Its critical roles in the influenza virus life cycle and high sequence conservation suggest it should be a major target for therapeutic intervention. However, until very recently, functional studies and drug discovery targeting the influenza polymerase have been hampered by the lack of three-dimensional structural information. The influenza polymerase holds prospects for the development of anti-influenza therapeutics.Further reading: Influenza: Molecular VirologyFull range of books on microbiology at Microbiology Books (Source: Microbiology Blog: The weblog for microbiologists.)

The nucleoprotein (NP), the major protein component of RNPs, binds along the entire length of each genomic RNA segment at a 24-nt interval, forming the double-helical RNP structures found in mature viruses. The viral polymerase, consisting of PA, PB1, and PB2 subunits, binds to the two RNA termini of the RNP. As one of the most abundant proteins made in infected cells, influenza virus NP has essential roles in many important viral processes, including intracellular trafficking of the viral genome, viral RNA replication, viral genome packaging, and virus assembly. The recently determined crystal structures of two NP trimers show an overall fold and an exter...

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...

The supply will be good for 6 million to 7 million people, but the government expects about 250 million doses will be available over time. Of course, first priority goes to the most vulnerable, including healthcare workers, children, young adults and pregnant women. But don’t forget that you should still get a separate vaccine for the seasonal influenza. Neither one is going to protect you from the other virus. Now of the groups that the CDC highly recommends to get protection from the seasonal influenza virus, young adults were added on the list to get the swine flu shot. Don’t find this so strange. Even though this age group general...

About 39,000 residents in Beijing had been inoculated with A/H1N1 flu vaccine by Tuesday afternoon, with 14 cases of adverse reaction, an epidemic control expert said here Wednesday. The number of inoculated residents may be small compared to the total population, but China is gaining praise for being the first country to issue such a campaign, and acting as fast as it did. The Sinovac H1N1 vaccine was approved only on September 3rd, and already 40,000 residents have been vaccinated by this Tuesday afternoon. China has also gained reputation as having the most vigilant response against the swine flu pandemic....

The Foods and Drug Administration just approved four vaccines against the swine flu virus and it looks like the vaccines will be available in a little over a month. Swine Flu H1N1 Vaccine Soon Available Clinical trials proved that the vaccines are safe and only one shot is needed to gain immunity against the virus, and that’s really great news. Most vaccines work best when, and after the booster shot is given so this means that the swine flu vaccine works more quickly than other flu vaccines. So remember, if you’re one of the following people that are in higher priority to be immunized, ask your doctor or pediatrician about its availability. I already told my doctors to call us as soon they have the vaccine so I can...

The vaccines will be distributed nationally after the initial lots become available, which is expected within the next four weeks. “Today’s approval is good news for our nation’s response to the 2009 H1N1 influenza virus,” said Commissioner of Food and Drugs Margaret A.

When is the swine flu vaccine available? Should we get two shots – one for each flu virus? Should I just keep my child home this year? Infectious disease experts from Seattle Children’s Hospital posted this YouTube video to answer the many questions we parents have about the H1N1 influenza virus and its vaccine. Related to this, a preliminary study found that a single standard dose is sufficient to produce an immune response and another study found that protection occurs in 8-10 days after vaccination. The video is great resource and worth watching. I think most of your questions would be answered by this PSA...

But, it is newsworthy. According to a quote through the Examiner, Russian scientists secretly warned Prime Minister Putin about a “critical link” between the H1N1 Influenza virus and genetically modified amylopectin potatoes which are sold in Western countries as french fries. The report goes on to say that the genetically changed protease enzyme in the potatoes is so stored in the host cells (that’s us, humans who eat the fries) that our cells’ contact with an H1N1 virus creates an explosion in the viral envelope. The protein causes an acidic environment for the virus that explodes its envelope and releases the H1N1 RNA and core proteins into the host cell. Majority of cases of H1N1 infections hav...

The journalistic news of the week was probably the treatment of the outbreak with different outlets either downplaying the importance of the virus [Guardian] or preparing their readership for imminent doom [El Pais, ES] For those that are skeptic about the role of science in society (beyond that of fostering knowledge for cross words and collecting random facts) look no further than the specials put together by the likes of Science or Nature.

It is a virus that has a combination of gene segments from human, bird and swine viruses, and can potentially become infectious in humans that have no immunity to the new strain. Influenza viruses can change its make-up in one of two ways: Antigenic drift is a series of mutations that cause the virus to gradually evolve over time. Antigenic shift is an abrupt change in the surface antigen proteins that suddenly creates a new subtype of the virus. In the history of influenza outbreaks, antigenic shift is the cause behind pandemics in 1918 (Spanish Flu), 1957 (Asian Flu) and 1968 (Hongkong Flu) because the populations have not developed antibody protection against the virus.

Now it’s payback time: my granddaughter is bombarding me with daily questions, like “why do men wear pants and women wear skirts”? and other such questions for which there are no good straightforward answers. Here is a question I kept asking myself (in preparation for Rebecca’s inevitable question) and for which I didn’t have a satisfactory answer: why do the flu epidemics occur only in the winter?
