    Abstract

    Wang et al. isolate a potent neutralizing human mAb, L9 that preferentially binds NVDP minor repeats of Plasmodium falciparum circumsporozoite protein (PfCSP) on sporozoites with high affinity while cross-reacting with NANP major repeats. Their findings define the subdominant PfCSP minor repeats as neutralizing epitopes and demonstrate that the liver is an important site for antibodies to prevent malaria.
