Herb Holds Promise as Treatment for Ebola Virus Disease
February 27th 2015New research that focuses on the mechanism by which Ebola virus infects a cell and the discovery of a promising drug therapy candidate published Feb. 27 in the journal Science. Dr. Robert Davey, scientist and Ewing Halsell Scholar in the Department of Immunology and Virology at Texas Biomedical Research Institute announced today that a small molecule called Tetrandrine derived from an Asian herb has shown to be a potent small molecule inhibiting infection of human white blood cells in vitro or petri dish experiments and prevented Ebola virus disease in mice.
Malaria Transmission Linked to Mosquitoes' Sexual Biology
February 27th 2015Sexual biology may be the key to uncovering why Anopheles mosquitoes are unique in their ability to transmit malaria to humans, according to researchers at Harvard T. H. Chan School of Public Health and University of Perugia, Italy. Through analysis of 16 Anopheles genomes, they found that these mosquitoes’ reproductive traits evolved along with their capacity to transmit the Plasmodium parasite that causes malaria. These findings may provide a new target for malaria control, particularly in regions hardest hit by the disease.
Malaria Plays Hide-and-Seek with Immune System by Using Long Noncoding RNA to Switch Genes
February 27th 2015Up to 1 million people -- mainly pregnant woman and young children -- are killed each year by the Plasmodium falciparum parasite, which causes the most devastating form of human malaria. Now, researchers at the Hebrew University of Jerusalem have revealed the genetic trickery this deadly parasite deploys to escape attack by the human immune system.
Warning Signals from the Volatile World of Influenza Viruses
February 27th 2015The current global influenza situation is characterized by a number of trends that must be closely monitored. These include: an increase in the variety of animal influenza viruses co-circulating and exchanging genetic material, giving rise to novel strains; continuing cases of human H7N9 infections in China; and a recent spurt of human H5N1 cases in Egypt. Changes in the H3N2 seasonal influenza viruses, which have affected the protection conferred by the current vaccine, are also of particular concern.
PLOS Currents Collection Investigates Vaccine Hesitancy and Vaccination Decision-Making
February 25th 2015Researchers explore individuals' confidence or reluctance to vaccinate their families and the associated effects on global health, in a collection published on Feb. 25 by the open-access journal, PLOS Currents: Outbreaks. The collection is accompanied by the editorial "Hesitancy, trust and individualism in vaccination decision-making" by Jonathan E. Suk et al. from the European Centre for Disease Prevention and Control (ECDC).
Polio Vaccination with Microneedle Patches Receives Funding for Patch Development, Clinical Trial
February 25th 2015The Georgia Institute of Technology and Micron Biomedical have been awarded $2.5 million in grants from the Bill & Melinda Gates Foundation to advance the development of dissolvable microneedle patches for polio immunization. The patches will be studied to evaluate their potential role as part of the worldwide efforts to eradicate polio.
