Identification of broadly inhibitory anti-PfEMP1 antibodies by mass spectrometry sequencing of plasma IgG from a malaria-exposed child


ABSTRACT: Plasmodium falciparum pathology is driven by the accumulation of parasite-infected erythrocytes in blood capillaries. We demonstrate a novel approach to identify pathogen-specific human monoclonal antibodies directly from plasma, combining mass-spectrometry analysis of antigen-purified polyclonal plasma IgG with Ig transcript sequencing.

<i>Plasmodium falciparum</i> pathology is driven by the accumulation of parasite-infected erythrocytes in blood capillaries. This sequestration process is mediated by the parasite's <i>P. falciparum</i> erythrocyte membrane protein 1 (PfEMP1) adhesins, which bind select endothelial cell receptors. A subset of PfEMP1 binding human endothelial protein C receptor (EPCR) through their cysteine-rich interdomain region alpha 1 (CIDRα1) domains drives the pathogenesis to severe malaria. Despite high se  ...[more]
