title: Interleukin 1 secretion by human monocytes stimulated by the isolated polysaccharide region of the Bordetella pertussis endotoxin.
abstract: The isolated polysaccharide chain, PS-1, of the Bordetella pertussis endotoxin was examined by isoelectric focusing, SDS-polyacrylamide gel electrophoresis and gel filtration for heterogeneity and for possible contamination by the parent endotoxin. This polysaccharide, previously found to be a very potent, macrophage-dependent, polyclonal B-cell activator and to mediate the specific binding of the endotoxin to macrophages, stimulated the interleukin 1 (IL 1) secretion by human monocytes; its potency was similar to that measured for the endotoxin. It was concluded that endotoxin-induced IL 1 production may be initiated by the interaction of the polysaccharide chain of the B. pertussis endotoxin and a specific structure present on macrophages.
