Scientists identify gene behind malaria-resistant mosquitoes For many years, the mosquitoes that transmit malaria to humans were seen as public enemies, and campaigns to eradicate the disease focused on eliminating the mosquitoes. But, as a study published today in Science shows, the mosquitoes can also be our allies in the fight against this common foe, which kills almost one million people a year and heavily impairs the economies of affected countries. In this study, researchers at the...

Scientists in Singapore, The Netherlands and France say they developed a novel immunization method against the life-threatening malaria parasite. Principal investigator Laurent Renia of the Singapore Immunology Network says the malaria parasite, Plasmodium falciparum, infects 350 to 500 million people worldwide and kills more than 1 million people each year. It is not practical to apply the experimental method used in our study as a means of vaccination, Renia says in a statement. But, this...

In this week's New England Journal of Medicine, scientists in Singapore, The Netherlands and France report that they have developed a novel immunization method that will induce fast and effective protection in humans against the life-threatening malaria parasite, Plasmodium falciparum, which infects 350 to 500 million people world-wide and kills over one million people each year."It is not practical to apply the experimental method used in our study as a means of vaccination," said Laurent...

A new study suggests that scientists may finally be on the right track to developing an effective vaccine against malaria, one of mankind's top killers, The Associated Press reported. European researchers called it only a small proof-of-principle test that isn't practical on a large scale, but in a daring new experiment, the researchers actually used mosquitoes to deliver a "vaccine" of live malaria parasites to people through their bites. The results showed that everyone in the vaccine...

Researchers at the Johns Hopkins Malaria Research Institute have for the first time produced a malarial protein (Pfs48/45) in the proper conformation and quantity to generate a significant immune response in mice and non-human primates for use in a potential transmission-blocking vaccine. Antibodies induced by Pfs48/45 protein vaccine effectively blocked the sexual development of the malaria-causing parasite, Plasmodium, as it grows within the mosquito. Sexual development is a critical step...

Researchers have identified a group of proteins that are targeted by parasites to cause malaria. "This study reveals the identity of a novel protein trafficking apparatus ... and hence, provides an 'Achilles heel' for anti-malaria drug developers," Brendan Crabb at the Burnet Institute in Melbourne, Australia and colleagues wrote in the journal Nature. Researchers from Australia and the United States noted the discovery of an encasing vacuole that is located inside infected cells. Parasites...

As part of a worldwide push to eradicate one of the oldest and deadliest diseases still in existence, scientists at the University of Maryland are tinkering with mosquito DNA to produce insects capable of carrying a larger than normal load of the parasite responsible for malaria.Which begs the question: why would they want to produce more infectious mosquitoes? Scientists say they hope to use the genetically engineered insects to harvest more of the key ingredients needed for the world's...

Methylene blue can curb the spread of malaria parasites when administered together with new malaria medication / Heidelberg researchers publish in PLoS One New combinations of agents based on the oldest synthetic malaria drug, the methylene blue stain, can curb the spread of malaria parasites and make a significant contribution to the long-term eradication called for by the international "Roll Back Malaria Initiative." In a study on 160 children with malaria in Burkina Faso, specialists in...

Approximately 350 million to 500 million cases of malaria are diagnosed each year mostly in sub-Saharan Africa. While medications to prevent and treat malaria do exist, the demand for new treatments is on the rise, in part, because malaria parasites have developed a resistance to existing medications. Now, researchers at the Johns Hopkins University School of Medicine have discovered one way to stop malaria parasite growth, and this new finding could guide the development of new malaria...
