Although NF-kappaB/Rel factors are known to induce the expression of T-cell growth factor interleukin (IL)-2 , it is unclear how they participate in the IL-2 -independent growth of HTLV-I -transformed cells .
 ( protein: NF-kappaB/Rel factors, None) , ( cell line: HTLV-I -transformed cells, None) , ( protein: T-cell growth factor interleukin (IL)-2, None) , ( protein: IL-2, None) , ( cell type: -transformed cells, None)
