Abstract
  • In the present paper we analyzed c-fos and zif/268 expression in rat primary astroglial cell cultures after treatment with Platelet-activating Factor (PAF) and its 2-O-methyl-analogue, 1-O-octadecyl-2-O-methoxy-glycero-3-phosphocholine (ET-18-OCH3). Both compounds, at a dose (2 microM) that did not produce toxic effects on astroglial cells, induced a rapid and transient increase of c-fos and zif/268 mRNA level. Pretreatment of astroglial cells with the PAF antagonist BN50730 (5 microM) 10 min prior to the addition of alkyl-phospholipids almost completely prevented the activation of the immediate early genes. On the contrary triazolam, another PAF inhibitor, did not block PAF induced gene expression when added to the medium at 5 microM concentration. ET-18-OCH3 effect on gene expression is blocked by the same antagonist (BN50730) which is effective in inhibiting PAF effect on astrocytes, suggesting that both substances act through the same binding site. Results obtained support the view that astroglial cells are a cellular target for this lipid mediator, and, like macrophages, respond to its methoxy-analogue. (literal)
