To evaluate the role of erythrocyte (RBC) membrane proteins in the invasion and maturation of Plasmodium falciparum, the authors have studied, in culture, abnormal RBCs containing quantitative or qualitative membrane protein defects. These defects included hereditary spherocytosis (HS) due to decreases in the content of spectrin (HS(Sp{sup +})), hereditary elliptocytosis (HE) due to protein 4.1 deficiency (HE(4.1{sup 0})), HE due to a spectrin {alpha}I domain structural variant that results in increased content of spectrin dimers (HE(Sp{alpha}{sup I/65})), and band 3 structural variants. Parasite invasion, measured by the initial uptake of ({sup 3}H)hypoxanthine 18 hr after inoculation with merozoites, was normal in all of the pathologic RBCs. In contrast, RBCs from six HS(Sp{sup +}) subjects showed marked growth inhibition that became apparent after the first or second growth cycle. The extent of decreased parasite growth in HS(Sp{sup +}) RBCs closely correlated with the extent of RBC spectrin deficiency. Homogeneous subpopulations of dense HS RBCs exhibited decreased parasite growth to the same extent as did HS whole blood. RBCs from four HE subjects showed marked parasite growth and development.
