The effects of ethanol and acetaldehyde on the metabolism of prostaglandin E2 and leukotriene B4 in isolated rat hepatocytes.
The effects of ethanol and acetaldehyde on the metabolism of leukotriene B4 (LTB4) and PGE2 were investigated in isolated cultures of rat hepatocytes. LTB4 undergoes initial cytochrome P450-dependent omega-oxidation leading to the principal metabolites 20-hydroxy-LTB4, 20-carboxy-LTB4 and the omega/beta-oxidation product 18-carboxy-LTB4. The addition of low concentrations of ethanol (25 mM) dra...
متن کاملThe role of interleukin-6 in lipopolysaccharide-induced fever by mechanisms independent of prostaglandin E2.
Fever has been shown to be elicited by prostaglandin E(2) (PGE(2)) binding to its receptors on thermoregulatory neurons in the anterior hypothalamus. The signals that trigger PGE(2) production are thought to include proinflammatory cytokines, such as IL-6. However, although the presence of IL-6 is critical for fever, IL-6 by itself is not or only weakly pyrogenic. Here we examined the relations...
متن کاملInduction of Apoptosis in Thymocytes by Prostaglandin E2 In Vivo
In vivo administration in mice of a synthetic analog of prostaglandin E2 (PGE2) caused a selective and dramatic decrease of CD4+CD8+ double-positive, CD3/T-cell-receptor-alpha beta(lo) cells in the thymus. This loss was corticosteroid-independent and not affected by Cyclosporin A. The disappearance of CD4+CD8+ thymocytes was strictly correlated with the induction of apoptosis inside the thymus ...
متن کاملInduction of labour using prostaglandin E2 pessaries.
The blanket use of prostaglandin E2 pessaries, as reported by Mr J H Shepherd and his colleagues (14 July, p 108), does concern me. While they did draw attention to the need for fetal monitoring in such patients, I wonder how satisfactorily this can be achieved, especially in relatively high-risk cases, under such circumstances and whether such monitoring could not be better achieved by direct...
متن کاملDynamics of interleukin-6 internalization and degradation in rat hepatocytes.
We have investigated the dissociation, internalization, and degradation of 125I-interleukin-6 (125I-IL-6) by primary rat hepatocytes. Temperature shift experiments following saturation binding of 125I-IL-6 to cell surface receptors in hepatocytes showed a rapid loss of surface-bound 125I-IL-6 (t1/2 = 15 min), concomitant with a rapid rise in internalized radiolabeled ligand. After reaching a ma...
