Macrophage migration as an index of immune status.
Peritoneal macrophages from mice and guinea pigs pretreated with Freund's complete adjuvant (FCA) or any other immunostimulant when packed in a glass capillary and placed in a migration chamber migrated to a larger area than macrophages from normal untreated animals. The extent of migration could be correlated with the dose of FCA and the period of treatment. Under optimum conditions the ratio between the areas of migration of macrophages from FCA-treated animals and of macrophages from untreated animals was above 3.0. A close correlation was observed between macrophage migration and delayed type hypersensitivity (DTH) response in animals sensitized with ovalbumin or sheep red blood cells. The macrophages of immunostimulant-treated animals had relatively higher phagocytic activity. The macrophage migration index (MMI) appears to be a close correlate of macrophage activation and possibly also of the status of cell mediated immune response.
