In malaria endemic areas, regardless of immunity acquired during lifelong exposure to malaria, pregnant women become susceptible to Plasmodium falciparum infections. Malaria during pregnancy is associated with a massive sequestration of infected erythrocytes in the placenta and the emergence of a unique parasite-derived adhesive molecule (encoded by var2CSA) that binds to chondroitin sulfate A (CSA). How P. falciparum achieves the timely expression of the CSA ligand in pregnant women remains puzzling. We investigated whether host serum-specific factors present only during pregnancy may induce var2CSA expression. Our panel of experiments did not reveal significant changes in var2CSA levels and CSA-binding capacity.
