title: Production of cytokines during interaction of peripheral blood mononuclear cells with autologous ovarian cancer cells or benign ovarian tumour cells.
abstract: Cytokines produced by tumour and immune cells may play a significant role in a modulation of immune cells response against tumour. We investigated an ability of peripheral blood mononuclear cells (PBMC) of patients with early and advanced stages of ovarian cancer and from non-cancer patients to produce various cytokines in the presence or absence of autologous ovarian cancer (OC) cells or benign ovarian tumour (BOT) cells. Activated PBMC of patients with advanced stage of cancer produced slight amount of interferon gamma (IFN-gamma) and what's more, the production of IFN-gamma was decreased in the presence of OC cells. PBMC of patients with ovarian cancer or benign ovarian tumour generated comparable amounts of interleukin 6 and 10 (IL-6, IL-10), and transforming growth factor beta1 (TGF-beta1). PBMC of the patients with cancer produced higher amount of tumour necrosis factor alpha (TNF-alpha) than PBMC of non-cancer patients. We demonstrated here that the reciprocal contact of OC cells from advanced cancer with autologous PBMC altered the direction of produced cytokines and leads to the down-regulation of IFN-gamma and TNF-alpha as well as to up-regulation of immunosuppressive (IL-10, TGF-beta1) and pro-inflammatory (IL-6) cytokines production.
