3 ), or to desferrioxamine (DFX), an iron chelator preventing the synthesis of OH., enhanced the specific binding of 125I-TNF-alpha to its receptors. Deferoxamine tumor necrosis factor Homo sapiens
4 ), or to desferrioxamine (DFX), an iron chelator preventing the synthesis of OH., enhanced the specific binding of 125I-TNF-alpha to its receptors. Iron tumor necrosis factor Homo sapiens
5 DFX-induced up-regulation of 125I-TNF-alpha binding depended on the concentration of the drug (1-5 mM) and on the duration of the treatment (1-18 h). Deferoxamine tumor necrosis factor Homo sapiens
6 Scatchard analysis of binding data revealed that DFX caused an approximately two-fold increase in the number of type II TNF-alpha receptors, with no change in their affinity. Deferoxamine tumor necrosis factor Homo sapiens
