IL-1alpha promoter constructs drive transcription of the chloramphenicol acetyltransferase (CAT) reporter gene in HTLV-I -positive MT-2 cells , which constitutively produce IL-1alpha .
 ( DNA: chloramphenicol acetyltransferase (CAT) reporter gene, None) , ( DNA: IL-1alpha promoter constructs, None) , ( protein: IL-1alpha, None) , ( protein: chloramphenicol acetyltransferase, None) , ( cell line: HTLV-I -positive MT-2 cells, None)
