Natural protection against severe Plasmodium falciparum malaria due to impaired rosette formation

Abstract excerpt

Genes for two lethal diseases, thalassemia and sickle cell anemia, are favored by evolution because, in their heterozygous form, they protect against cerebral malaria. Rosette formation, the binding of uninfected red cells (RBCs) to Plasmodium falciparum-infected RBCs (PRBCs), has previously been found to be associated with cerebral malaria, the most important severe manifestation of P falciparum malaria. We show...
