Recombinant granulocyte/macrophage colony-stimulating factor (rGM-CSF) obtained from cloned complementary Mo cell DNA and expressed in COS-1 cells activates cultured peripheral blood monocyte-derived macrophages in vitro to become cytotoxic for intracellular L. donovani. The antileishmanial effect of rGM-CSF, which can be completely neutralized by anti-rGM-CSF antiserum, is maximal after 36 h preincubation with the cultured macrophages, compared with that of rIFN-gamma, which reaches its maximum at 72 h of preincubation. The antileishmanial effect of GM-CSF as well as IFN-gamma is independent of detectable amounts of LPS and is not augmented by the addition of 10 or 50 ng/ml of LPS. Simultaneous administration of suboptimal doses of rGM-CSF and rIFN-gamma to monocyte-derived macrophages results in greater antileishmanial activity by these cells than administration of either lymphokine alone, although no enhancement of antileishmanial activity is observed when optimal doses of these two lymphokines are applied together.

Macrophage colony-stimulating factor (M-CSF or CSF-1) and granulocyte- macrophage CSF (GM-CSF) have been shown to increase human monocyte urokinase-type plasminogen-activator (u-PA) activity with possible consequences for cell migration and tissue remodeling; because monocyte u-PA activity is likely to be controlled in part also by the PA inhibitors (PAIs) made by the cell, the effect of M-CSF and GM-CSF on human monocyte PAI-2 and PAI-1 synthesis was investigated. To this end, elutriation-purified human monocytes were treated in vitro with purified recombinant human M-CSF and GM-CSF, and PAI-2 and PAI-1 antigen and mRNA levels measured by specific enzyme-linked immunosorbent assays and Northern blot, respectively. Each CSF could enhance the protein and mRNA levels of PAI-2 and PAI-1 at similar concentrations for each product. This similar regulation of monocyte PAI expression in response to the CSFs contrasted with that found for the effects of lipopolysaccharide, transforming growth factor-beta and a glucocorticoid. Therefore, PAIs may be modulating the effects of the CSFs on monocyte u-PA activity at sites of inflammation and tissue remodeling.
