摘要

Interleukin (IL)-5 has been shown to play an essential role in the pathogenesis of airway inflammation. We investigated the effect of 4-(2-chlorophenyl)-2-[2-(4-isobutylphenyl)ethyl]-6, 9-dimethyl-6 H -thieno[3,2- f ][1,2,4]triazolo[4,3- a][1,4]diazepine (Y-24180), an antagonist of platelet-activating factor (PAF), on the production of IL-5 in cultured D10.G4.1 cells, a murine Th(2)clone, and human peripheral blood mononuclear cells (PBMC). As a result, Y-24180 was found to suppress both the mRNA expression of IL-5 and the subsequent secretion of this cytokine in antigen-stimulated D10.G4.1 cells. Y-24180 also suppressed the production of IL-4, another Th(2)type cytokine, at the level of mRNA expression, however, it hardly affected the mRNA expression for IL-6 or IL-10, thus indicating it to have a selective action against IL-5 and IL-4. The suppressive effect of Y-24180 on the secretion of IL-5 by human PBMC was more potent than that of WEB2086, which is another PAF-antagonist. These results suggest that Y-24180 suppresses IL-5 production through a common pathway which also affects the production of IL-4, even though the mechanism remains to be elucidated as to whether the PAF-antagonistic actions are involved or not.
