An autologous falciparum vaccine using the erythrocyte's band 3 molecule

Medical Hypotheses

Abstract

Protection against the serious complications of falciparum malaria is provided to people with the minor forms of hematological conditions such as sickle cell disease and thalassemia and as a result natural selection has increased their incidence in malaria endemic areas. The explanation for this has thus far not been determined but experimental evidence that is now available suggest an explanation that also has therapeutic implications. The hypothesis presented suggests that the erythrocytes of these blood disorders experience premature senescence and are then eliminated by the same process that normally disposes of senescent erythrocytes. Erythrocytes express approximately one million widely dispersed band 3 molecules on their surface but when these erythrocytes age they form band 3 clusters that are recognized by the immune system which results in their elimination. In addition to senescent erythrocytes, both sickle and falciparum infected erythrocytes also display these clusters suggesting that band 3 antibodies contribute to their erythrocytes removal. Supporting band 3's involvement in falciparum erythrocyte elimination are the facts that band 3 specific antibodies are elevated in falciparum endemic areas and the documenta...Continue Reading

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
