Finding has implications for effectiveness of potential vaccines A mutation on the surface of human red blood cells provides protection against malaria caused by the parasite Plasmodium vivax, research led by Case Western Reserve University School of Medicine shows. The minute change, at a single position of red blood cell surface protein called the Duffy blood-group antigen, has been known for years. But the researchers found this difference makes it harder for the parasite to lock...

Study proves blood-stage infection due to population mixing and disease evolution In a paradigm changing discovery, Plasmodium vivax (P. vivax) malaria has been identified in a population historically thought to be resistant to the disease, those who do not express the Duffy blood group protein on their red blood cells, according to researchers from Case Western Reserve University School of Medicine, Pasteur Institute, and the Madagascar Ministry of Health. In a study of more than 600...

WASHINGTON, July 20 /PRNewswire-USNewswire/ -- From the start of the HIV epidemic, it appeared that some of the people who were infected with the virus were able to ward off the fatal effects of the disease longer than others. Recent studies have begun to unravel the cause of this phenomenon, and new research suggests that African Americans with the disease have a unique survival advantage if they have both a low white blood cell count (known as leukopenia) and a genetic variation that is...

New research has found that a gene variant may make Africans more vulnerable to HIV infection, while also helping them live longer once infected. The genetic variation originated thousands of years ago to protect Africans from malaria, the researchers said Wednesday. The gene involved in the study controls a surface protein on red blood cells. Those with the genetic variation were found to have a 40 percent higher risk of becoming infected with HIV, researchers in the United States and...
