Recombinant human tumor necrosis factor ( TNF ) binding protein-1 ( r-h TBP-1 ) and recombinant human soluble dimeric TNF receptor ( rhu TNFR:Fc ) were used to determine the relative contributions of TNF to phorbol myristate acetate ( PMA ) and cytokine-induced human immunodeficiency virus type 1 ( HIV-1 ) replication in chronically infected cell lines.
