and the Proceedings of the National Academy of Sciences (PNAS) provide a promising new target for antiviral therapies.

Most antiviral drugs work by deactivating viral proteins but viruses often evolve and become drug resistant.

avoid being destroyed by the body s antiviral response. The findings which appear in PLOS Pathogens provide knowledge that could help researchers treat the disease more effectively.

and infects cells it induces the production and release of interferonsâ proteins that raise the body s antiviral defense mechanisms.

This attaches to proteins in the cell that help in the production of antiviral proteins in response to interferons.

and out of the cell nucleus. The map reveals that the viral protein takes away the host protein s ability to carry an important immune signal into the nucleus. This signal helps activate the immune system s antiviral defenses

and activates the genes for hundreds of proteins involved in antiviral responses##Leung says.####But when VP24 is attached to some of these transporters STAT1 can t get into the nucleus.##The study shows that VP24 s action specifically prevents STAT1 transport.

or potential antiviral drugs could interfere with this process, Tamm says. ou have these contacts that need to be made to make the clenching of the fist happenf you could find a molecule that throws a wrench into the gears of that mechanism,

Despite the worldwide use of vaccination and other antiviral interventions, the flu virus remains a persistent threat to human health.

mice treated with a compound that inhibits PGE2 showed enhanced antiviral immunity and produced better survival rates following infection with a lethal dose of the flu virus compared with untreated mice. revious studies produced conflicting results due to the inhibition of all prostanoids

Divangahi says. ur findings suggest that different prostaglandins have different roles in antiviral immunity and that specific inhibition of PGE2 will be an effective therapy against influenza viral infection by boosting immune responses. i

That protein could be a good target for antiviral drugs, researchers suggest. Better antiviral drugs could help the millions of people annually infected by flu,

which kills up to 500,000 people each year. When an influenza virus infects a human cell, it uses some of the host cellular machinery to make copies of itself,

such as inhibiting the host synthesis of interferon, a key antiviral protein, Krug says. t means that

FAST-SPREADING EPIDEMICS The need for new antiviral drugs against the influenza virus is great.

antiviral drugs play an important role in fast-spreading epidemics. Yet Influenza a viruses are developing resistance to antiviral drugs currently in use.

Krug and his team discovered that the viral NS1 protein is associated often, or bound together, with the host DDX21 protein in infected human body cells.

which chitin is being used to cheaply produce a currently very-expensive source of antiviral drugs.

Many presently-used antiviral drugs are derived from N acetylneuraminic-acid acid, also known as NANA. The substance can synthesized

the research may also hold promise for the development of new antiviral drugs and better delivery mechanisms for gene therapy.

This would represent a quantum leap in antiviral therapy, says Fussenegger, who was involved not in the study.

as well as antiviral therapy to combat already-existing infections, particularly challenging",says Dr. Grant Hansman, a virologist who leads the CHS Research Group on Noroviruses at the German Cancer Research center (Deutsches Krebsforschungszentrum, DKFZ) and Heidelberg University.

this could be a very promising lead in developing norovirus antiviral therapy. This could be especially beneficial to immunosuppressed individuals such as cancer patients.

However, if he or she has the option of receiving an antiviral to eliminate the infection,

This would represent a quantum leap in antiviral therapy, says Fussenegger, who was involved not in the study.

Scientists predict that this finding might lead to a new class of antiviral drugs capable of targeting a range of different infections, The british Science Festival heard last week.

'By understanding genetic variants like this we can start to think about broad-spectrum antivirals that hit a whole range of viruses,

This could lead to a broad-spectrum antiviral, though it would work by altering human cells rather than targeting the virus directly,

This would represent a quantum leap in antiviral therapy, said Fussenegger, who was involved not in the study.

By borrowing an antiviral mechanism called CRISPR-Cas9 from bacteria, they created an easy way to tweak the genetic information in a cell nucleus. This has implications for medicine and agriculture.

It might also be used to produce new classes of antiviral treatment, and thus curb infectious disease.

That alarm sets off an inflammatory cascade that induces antiviral molecules, including a family of secreted proteins called interferons.

This would represent a quantum leap in antiviral therapy, says Fussenegger, who was involved not in the study.

#Experimental treatment regimen effective against HIV PROTEASE inhibitors are a class of antiviral drugs that are used commonly to treat HIV, the virus that causes AIDS.

Originally discovered as an antiviral system in bacteria, CRISPR/Cas9 is one of the hottest topics in genetic research today.

The findings from the University of Chicago and the Massachusetts institute of technology could bolster efforts to develop the next generation of antiviral treatments.

This feature also helps them become resistant to antiviral drugs. But scientists have developed therapeutic antiviral agents for HIV

Hepatitis C, and influenza using a strategy called lethal mutagenesis. This strategy seeks to extinguish viruses by forcing their already high mutation rates above an intolerable threshold.

But together their research teams were able to fruitfully undertake one of the first 2d infrared spectroscopic studies of the therapeutic mechanism of an antiviral drug."

Despite the strong antiviral immune response seen in the new study, Holtzman and his colleagues reported no evidence of autoimmune disease in these mice.

and absence of destructive autoimmunity could be that the researchersstrategy did not involve increasing the amount of interferon, the first step of this important antiviral signaling cascade.

Elledge says the approach his team has developed is limited not to antiviral antibodies. His own lab is also using it to look for antibodies that attack a body's own tissue in certain autoimmune diseases that are associated with cancer.

Among other things, so-called'interferons'play an important role in antiviral defense. These are special proteins
