Release date- 29082019 - Researchers at the University of Bristol and Imperial College London have established a new model system that uses red
blood cells grown in the laboratory to study how malaria parasites invade red
blood cells.
"These individuals are monitored and, if necessary, given blood and/or platelet transfusions and injected growth factors, which stimulate the development of
blood cells and decrease the need for transfusions," Dr.
Patients with the sickle cell disease have a single mutation in the gene that encodes hemoglobin, the protein that allows red
blood cells to carry oxygen.
One effect of their elevated level is permanently changing the function of proteins, including the one that helps red
blood cells maintain their normal negative charge.
In Diamond-Blackfan, other mature
blood cells such as platelets, T cells and B cells still fare well despite mutations of ribosomal protein or GATA1 genes.
* MCV: Mean Corpuscular Volume, also Mean Cell Volume, a measurement of the average volume of red
blood cells. The MCV may be elevated in liver disease or vitamin B12 deficiency.
As a result, these red
blood cells become sickle-shaped and have difficulty passing through small blood vessels preventing blood to reach all parts of the body which in turn damages tissue that does not receive a normal blood flow.
Ordinarily, malaria-causing parasites seal themselves behind two membranes inside red
blood cells of infected people.
"One of the major directions we can now go is to revisit the entire
blood cell hierarchy and sec how the current knowledge holds true when we use this internal labeling system."
