Suppression of antibody producing splenic lymphocytes by plasma from rats infected with Plasmodium chabaudi malaria was confirmed. Suppressive activity was found in plasma drawn on the sixth, seventh and eighth day of infection. It was temporally associated with anemia, elevated levels of soluble immune complex, reduced titers of lytic complement and elevated titers of immunoconglutinin (IK) in the plasma. Heat inactivation of the plasma to destroy complement and removal of IK by absorption did not reduce the suppressive activity. Incubating the plasma-treated lymphocytes with normal rat complement largely, but not completely, reversed the suppressive action. Soluble immune complexes prepared from bovine serum albumin (BSA) and antiBSA (BSA-antiBSA) alexinated complex (BSA-antiBSA-C') and immunoconglutinated complex (BSA-antiBSA-C'-IK) each suppressed the capacity of splenic lymphocytes from rats immunized with sheep blood cells to produce hemolytic Jerne plaques. Incubating the complex-treated cells with fresh complement largely reversed the suppressive activity. It is suggested that the suppressed responses of lymphocytes from malarious animals to antigens or mitogens, reported by others, may have been in part induced by complexes in blood of the animals, and that antibody producing cells might also have been suppressed. Since suppressive activity was not influenced by complement inactivation, but was reversed when plasma-treated cells were incubated with fresh complement, it is suggested that the hypocomplementemic state of suppressive plasma may have contributed to immunosuppression.
