To analyze the mechanisms that lead to the expression of IL-1alpha in HTLV-I -infected cell lines , we studied regulatory regions of the human IL-1alpha promoter involved in activation of the IL-1alpha gene .
 ( DNA: IL-1alpha gene, None) , ( cell line: HTLV-I -infected cell lines, None) , ( protein: IL-1alpha, None) , ( protein: IL-1alpha, None) , ( protein: IL-1alpha, None) , ( DNA: IL-1alpha promoter, None)
