how does malaria enter red blood cells

CSP is the most abundant surface protein on sporozoites and has multiple roles in sporozoite development, gliding motility, and active invasion. Broadly neutralizing epitopes in the Plasmodium vivax vaccine candidate Duffy Binding Protein. After the parasite invades, the red cells undergo profound structural and morphological changes, dramatically altering their physical properties and impairing circulation. Ankyrin peptide blocks falcipainmediated malaria parasite release from red blood cells. How do patterns of the disease vary by setting? Heinrich V. Based on these hints, Cowman compiled a list of candidate P. In contrast to normal red blood cells, parasitized cells are rigid and adhere to the lining of the blood vessels and other cell types.

Malaria kills about a million people each year; most are children and most live in Africa. But while Africa is afflicted with the deadly Plasmodium falciparum, the rest of the world is plagued by the less-lethal but still debilitating Plasmodium vivax. Now an Australian-led international team has identified the key portal used by P. Because all the clinical symptoms of malaria occur doing the blood-borne stage, the findings, published in the journal Science, deliver a new target against which to design antibodies that might not only prevent illness, but could also help finally eradicate the parasite. Papua New Guinea boasts the highest rates of infection, with the microbe exacting a high toll in debilitating illness, especially amongst children and pregnant mothers. Often this occurs when the parasite comes out of hibernation in the liver — where it causes no symptoms — and starts infecting newly minted and rare red blood cells known as reticulocytes. So a key goal has been to find a way to stop the parasite from entering them. To land a passing reticulocyte, P. One such receptor is well known — the so called Duffy antigen.

Malaria is one of the most serious and widespread parasitic disease of humans. Antigenic variation in Plasmodium falciparum. The potential mechanisms responsible for the protective effect of various red cell disorders against severe forms of malaria will be discussed.
