title: Plasmodium falciparum: production of human antibodies specific for the MSP-3 protein in the Hu-SPL-SCID mouse.
abstract: Human immunity against Plasmodium falciparum malaria is mediated by IgG antibodies. One of the major targets of protective antibodies is the MSP-3 protein. Anti-MSP-3 human monoclonal antibodies could therefore be valuable for passive immunotherapy, particularly of drug resistant malaria. Human monoclonal antibodies were previously produced in the Hu-SPL-SCID model reconstituted with human splenocytes, immunized by highly immunogenic neo-antigen or a recall antigen. We report here that this model can also be successfully employed to induce human antibody-secreting cells specific of low immunogenicity neo-antigens, such as MSP-3. These cells represent a new and valuable source of human monoclonal anti-malaria antibodies.
