Fighting flu in just two hours

As we approach midsummer, while most of us are enjoying days at the pool or beach and long evenings of grilling out, a few people have already begun the countdown to winter frosts and flu season.

For those in the latter group, SRxA’s Word on Health brings you good news!

Researchers from San Diego State University and Nebraska Medical Center have developed a synthetic protein known as EP67 that can fight off flu, in just two hours.

Until recently, EP67 had been used as an adjuvant for vaccines. When added to a vaccine, adjuvants help to activate the immune system. Which led scientists to wonder what effect the synthetic protein might have on its own?

Dr. Joy Phillips, lead author, said: “The flu virus is very sneaky and actively keeps the immune system from detecting it for a few days until you are getting symptoms. Our research showed that  introducing EP67 into the body within 24 hours of exposure to the flu virus caused the immune system to react almost immediately to the threat, well before your body normally would.”

EP67 is useful as a weapon against flu because it works on the immune system rather than the virus.  So it doesn’t matter which flu strain a patient becomes infected with.  If a new strain of flu or some other infectious disease appears, such as occurred with SARA and H1N1, EP67 could be useful as a tool even before the pathogen itself has been identified.

And even though this study concentrated on the benefits of EP67 for flu, researchers are hopeful that it might also be useful for combating other respiratory diseases and fungal infections.

Current tests are being done on laboratory animals, mainly mice, by infecting them with an influenza virus and then administering EP67 within 24 hours. They found that the treated mice did not get sick, while the untreated ones did.  Most mice infected with flu will lose approximately 20% of their body weight – this was the case with the untreated mice. The mice given EP67 lost just an average of 6%. Some mice were even given a lethal dose of flu virus, and then administered EP67 – none of them died.

All of this sounds so promising future studies are already planned to look at EP67’s effect on other pathogens and its functions within different types of body cells.

With this type of good news on the way, maybe we can all stop worrying about the winter and get back to enjoying summer before it’s gone!
