Researchers Identify How Mosquito Immune System Attacks Specific Infections Researchers at the Johns Hopkins Bloomberg School of Public Health have determined a new mechanism by which the mosquitoes´ immune system can respond with specificity to infections with various pathogens, including the parasite that causes malaria in humans, using one single gene. Unlike humans and other animals, insects do not make antibodies to target specific infections. According to the Johns Hopkins...

Their finding challenges the widely-accepted theory that Plasmodium falciparum, which causes the most lethal form of malaria, is the only malaria parasite capable of driving genome evolution in humans. The study was published today in the journal PLOS Medicine. Professor Ivo Mueller from the Walter and Eliza Hall Institute and Barcelona Centre for International Health Research (CRESIB) led the study, with colleagues from the Papua New Guinea Institute of Medical Research, Centre of Global...

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...

Sequenced Malaria Genome Provides Benefits, Difficulties In Finding A Cure

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...

Scientists from the Zoological Society of London (ZSL) are the first to document the characteristics of invading parasites, using malaria in New Zealand bird species. The study, published today in Ecology Letters, identifies the factors influencing the success of parasites unintentionally introduced to new environments. Avian malaria is a disease caused by species of parasites, of the genus Plasmodium, which infects birds. Just like human malaria, it is spread by mosquitoes, and the...

Can Genetics Prevent The Transmission Of Malaria?

redOrbit Staff & Wire Reports - Your Universe Online Malaria kills more than 800,000 people worldwide every year and many of those victims are children. Researchers are now reporting that they have genetically modified a bacterium commonly found in the mosquitos mid gut and found that the parasite that causes malaria in people does not survive in mosquitoes carrying the modified bacterium. The researchers, from the Johns Hopkins Malaria Research Institute, modified the bacterium...


Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
