1 The downmodulation of CXCR1 and CXCR2 by LPS and TNF-alpha was most dramatically inhibited by metalloproteinase inhibitors; 1, 10-phenanthroline and EDTA significantly attenuated LPS- and TNF-alpha-induced loss of CXCR1 and CXCR2 cell surface expression. 1,10-phenanthroline tumor necrosis factor Homo sapiens
2 In addition, while treatment of neutrophils with LPS and TNF-alpha inhibited IL-8 receptor-mediated calcium mobilization and IL-8-directed neutrophil chemotaxis, both 1, 10-phenanthroline and EDTA blocked these inhibitory processes. 1,10-phenanthroline tumor necrosis factor Homo sapiens
