Název v původním jazyce

Dynamics of cytokine production in human peripheral blood mononuclear cells stimulated by LPS or infected by Borrelia

Popis výsledku v původním jazyce

To specify the role of individual cytokines in the immune response to pyrogens, isolated and cultivated human peripheral blood mononuclear cells (PBMC) were used for the experiments. Different pyrogens (lipopolysaccharide from Escherichia coli-LPS and live Borrelia afzelii) were applied and the time course of changes in concentrations of different cytokines in the medium was followed using the ELISA method. It was found that nonstimulated human PBMC proliferate under in vitro conditions and produce IL-6, TNF-alpha, IL-10 and finally also IL-1beta. Productions of IL-12 and INF-gamma are not changed. Proliferation of PBMC is potentiated after incubation with LPS or live Borrelia. PBMC stimulated by LPS increase the net production (stimulated minus unstimulated) of IL-1beta and TNF-alpha significantly, while production of IL-6 was smaller. A delayed increase in the production of IL-10 was also observed. Productions of IL-12 and INF-gamma were not influenced. In contrast to LPS, stimulatio
