It is a multifunctional protein with two domains, a dsRNA binding domain (RBD) and an effector domain (ED) which interacts with various cellular proteins. Although, initially sequestration of dsRNA was considered the primary mechanism for countering IFN, subsequent studies have shown that the interactions of ED with various cellular proteins are likely involved. NS1 is shown to be a virulence determinant, especially in the highly pathogenic H5N1 viruses that are currently a threat for another influenza pandemic. Among various influenza virus strains, NS1 is relatively well conserved with major differences occurring in the linker region and the C-terminus, where...

These claimed the lives of approximately 50 million, 2 million and 1 million people respectively. Added to this is the annual death toll of 250,000 to 500,000 people worldwide with a further 3 to 4 million people suffering severe illness. These statistics make influenza an extremely important pathogen. In 1997 the alarming emergence of a new, highly pathogenic subtype, H5N1, which has a 50% mortality rate, provided a major impetus for renewed influenza research. However the battle against influenza is going to be difficult. Recently another subtype, H1N1, has emerged. This subtype causes a relatively mild infection in humans, however is highly transmittab...

The latter protein is believed to be an important determinant of influenza virus virulence. The absence of a full-length PB1-F2 protein has been suggested as one possible determinant for the low pathogenicity of the 2009 influenza H1N1 pandemic strain. Analysis of the evolutionary history of PB1-F2 suggests that it does not contribute significantly to viral fitness – the ability of the virus to replicate. PB1-F2 binds to mitochondria, leading to a release of cytochrome c and induction of apoptosis in CD8 T-cells and alveolar macrophages. The protein increases the severity of primary viral and secondary bact... virology blog blogs http://www.medworm.com/rss/comments.php?id=2743809 Fri, 28 Aug 2009 18:14:04 +0100 2743809 http://www.medworm.com/index.php?rid=2741085&cid=t_105017_139_f&fid=38879&url=http%3A%2F%2Ffeedproxy.google.com%2F%7Er%2FVirologyBlog%2F%7E3%2FvTenLq4wLTs%2F There are two glycoproteins embedded in the influenza viral membrane: the hemagglutinin (HA) and neuraminidase (NA). The NA, shown in yellow in the illustration, is an enzyme that removes sialic acids from the surface of the cell, so that newly formed virions can be released. The NA protein is composed of a box-like head attached to the viral membrane via a stalk. The length of the stalk may be an important determinant of the virulence of avian influenza H5N1 viruses. Examination of the sequence of all known influenza N1 NAs reveals that the proteins can be grouped into six classes depending on the length of the stalk region. The stalk regions of some NAs are intact, while others lack from 15 to 22 amino acids. In 2000, influenza H5N1 isolates from humans were identified with a deletion of... virology blog blogs http://www.medworm.com/rss/comments.php?id=2741085 Tue, 28 Jul 2009 13:00:14 +0100 2741085 http://www.medworm.com/index.php?rid=2386865&cid=t_105017_88_f&fid=38129&url=http%3A%2F%2Fsandnsurf.medbrains.net%2F2009%2F05%2Fwhat-do-you-mean-pandemic%2F Despite the cessation of ‘pig kissing frolicks‘ it looks as though the WHO will eventually declare that 2009 H1N1 influenza A (’swine flu’) has reached pandemic proportions (phase 6).

A new and potentially deadly infectious disease emerges somewhere in the world every year, threatening "devastating consequences" across the globe, warns the Lords intergovernmental organisations committee. Its report, published today, criticises Britain's "poorly coordinated" disease control systems. Reform of the World Health Organisation (WHO) is "essential", as the global health agency is "dysfunctional" and lacking the organisation and resources to curb a major outbreak, it says. The committee calls for new international disease surveillance systems in developing countries. The report says peers were given the following "sobering" advice by government ...

They recently suffered their 100th fatality from the deadly H5N1 virus. Containment is the best method we have to keep bird flu from mutating into a form that spreads easily from human-to-human. The BBC reports that the World Health Organization (WHO) says Indonesia will need more help in its battle against the disease. The virus is endemic in Java, Sumatra, Bali and southern Sulawesi with sporadic outbreaks reported from other areas, the FAO said. By June 2008, more than 2,000 surveillance and response teams will be active in more than 300 districts in areas of the country where the disease is endemic, Mr Domenech said. But that may not be enough. "Indonesia is facing an uphill battle against a virus that is d...

