Some Suicide Attempts May Be Blamed On Parasite
2012-08-17 15:24:09

Lee Rannals for redOrbit.com — Your Universe Online A parasite may be to blame for some suicide attempts, according to research appearing in the Journal of Clinical Psychiatry. Toxoplasma gondii, or T. gondii, lies in the bodies of 10 to 20 percent of Americans, but in most it was thought to lie dormant. However, it appears as though the parasite can cause inflammation over time, which produces harmful metabolites that can damage brain cells. “Previous research has found...

Interactions Between Malaria Parasite and HIV Demonstrated With Novel Technique
2012-08-16 08:19:05

The World Health Organization estimates that in 2011 there were 216 million cases of malaria and 34.2 million people living with HIV. These diseases particularly afflict sub-Saharan Africa, where large incidence of co-infection result in high mortality rates. Yet, in spite of this global pandemic, interactions between the parasite that causes malaria, Plasmodium falciparum, and HIV-1 are poorly understood. However, a new video article in JoVE, the Journal of Visualized Experiments, that...

Researchers at Duke University Medical Center may finally have discovered why people with sickle cell disease get milder cases of malaria than individuals who have normal red blood cells. In a finding that has eluded scientists for years, Duke researchers discovered that genetic material in red blood cells may help alter parasite activity via a novel mechanism that alters parasite gene regulation. "One of the most interesting findings in our study is that the human microRNA (very small...

A targeted approach to treating toxoplasmosis, a parasitic disease, shows early promise in test-tube and animal studies, where it prevented the parasites from making selected proteins. When tested in newly infected mice, it reduced the number of viable parasites by more than 90 percent, researchers from the University of Chicago Medicine report in the Proceedings of the National Academy of Sciences. This precisely focused therapy combines short strands of "antisense" nucleic acid-like...

Sequenced Malaria Genome Provides Benefits, Difficulties In Finding A Cure
2012-08-06 11:45:07

Brett Smith for redOrbit.com - Your Universe Online After sequencing the genome of several malaria-related parasites, scientists found that the protozoans responsible for the deadly disease are very genetically diverse and therefore difficult to eradicate, according to their report published this week in the journal Nature Genetics. While the genomes of the four sequenced strains of Plasmodium vivax, a parasite that infects about 100 million people each year, indicated that...

The deadliest form of malaria is caused the protozoan Plasmodium falciparum. During its life-cycle in human blood, the parasite P. falciparum expresses unique proteins on the surface on infected blood cells. Antibodies to these proteins are associated with protection from malaria, however, the identity of surface protein(s) that elicit the strongest immune response is unknown. Dr. James Beeson and colleagues at the Walter and Eliza Hall Institute of Medical Research in Victoria, Australia...

Vigilance Needed Against Evolution Of More-Virulent  Malaria Shown By Vaccine Research
2012-08-01 07:57:06

Malaria parasites evolving in vaccinated laboratory mice become more virulent, according to research at Penn State University. The mice were injected with a critical component of several candidate human malaria vaccines that now are being evaluated in clinical trials. "Our research shows immunization with this particular type of malaria vaccine can create ecological conditions that favor the evolution of parasites that cause more severe disease in unvaccinated mice," said Andrew Read, Alumni...

(Ivanhoe Newswire) — According to research from Penn State University, malaria parasites evolving in vaccinated laboratory mice become more lethal. The mice were injected with a critical component of several candidate human malaria vaccines that are currently being evaluated in clinical trials. "Our research shows immunization with this particular type of malaria vaccine can create ecological conditions that favor the evolution of parasites that cause more severe disease in...
