Abstract

Clinical immunity to malaria is associated with the acquisition of IgG specific for members of the Plasmodium falciparum erythrocyte membrane protein 1 (PfEMP1) family of clonally variant antigens on the surface of infected erythrocytes (IEs). The VAR2CSA subtype of PfEMP1 mediates IE binding in the placenta.

  • Lopez-Perez et al. (2018) found that men and children often have high levels of functional VAR2CSA-specific IgG.

    “Accordingly, Lopez-Perez et al. (2018) conducted a study in Colombia and found that men and children often have high levels of functional VAR2CSA-specific IgG.”

    From Current update on malaria in pregnancy: a systematic review (2025) · cites this paper as Lopez-Perez et al. (2018)

    The Results (page not provided) found frequent IgG reactivity in Colombian men and children to an insect-cell-produced recombinant protein, but only 7% of their samples had IgG to its native counterpart above the cutoff. The Discussion (page not provided) cautions that recombinant-protein reactivity need not reflect recognition of native VAR2CSA. The paper therefore does not find that men and children often have high levels of functional VAR2CSA-specific IgG; it argues against that interpretation. (LLM, conf=0.91)

    Checked by a reasoning model — may be wrong.

  • IgG responses to the P.falciparum antigen VAR2CSA are specific to pregnancy and are not triggered by exposure to P.vivax.

    “This study concluded that IgG responses to the P.falciparum antigen VAR2CSA are specific to pregnancy and are not triggered by exposure to P.vivax [112].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
