A new quantitative analysis of more than 123,000 influenza specimens from 1918-2013 shows the Replikin Counts (number of Replikins per 100 amino acids) of the genes of H1N1 and H5N1 have increased beyond the levels of the 2009 pandemic year. London, UK (PRWEB) March 05, 2014 Replikins Ltd., which in April 2008 predicted the last H1N1 influenza pandemic of 2009, announced today that from the quantitative analysis of all of the 123,112 influenza specimens of H1N1, H2N2, H3N2, and H5N1 in...

Since its first identification in Asia, highly pathogenic avian influenza—H5N1—has caused significant alarm in the scientific community.  While the virus’ primary target is birds—tens of millions have already died from it—it is capable of infecting mammals, including humans, causing serious illness and a frightening rate of mortality. In a new study, Matthew Scotch, a researcher at Arizona State University’s Biodesign Institute, tracks the spread of an H5N1 variant in...

The avian H7N9 influenza virus that emerged earlier this year in China is poorly adapted for sustained transmission between humans, suggesting that the current form of the virus is unlikely to cause a pandemic, according to a new study led by Ian A. Wilson, Ph.D., and James C. Paulson, Ph.D., of The Scripps Research Institute (TSRI). The study, published yesterday in Science, was supported by the National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of...

Emerging Bird Flu Strain Still Poorly Adapted For Infecting Humans

Scripps Research Institute Avian influenza virus H7N9, which killed several dozen people in China earlier this year, has not yet acquired the changes needed to infect humans easily, according to a new study by scientists at The Scripps Research Institute (TSRI). In contrast to some initial studies that had suggested that H7N9 poses an imminent risk of a global pandemic, the new research found, based on analyses of virus samples from the Chinese outbreak, that H7N9 is still mainly adapted...

Study may have implications for immunity against flu Scientists at Fred Hutchinson Cancer Research Center have uncovered a new mechanism by which influenza can infect cells – a finding that ultimately may have implications for immunity against the flu. Influenza viruses have two main proteins on their surface that allow them to do their dirty work: a protein called hemagglutinin allows viruses to infect cells, while a protein called neuraminidase allows viruses to escape from cells....

Virus attaches to both upper and lower respiratory tract epithelium, according to report in The American Journal of Pathology A new study has found that a novel avian-origin H7N9 influenza A virus, which has recently emerged in humans, attaches moderately or abundantly to the epithelium of both the upper and lower respiratory tracts. This pattern has not been observed before for avian influenza A viruses. The report, published in the October issue of The American Journal of Pathology,...

Bird Flu Genetic Analysis Reveals Easy Adaptation To Humans

Lawrence LeBlond for redOrbit.com - Your Universe Online The new bird flu strain that has so far killed 11 people in China has been showing signs that it is quickly adapting to mammalian (particularly human) hosts, according to a new study led by Masato Tashiro of the Influenza Virus Research Center at the National Institute of Infectious Diseases (NIID) in Japan, along with Yoshiro Kawaoka of the University of Wisconsin-Madison (UWMadison) and the University of Tokyo. Despite the...

Research uncovers a virus which infects a host that has a non-standard nuclear genetic code Among eukaryotes with modified nuclear genetic codes, viruses are unknown. Until now it had been believed that the modifications to the genetic code effectively prevented new viral infections. However, researchers have now reported the first example of a virus that can be shown to have crossed the boundary from organisms using the standard genetic code to those with an alternate genetic code....

Elusive Replication Machinery Of Flu Viruses Described
2012-11-23 09:27:03

Scripps Research Institute Scientists at The Scripps Research Institute (TSRI) have made a major advance in understanding how flu viruses replicate within infected cells. The researchers used cutting-edge molecular biology and electron-microscopy techniques to "see" one of influenza's essential protein complexes in unprecedented detail. The images generated in the study show flu virus proteins in the act of self-replication, highlighting the virus's vulnerabilities that are sure to be of...

The work is a key step toward 'universal' vaccine and therapies against flu A team led by scientists at The Scripps Research Institute and Crucell Vaccine Institute in the Netherlands describes three human antibodies that provide broad protection against Influenza B virus strains. The same team had previously reported finding broadly neutralizing antibodies against Influenza A strains. The isolation of the new broadly neutralizing antibodies, which was reported the journal Science's...
