It was investigated whether the adjuvant formulation based on the synthetic immunomodulators B30-MDP and LA-15-PH, can influence the induction of biologically active mouse anti-gp195 (the major merozoite surface protein ofP. falciparum) antibodies. Mouse sera were obtained from a previous study in which C57Bl/10 SnJ mice were immunized ip 4 times at 21-day intervals with purified gp195 in different adjuvant formulations based on B30-MDP and LA-15-PH. Alum and CFA were used as reference adjuvants. Preimmune sera were obtained prior to immunization and immune sera were collected 14 and 21 days after the quarternary immunization.In vitroassays using various concentrations of mouse sera supplemented with 15% normal human serum did not support parasite growth. Therefore total polyclonal antibodies from mouse sera were purified by ammonium sulfate precipitation and parasite growth inhibition assays were performed. Normal mouse immunoglobulin fractions supported thein vitrodevelopment ofP. falciparumparasites. Antibodies from mice immunized with gp195 in LA-15-PH inhibited >80% of the parasitesin vitrobut antibodies from other adjuvant groups produced little or no inhibition (0-25%). This finding that LA-15-PH induced inhibitory antibodies, while other adjuvants did not, contrasts with findings in previous studies with rabbits. It is believed that this result shows that the overall effect of adjuvant formulations on the quality of immune responses is species dependent. It is also concluded that these studies emphasize the significance of the role of adjuvants on the specificity of the immune response and, more importantly, on the induction of biologically relevant antibody populations which may be indicative of protective immunityin vivo.
