• W92462908 abstract "Astrocytes have been recognized as important elements in controlling inflammatory as well as immune processes in the central nervous system (CNS). Recently, glial cells have been shown to produce cysteinyl leukotrienes (CysLTs) which are known lipid mediators of inflammation and whose extracellular concentrations rise under different pathological conditions in the brain. In the same conditions also extracellular concentrations of ATP dramatically increase reaching levels able to activate P2X 7 ionotropic receptors for which an emerging role in neuroinflammation and neurodegeneration has been claimed. RT-PCR analysis showed that primary cultures of rat brain astrocytes express P2X 7 receptors. Application of the selective P2X 7 agonist benzoyl-benzolyATP (BzATP) markedly increased [Ca 2+ ] i which was mediated by a calcium influx from the extracellular milieu. The P2X 7 antagonist, oATP, suppressed the BzATP-induced calcium increase. Consistent with the evidence that increased calcium levels activate the leukotriene biosynthetic pathway, challenge of astrocytes with either the calcium ionophore A23187 or BzATP significantly increased CysLT production and the cell pre-treatment with EGTA abolished these effects. Again the P2X 7 antagonist prevented the BzATP-mediated CysLT efflux, whereas the astrocyte pre-treatment with MK-571, a CysLT, receptor antagonist, was ineffective. The astrocyte pre-treatment with a cocktail of inhibitors of ATP binding cassette (ABC) proteins reduced the BzATP-mediated CysLT production confirming that ABC transporters are involved in the release of CysLTs. The astrocyte P2X 7 -evoked rise of CysLT efflux was abolished in the presence of MK-886, an inhibitor of 5-lipoxygenase activating protein (FLAP) whose expression, along with that of 5′-lipoxygenase (5-LO) was reported by Northern Blot analysis. The stimulation of P2X 7 induced an up-regulation of FLAP mRNA that was reduced by the antagonist oATP. These data suggest that in rat brain cultured astrocytes P2X 7 ATP receptors may participate in the control of CysLT release thus further supporting a role for extracellular ATP as an integral component of the inflammatory brain response." @default.
