Human antibodies to the polymorphic block 2 domain of the Plasmodium falciparum merozoite surface protein 1 (MSP-1) exhibit a highly skewed, peptide-specific light chain distribution.

Abstract

Antibodies to polymorphic block 2 of the Plasmodium falciparum merozoite surface protein 1 (MSP-1) present a paradoxical association with acquired protection against clinical malaria, while showing restricted and fixed specificity, reminiscent of antigenic sin. We report here that these antibodies present a highly imbalanced, peptide-specific light chain distribution. This was not observed with several other parasite-derived peptides or antigens. These data point to a skewed immune response to MSP-1 block 2 that is constrained both in specificity and chain usage. This is the first report of a biased response to polymorphic epitopes of a surface antigen in malaria parasites.
