abstract = {The merozoite surface protein 1 (MSP1) is the most abundant
protein on the surface of the invasive merozoite stages of
Plasmodium falciparum and has long been considered a key
target of protective immunity. We used samples from a single
controlled human malaria challenge study to test whether the
full-length version of MSP1 (MSP1FL) induced antibodies that
mediated Fc-IgG functional activity in five independent
assays. We found that anti-MSP1FL antibodies induced
complement fixation via C1q, monocyte-mediated phagocytosis,
neutrophil respiratory burst, and natural killer cell
degranulation as well as IFNγ production. Activity in each
of these assays was strongly associated with protection. The
breadth of MSP1-specific Fc-mediated effector functions was
more strongly associated with protection than the individual
measures and closely mirrored what we have previously
reported using the same assays against merozoites. Our
findings suggest that MSP1FL is an important target of
functional antibodies that contribute to a protective immune
response against malaria.},
