For example, in experiments involving proviral clones with LTRs containing one or two NF-kappa B elements (and no Sp1 binding sites ), a hierarchy of cellular permissivity to virus replication ( peripheral blood lymphocytes = MT4 greater than H9 greater than CEM greater than Jurkat ) was observed.
 cell line: H9; DNA: Sp1 binding sites; DNA: LTRs; cell type: peripheral blood lymphocytes; cell line: MT4; DNA: NF-kappa B elements; cell type: lymphocytes; cell line: Jurkat; protein: NF-kappa B; cell line: CEM
