title: The effects of human seminal plasma and PGE2 on mitogen induced proliferation and cytokine production of human splenic lymphocytes and peripheral blood mononuclear cells.
abstract: The effects of human seminal plasma (HSP) and prostaglandin E2 (PGE2) on the proliferative responses of human splenic lymphocytes and peripheral blood mononuclear cells (PBMCs) to phytohaemagglutinin (PHA), anti-CD3 and anti-CD3 plus anti-CD28 mAb have been studied. Th1 and Th2 cytokines were also measured in the supernatants of selected cultures. Both HSP and PGE2 reproducibly inhibit the proliferative response to PHA and anti-CD3 mAb in a dose dependent manner. These effects were observed with both fresh and frozen human PBMCs and splenic lymphocytes. HSP and PGE2 however were less effective in inhibiting the co-stimulatory response induced by anti-CD3 plus anti-CD28 mAb. In addition, the HSP and PGE2 treatment used inhibited the production of the Th1 cytokines IL-2 and IFNg but had a differential modulatory effect on Th2 cytokine production, namely enhancing the production of IL-6 whilst simultaneously impairing the synthesis of IL-4 and IL-10.
