Note, what is the CONNECTION between the two, not what ARE the two. I need to know the CONNECTION.
Both are more prevalent in black people. Both affect the red blood cells ability to transport hemoglobin?
sickle cell can cause the person to be protected from malaria due to the way it effects the bodies immune response.the immunity increases as the person gets older.
hence why both are seen in black/asian people, as malaria is more of a risk in those countries. its the bodies attempt at protection, though sickle cell isnt very nice in itsself.
Sickle cell anemia imparts some resistance to malaria. The weakened sickle blood cell is a poor host for the malaria parasite as the cell leaks needed nutrients and is selectively eliminated by the liver.
A.Sickle cell anaemia (Heterozygous for sickle cell anemia gives resistance to malaria. That is why sickle cell anemia is more common in Africa, where malaria is also more common. ...sickle cell disease) is a disorder of the blood caused by an inherited
B. The Malarial Connection. In 1946 E.A. Beet, an MD in Northern Rhodesia noted .... How was the relationship between the higher frequency of sickle-cell trait in ... (a) Africans who had contracted malaria all had sickle-cell trait .
Hope that helps you.
Malaria is a parasite that invades the red blood cells. It requires cells that are stable for such infection. People with sickle cell anemia do not have stable red cells. They collapse and become sickled when the parasite tries to infect them. It's like a house falling apart and so people can't live there.
The second aspect to that is those who are immune to malaria then are able to live longer in malaria regions. People in that region have a higher incidence of that gene that protects them. Granted Sickle cell disease is bad and it comes about with two genes for that defect. One gene for that defect (sickle cell trait) allows the best of both worlds allowing for a long life in malarial regions and escaping most of the bad effects of sickle cell disease.
