Pertussis toxin isolated from Bordetella pertussis phase I strain Tohama enhanced the migration of human blood monocytes in an assay with a multiwell chemotaxis assembly. The monocyte migration enhancement by pertussis toxin was abolished by heating at 100°C for 30 min, which caused a complete loss of the other biological activities of pertussis toxin. Checkerboard analysis demonstrated that the increased monocyte migration caused by pertussis toxin was directed toward a positive stimulus: chemotaxis.
