The goal of this study was to analyze antibody responses to
Plasmodium falciparum glutamate-rich protein (GLURP) using
clinical data and plasma samples obtained from villagers of Dielmo,
Senegal. This molecule was chosen because it is targeted by human
antibodies which induce parasite growth inhibition in
antibody-dependent cellular inhibition (ADCI) assays. The results
showed a strong correlation between protection against malaria attacks
and levels of immunoglobulin G2 (IgG2) and IgG3 against
GLURP94-489 (R0) and IgG3 against
GLURP705-1178 (R2) when corrected for the confounding
effect of age-related exposure to malaria. Thus, GLURP may play a role
in the induction of protective immunity against P. falciparum malaria.
