Effects of molecular liposomal hybrid compositions with oxidized dextrans and isonicotinic acid hydrazide on production of granulocytic macrophage colony-stimulating factor by macrophages.
The effects of molecular liposomal hybrid compositions consisting of liposomes (200-450 nm) containing oxidized dextrans (dextranals; 35-60 kDa) conjugated with isonicotinic acid hydrazide (dextrazides), their components, and native dextrans on the production of granulocytic macrophage CSF by peritoneal macrophages were studied in vitro. Dextranals proved to be more potent inductors of granulocytic macrophage CSF than native dextrans. Conjugation of nicotinic acid hydrazide with dextranals did not modify their capacity to stimulate the production of granulocytic macrophage CSF. Liposomes in the molecular liposomal hybrid compositions did not attenuate the dextrazide capacity to stimulate the production of granulocytic macrophage CSF. Molecular liposomal compositions containing 60 kDa dextrazide exhibited the most potent stimulatory effect on macrophage production of granulocytic macrophage CSF.
