Abstract
Summary
Eosinophils were demonstrated to be chemotactically attracted to certain mononuclear cells in an inflammatory exudate produced by a challenging injection of tetanus toxoid. The accumulation of eosinophils around specific lymphocytes, macrophages and mesothelial cells was followed by a rupture of the cell membrane and penetration of the eosinophils into the mononuclear cell. The eosinophils eventually move away from the disintegrating cells and, beginning on or about the 4th day of inflammation, are rapidly engulfed by viable macrophages.
