title: Glycophorin as a possible receptor for Plasmodium falciparum.
abstract: Human red cells deficient in glycophorin B are partly resistant to invasion by Plasmodium falciparum and become completely resistant when glycophorin A is removed from their surface by trypsin treatment. Similar treatment of cells which have a hybrid glycophorin molecule renders them glycophorin-deficient and resistant to invasion. Tn and Wrb -ve cells with defined alterations in glycophorin A or B are also resistant to invasion. These findings suggest that both glycophorins A and B are involved in parasite invasion, indicate which parts of these molecules may be involved in this process, and provide the basis for a tentative model of parasite/red-cell interactions.
