Malaria invasion of human erythrocytes
Parasitology Today, 1987The invasion of human red blood cells (RBC) by plosmodiol merozoites is a key event during malaria infection, and the inhibition o f invasion is regarded as a crucial goal of malaria vaccine development. For Plasmodium falciparum it has been suggested that the red cell sialoglycoproteins, glycophorins A, B and C, are receptors for invasion and that O ...

The American Journal of Tropical Medicine and Hygiene, 1983
Three red blood cell membrane fractions (Band 3, macromolecules exhibiting I antigenic determinants, and a delipidated glycoprotein fraction) were separated from red blood cell membranes and tested for their ability to inhibit penetration of red blood cells by Plasmodium falciparum merozoites in an in vitro inhibition assay.

Erythrocyte sialoglycoproteins and Plasmodium falciparum invasion
Transactions of the Royal Society of Tropical Medicine and Hygiene, 1983Human erythrocytes with a deficiency in glycophorin A (En(a-) cells) and glycophorin B (S-s-U- and S-s-U+ cells) show significant resistance in vitro to invasion by Plasmodium falciparum merozoites. Treatment of normal erythrocytes with trypsin and chymotrypsin also reduced invasion.

Erythrocytic schizogony and invasion of Plasmodium vivax in vitro
International Journal for Parasitology, 1988Abstract Several isolates of Plasmodium vivax were cultured in vitro using a culture procedure specially modified to enhance the reinvasion rate of parasites. Between 30 and 40 h after start of the culture with blood containing mainly ringforms and young trophozoites, parasites were concentrated on Nycodenz gradients.

The Role of Calcium in the Invasion of Human Erythrocytes by Plasmodium falciparum
Molecular and Biochemical Parasitology, 1992The role of calcium in the invasion of human erythrocytes by Plasmodium falciparum merozoites has been investigated using a variety of techniques. It has been demonstrated using calcium-depleted medium that invasion is dependent upon the presence of calcium and that neither magnesium, manganese or zinc may substitute for it, suggesting that the effect ...

Multiple invasion of erythrocyte by malaria parasites
Transactions of the Royal Society of Tropical Medicine and Hygiene, 1970Abstract 13 cases of light and heavy infections with P. vivax, P. falciparum, P. ovale and P. malariae were studied. The results suggest a positive correlation between multiple invasion of erythrocytes and the intensity of parasitaemia.

Staurosporine Inhibits Invasion of Erythrocytes by Malarial Merozoites
Experimental Parasitology, 1994Staurosporine, a protein kinase inhibitor, inhibits the invasion of rhesus by Plasmodium knowlesi merozoites with an IC50 of 250 nM. The drug exerts its effects primarily on the merozoite, with little or no effect on the erythrocyte. Okadaic acid, an inhibitor of protein phosphatases, can partially abrogate the inhibitory effects of staurosporine ...

Invasion of canine erythrocytes by Bartonella vinsonii subsp. berkhoffii
Veterinary Microbiology, 2012Bartonella vinsonii subsp. berkhoffii is a recognized cause of endocarditis in dogs and human patients and has been associated with cardiac arrhythmias, myocarditis, granulomatous lymphadenitis, polyarthritis, and granulomatous rhinitis in dogs. Little is known regarding the mode of transmission or cellular localization of this bacteria following ...

Hydrophobic interactions in Plasmodium falciparum invasion into human erythrocytes
Molecular and Biochemical Parasitology, 1984Human glycophorins block in vitro invasion of Plasmodium falciparum merozoites into human erythrocytes. A segment of glycophorin A which appears to be involved in the inhibition, is at, or adjacent to, the membrane-spanning domain of the molecule. To study the role of hydrophobic interactions in the inhibition, a series of proteins were derivatized ...

The Plasmodium falciparum Genome-- a Blueprint for Erythrocyte Invasion
Science, 2002Erythrocyte invasion by Plasmodium falciparum involves multiple ligand-receptor interactions and numerous apparent redundancies. The genome sequence of this parasite reveals new gene families encoding proteins that appear to mediate erythrocyte invasion.
