Abstract

Human monocytes, co-incubated for 7 days in culture with GM-CSF or IL-3 but not with IFN-gamma, exerted a variable schistosotnulicidal effect on Schistosoma mansoni parasites when grown in 96-well round-bottomed plates but not in flat-bottomed plates. Addition of LPS or IFN-gamma or both, for the last 48 h did not enhance the cidal effect. Addition of LPS but not IFN-gamma to the pre-incubated cells with GM-CSF or IL-3 markedly stimulated TNF-alpha production by the cells but not their cidal activity. The variable cidal effects obtained with the monocytes/macrophages from different donors suggest that these effects may be genetically predetermined and are possibly linked to blood group markers or to MHC class I or II antigens.
