ScienceDaily (Jan. 4, 2010) — Scientists in Vienna have developed a new technique for producing vaccines for H1N1 -- so-called swine flu -- based on insect cells. The research, published in the Biotechnology Journal, reveals how influenza vaccines can be produced faster than through the traditional method of egg-based production, revealing a new strategy for the fight against influenza pandemics.
"Recent outbreaks of influenza highlight the importance of a rapid and sufficient vaccine supply for pandemic and inter pandemic strains," said co-author Florian Krammer from the University of Natural Resources and Applied Life Science in Vienna. "However, classical manufacturing methods for vaccines fail to satisfy this demand."
Traditional influenza vaccines, which are produced in embryonated chicken eggs, can be manufactured in the quantities needed for seasonal strains of influenza. Yet because of limited egg supply this method may be insufficient in a pandemic scenario, such as the current H1N1 'swine flu' pandemic.
The team's new method turns to insect cell based technology to create recombinant influenza virus-like particles (VLPs), which resemble virus particles but lack the viral nucleic acid, so they are not infectious.
The Austrian team took just ten weeks to produce swine-origin pandemic H1N1 influenza VLPs for immunological study in mice. This shows that production of a mock-up vaccine is feasible in this time range, outcompeting conventional production methods which take months.
Using insect cells also bypasses the disadvantages of egg-based production, such as limited production capacity, allergic reactions to egg proteins and biosafety issues.
"Our work demonstrates that recombinant influenza virus-like particles are a very fast, safe and efficient alternative to conventional influenza vaccines and represents a significant new approach for newly emerging influenza strains like swine-origin H1N1 or H5N1," concluded Krammer.
"Virus-like particles will be one solution to tackle the biological variability of influenza pandemics," said journal editor Professor Alois Jungbauer. "Mutated strains can be quickly engineered. So in this respect the teams' work is an extremely valuable contribution to modern vaccine production."

In 2009 the world’s macrophotographers- both amateur and professional- continued to capture breathtaking images of the arthropod microscape. I’ve been bookmarking insect photos from around the web that catch my eye, and after spending some time this week reviewing the candidates I’ve selected nine favorites. Wow. These are the images from fellow photographers that most captured my imagination over the past year.

Last year’s picks are here.
Why is this important? Because the common fruit fly (Drosophila melanogaster) is one of the bugs that cannot survive freezing and the little creature just so happens to share much of the same genetic makeup as humans, therefore finding a way to freeze them for research purposes is a top priority for geneticists the world over (about 75 per cent of known human disease genes have a recognizable match in the genetic code of fruit flies).
And why the large microscope?
"It's the only one in the world that's set up for this kind of imaging on insects," says lead researcher Brent Sinclair of his team's use of the Advanced Photon Source (APS), located near Chicago, Illinois. The APS generates high-energy x-rays that allow Sinclair and his collaborators to film the formation and spread of ice in real time as the maggots freeze.
An assistant professor in Western's Department of Biology, Sinclair explains that the physical processes of ice formation seem to be consistent among species that do and don't survive freezing. However, it seems that the insects that survive freezing have some control over the process of ice formation. They freeze at consistently higher temperatures than those that don't.
Sinclair says this implies that the main adaptations required to survive freezing are at the cellular or biochemical level, rather than because of fundamental structural differences.
"We're comparing Chymomyza amoena, an insect native to Ontario that survives freezing, with Drosophila melanogaster, because they're very close relatives," says Sinclair. "The idea is to find the magic bullet which allows some bugs to survive freezing and some don't. That's the goal here."
The Western-led research was published in the journal PLoS ONE, an peer-reviewed, open-access resource from the Public Library of Science.
