Abstract

We examined the inhibitory actions of prostaglandin E2, histamine, isoproterenol, hydrocortisone, and interferon on lymphocyte mitogenesis. There was a high degree of intercorrelation between the amount of inhibition caused by prostaglandin E2, histamine, isoproterenol, and hydrocortisone, but not interferon, in any given subject; that is if lymphocytes from a given subject were highly sensitive to inhibition by one of those agents, they were also sensitive to the other agents. The inhibitory actions of histamine, isoproterenol, or hydrocortisone could be partially blocked by adding prostaglandin synthetase inhibitors to the mitogen cultures. Preincubation of the lymphocytes for 18 hr prior to the addition of mitogens and inhibitors resulted in a loss in sensitivity to the inhibitors other than interferon. Removal of glass-adherent cells (the prostaglandin-producing cells) prior to culture lessened the inhibition caused by histamine and isoproterenol. The above data would suggest that these inhibitors may act via prostaglandin; however, all of these compounds actually decrease prostaglandin production in cultures of peripheral blood mononuclear cells. The implications of these findings are discussed.
