus type I (HTLV-I) is thought to be integrated in ATL cells, the correlation between the nuclear irregularities and HTLV-I infection is obscure. We have devised a novel single cell polymerase chain reaction (PCR) technique to examine the integration of HTLV-I provirus genome in cells from two patients with ATL. To isolate single cells, peripheral blood smears were prepared on thin polyester slides and stained with May–Grünwald–Giemsa. Morphologically defined single cells were cut out after light microscopy. The HTLV-I DNA sequences were detected not only in ATL cells but also in normal-looking lymphocytes. This novel PCR method may provide a valuable tool for understanding the molecular events associated with HTLV-I infection at the single cell level.