Humans also continue to catch and die from the virus although the much feared pandemic has not occured. Reuters collected these facts containg information from the OIE, WHO and Centers for Disease Control and Prevention. More than 30 countries have reported outbreaks in the past year, in most cases involving wild birds such as swans. The virus has killed at least 201 people since 2003, according to the WHO. Countries with confirmed human deaths are: Azerbaijan, Cambodia, China, Egypt, Indonesia, Iraq, Laos, Nigeria, Thailand, Turkey and Vietnam. In total, the virus is known to have infected 329 people since 2003, according to the WHO. Many of the dead are children and young adults. The WHO says that Vietnam and...

A mathematical analysis has confirmed that H5N1 avian influenza spread from person to person in Indonesia in April, U.S. researchers reported on Tuesday. They said they had developed a tool to run quick tests on disease outbreaks to see if dangerous epidemics or pandemics may be developing. Health officials around the world agree that a pandemic of influenza is overdue, and they are most worried by the H5N1 strain of avian influenza that has been spreading through flocks from Asia to Africa.

The problem is they don't when it will happen or how bad it will be. "The next pandemic will certainly happen," Margaret Chan told reporters following a forum on the need to improve international health security, noting it was impossible to guess when it might happen or how severe it might be. Since late 2003, the H5N1 strain of bird flu has prompted the slaughter of millions of birds across Asia and caused the deaths of more than 170 people worldwide, about one-third of them in Indonesia, according to WHO. The virus has been identified in Europe, Africa and the Middle East, in what Chan called an unprecedented spread. "We cannot let our guard down," Chan said. "My...

Vaccine May Treat Many Bird Flu Strains - Forbes.com: The vaccine measurably increased the levels of antibodies in 400 adults after they were given two shots. THe levels were high enough to give presumed protection against the strain of bird flu it was designed to work against. The more promising result is that it may protect against other strains. Other companies such as Novartis and Sanofi-Aventis has also seen cross-protection in their vaccines. What is interesting is the GSK is using a proprietary adjunct which can increase the number of doses by 10-fold. This would be vital if there were an epidemic.

If you saw the new Pandemic Severity Index provided by the government you know that is hardly the only problem a severe influenza outbreak could create. Meanwhile, in this country the new CDC guidelines that now rank pandemics in terms of categories 1 through 5, similar to hurricanes, are making the rounds in the media, and working its way through the government bureaucracy down to the states. The meat of the proposal? if there's a category 4 or 5 pandemic (H5N1 or some other), the schools in your town will close for up to three months, and large public gatherings will be canceled. That's because kids are a major vector in spreading flu and other respiratory diseases (ask any parent of a second grader or day c...

A Cat 5 flu would be far more devastating than a Cat 5hurricane. It would leave 1.8 million dead and it would shut down major cities for months. The new categories are part of a Pandemic Severity Index released as part of a new comprehensive strategy to deal with a severe influenza outbreak. You can see the Pandemic Severity Index graph on the right. You can see the new Community Strategy for Pandemic Influenza Mitigation from the government here on the PandemicFlu.gov website.

The world is years away from stamping out bird flu in poultry, and the threat of a human pandemic will remain until it does, the head of the World Health Organization (WHO) said on Monday. Addressing the U.N. agency's 34-state executive board, WHO Director-General Margaret Chan said that in the past three years the H5N1 bird flu virus had proven virulent. "As long as the virus continues to circulate in birds, the threat of a pandemic will persist. The world is years away from control in the agricultural sector," she said. Chan warned health experts and physicians to remain vigilant. "Influenza viruses are notoriously sloppy, unstable a...

The deadly H5N1 strain of avian influenza is making a seasonal resurgence in Asia and could easily spread to Europe again this year, the World Health Organisation warned on Sunday. The alarm follows four human deaths in Indonesia in the last five days, the first human case in China for six months (though the infected man has since recovered) and new poultry outbreaks in Vietnam - despite a huge campaign against it - and northern Nigeria. "We are convinced that we're in a repeat of last year and the year before when the virus began to get very active again [in the northern hemisphere winter] and spread from Asia into the Middle East and beyond," said Peter Cordingl...
