Antibodies acquired naturally through repeated exposure to Plasmodium falciparum
are essential in the control of blood-stage malaria. Antibody-dependent functions
may include neutralization of parasite-host interactions, complement activation,
and activation of Fc receptor functions. A role of antibody-dependent cellular
cytotoxicity (ADCC) by natural killer (NK) cells in protection from malaria has
not been established. Here we show that IgG isolated from adults living in a
malaria-endemic region activated ADCC by primary human NK cells, which lysed
infected red blood cells (RBCs) and inhibited parasite growth in an in vitro
assay for ADCC-dependent growth inhibition. RBC lysis by NK cells was highly
selective for infected RBCs in a mixed culture with uninfected RBCs. Human
antibodies to P. falciparum antigens PfEMP1 and RIFIN were sufficient to promote
NK-dependent growth inhibition. As these results implicate acquired immunity
through NK-mediated ADCC, antibody-based vaccines that target bloodstream
parasites should consider this new mechanism of action.
