[Influence of polyoxidonium on IL-1 beta, TNF-alpha and IL-6 production by mononuclears and monocytes under the dexamethasone effect].

It was established that in a mononuclear fraction polyoxidonium inhibited the TNF-alpha production and stimulated the IL-1 beta and IL-6 production. In LPS-induced mononuclear cultures polyoxidonium inhibited the IL-6 production and had no statistically significant effect on the synthesis of TNF-alpha and IL-1 beta. Polyoxidonium had no effect on TNF-alpha, IL-6 and IL-1 beta production by purified monocytes. The addition of polyoxidonium with dexamethasone to the cultures only in monocyte fraction enhanced the IL-1 beta production as compared with the effect of dexamethasone alone. Data obtained allow suggesting that under certain conditions polyoxidonium could alleviate pronounced suppressive influence of glucocorticoids on a secretory activity of effectors of innate immunity.
