Abstract
Injection of mouse antiserum against isologous aggregated immunoglobulins (MAAS) into mice previously receiving 105 sheep red blood cells (SRBC) did not affect the intensity of the delayed-type hypersensitivity (HDT) reaction when tested at the peak of sensitization (4th day), but led to a marked increase in the intensity of the reaction in the later stages (6th day). MAAS completely abolished suppression of HDT observed after sensitization with 5·107 SRBC. Transfer experiments showed that under the influence of MAAS the number of suppressor cells of HDT in the spleen of the sensitized mice was reduced. MAAS had no effect on proliferation of antibody-forming cells or on the intensity of hemagglutinin production, but reduced by 70% the number of rosette-forming cells (RFC) detectable in the spleen at the peak of the primary immune response. The results may be evidence that RFC take part in the suppression of HDT.
