We have investigated the effect of tumor necrosis factor on the release of interleukin-1 and PGE2 from murine resident peritoneal macrophages. Tumor necrosis factor causes an increase in the production of interleukin-1 and PGE2 with a maximum induction for both noted at 5.9 X 10(-8) M. While indomethacin decreased tumor necrosis factor induced PGE2 production, this cyclooxygenase inhibitor augm...
BACKGROUND AND PURPOSE We earlier reported that risk factors for stroke prepare brain stem tissue for a modified Shwartzman reaction, including the development of ischemia and hemorrhage and the production of tumor necrosis factor-alpha, after a provocative dose of lipopolysaccharide. In the present study, we sought to determine whether blood and central nervous system cells of rats with the st...
Bacterial endotoxin (lipopolysaccharide) depresses cardiovascular function; however, the mediators and signaling pathways that are responsible for the negative inotropic effects of lipopolysaccharide are not fully known. We used RNA interference to determine the relative role of tumor necrosis factor with respect to mediating the negative inotropic effects of lipopolysaccharide in isolated card...
a modified Shwartzman reaction, including the development of ischemia and hemorrhage and the production of tumor necrosis factor-a, after a provocative dose of lipopolysaccharide. In the present study, we sought to determine whether blood and central nervous system cells of rats with the stroke risk factor of advanced age produce more proinflammatory and prothrombotic mediators than do those of...
