Bidirectional concentration-dependent effects of tumor necrosis factor alpha in Shigella dysenteriae-related seizures.

چکیده
We have previously demonstrated that pretreatment of mice with Shigella dysenteriae sonicate enhanced their susceptibility to pentylenetetrazole-induced seizures and that tumor necrosis factor alpha (TNF-alpha) was proconvulsive in this respect. The present study shows that TNF-alpha, at high concentrations, may also exert a suppressive effect on Shigella-mediated seizures. This implies that high levels of TNF-alpha may play a protective role in neurologic complications of S. dysenteriae infection.

Shiga toxin type 1 activates tumor necrosis factor-alpha gene transcription and nuclear translocation of the transcriptional activators nuclear factor-kappaB and activator protein-1.
Shiga toxins (Stxs) produced by Shigella dysenteriae 1 and Escherichia coli have been implicated in the pathogenesis of bloody diarrhea, acute renal failure, and neurologic abnormalities. The pathologic hallmark of Stx-mediated tissue damage is the development of vascular lesions in which endothelial cells are swollen and detached from underlying basement membranes. However, in vitro studies us...
متن کاملConcentrations of interleukin 6 and tumour necrosis factor in serum and stools of children with Shigella dysenteriae 1 infection.
Serum interleukin 6 (IL-6) and tumour necrosis factor (TNF) were measured in children with dysentery during an epidemic caused by Shigella dysenteriae 1. IL-6 and TNF were also measured in fresh stool filtrates from children with acute gastroenteritis. The median serum IL-6 concentration was raised significantly in the children with complications (haemolytic uraemic syndrome, leukemoid reaction...

Infection of humans with Shiga toxin-producing Escherichia coli O157:H7 and Shigella dysenteriae 1 is strongly associated with vascular endothelial cell damage and the development of hemolytic-uremic syndrome. The cytotoxic effect of Shiga toxins on vascular endothelial cells in vitro is enhanced by prior exposure to bacterial lipopolysaccharide (LPS) or either of the host cytokines tumor necro...
متن کاملRole of nitric oxide in the enhancement of pentylenetetrazole-induced seizures caused by Shigella dysenteriae.
Convulsions and encephalopathy are frequent complications of childhood shigellosis. We studied the role of nitric oxide (NO) in Shigella-related seizures in an animal model. Pretreatment of mice with Shigella dysenteriae 60R sonicate elevated serum NO levels and enhanced the convulsive response to pentylenetetrazole (PTZ), as indicated by a higher mean convulsion score and a higher number of mi...
متن کاملTumor necrosis factor (TNF)-alpha directly inhibits human erythropoiesis in vitro: role of p55 and p75 TNF receptors.
Two tumor necrosis factor receptors (TNFRs) with molecular weights of 55 kD (TNFR-p55) and 75 kD (TNFR-p75) have recently been identified and cloned. In previous studies, TNFR-p55 has been shown to exclusively mediate bidirectional effects of TNF-alpha on committed bone marrow granulocyte-macrophage progenitor cells, whereas both TNFR-p55 and TNFR-p75 can mediate inhibition of primitive progeni...
