Interaction between cytochalasin B-treated malarial parasites and erythrocytes. Attachment and junction formation

We have previously demonstrated that invasion of erythrocytes (RBCs) by malaria merozoites follows a sequence: recognition and attachment in an apical orientation associated with widespread deformation of the RBC, junction formation, movement of the junction around the merozoite that brings the merozoite into the invaginated RBC membrane, and sealing of the membrane. In the present paper, we de...

Recognition and invasion of human erythrocytes by malarial parasites: contribution of sialoglycoproteins to attachment and host specificity

The receptivity of human erythrocytes to invasion by Plasmodium falciparum merozoites can be decreased by neuraminidase or trypsin treatment, an observation that supports a role for the erythrocyte sialoglycoproteins (glycophorins) in invasion. We have found that alpha 1-acid glycoprotein (AGP), added to in vitro cultures, can restore invasion of enzyme-treated human erythrocytes. AGP is struct...

Erythrocyte entry by malarial parasites. A moving junction between erythrocyte and parasite

Invasion of erythrocytes by merozoites of the monkey malaria, Plasmodium knowlesi, was investigated by electron microscopy. The apical end of the merozoite makes initial contact with the erythrocyte, creating a small depression in the erythrocyte membrane. The area of the erythrocyte membrane to which the merozoite is attached becomes thickened and forms a junction with the plasma membrane of t...
