ABSTRACT
Although prostaglandin E2 (PGE2) is a pro-inflammatory mediator, it also produces some effect which is anti-inflammatory in character. It is suggested that one of the mechanisms responsible for the latter effect is the increased synthesis of IL-10. The aim of this study has been to determine the influence of PGE2 on IL-10 production by bovine CD4+ and CD8+ T cells and NK cells. With this aim, peripheral blood mononuclear cells collected from 12-month-old heifers (n = 10) were treated without or with PGE2 (10(-6) M). Flow cytometric analysis showed that PGE2 caused a reduction in the percentage of IL-10 producing CD4+ T cells (P < 0.001), while leaving the secretion of this cytokine by CD8+ T cells and NK cells unaffected. This seems to indicate that PGE2 in cattle does not produce an anti-inflammatory effect by increasing the synthesis of IL-10; contrary to this, it may aggravate an inflammatory response by inhibiting the secretion of this cytokine by CD4+ T cells.
