Mice suppress the parasitemia of acute blood-stagePlasmodium chabaudimalaria by an antibody- or T-cell-dependent cell-mediated mechanism of immunity (AMI and CMI, respectively) or by both mechanisms. To determine whether CD28 costimulation is required for expression of these polar immune responses, we first compared the time courses ofP. chabaudimalaria in CD28-deficient (CD28−/−) and CD28-intact (CD28+/+) mice. Acute infections in both knockout (KO) and control mice followed similar time courses, with the period of descending parasitemia being prolonged ∼2 weeks in KO mice followed by intermittent low-grade chronic parasitemia. Infected CD28−/−mice produced primarily the immunoglobulin M antibody, which upon passive transfer provided partial protection againstP. chabaudichallenge, suggesting that the elimination of blood-stage parasites by CD28−/−mice was achieved by AMI. To determine whether CD28−/−costimulation is required for the expression of CMI against the parasite, we compared the time courses of parasitemia in B-cell-deficient double-KO (JH−/−× CD28−/−) mice and control (JH−/−× CD28+/+) mice. Whereas control mice suppressed parasitemia to subpatent levels within ∼2 weeks postinoculation, double-KO mice developed high levels of parasitemia of long-lasting duration. Although not required for the suppression of acuteP. chabaudiparasitemia by AMI, CD28 costimulation is essential for the elimination of blood-stage parasites by CMI.
