Polymicrobial sepsis induced by cecal ligation and puncture (CLP) reproduces many of the pathophysiologic features of septic shock. In this study, we demonstrate that mRNA for a broad range of pro- and anti-inflammatory cytokine and chemokine genes are temporally regulated after CLP in the lung and liver. We also assessed whether prophylactic administration(More)
Cellular sensing of L-amino acids is widespread and controls diverse cellular responses regulating, for example, rates of hormone secretion, amino acid uptake, protein synthesis and protein degradation (autophagy). However, the nature of the sensing mechanisms involved has been elusive. One important sensing mechanism is selective for branched chain amino(More)
Tumor necrosis factor alpha (TNF) is thought to play a major role in the pathogenesis of septic shock. Anti-TNF antibody was preadministered in low-dose endotoxin lethality models in which BALB/c mice were challenged with small amounts of lipopolysaccharide following their sensitization with either carrageenan (CAR) or D-galactosamine (D-GalN). Although the(More)
