To determine activation status of the IL-2R -associated ( Jak/STAT ) pathway in the HTLV-I infected cells , we examined tyrosine phosphorylation of Jak3 , STAT3 , and STAT5 in several HTLV-I(+) T-cell lines and in uncultured leukemic T cells isolated from patients with adult T-cell lymphoma/leukemia ( ATLL ).
 ( protein: Jak3, None) , ( protein: STAT5, None) , ( cell type: uncultured leukemic T cells, None) , ( protein: STAT3, None) , ( cell line: HTLV-I infected cells, None) , ( protein: IL-2R, None) , ( protein: Jak/STAT, None) , ( cell line: HTLV-I(+) T-cell lines, None)
