Gene therapy protected mice influenza virus pandemic...

A dose of adeno-associated virus, which acts as an activator of the antibody that neutralizes the influenza pandemic strains in the nostrils of mice and ferrets (rodents), protected them from the flu.

A study by specialists at the University of Pennsylvania, in the United States (U.S.) revealed on Wednesday that a genes-related therapy protected mice against different influenza viruses that have caused pandemics such as the Spanish flu, that in the early twentieth century killed about 50 million people.

The authors of this study published in the journal Science Translational Medicine explained that a dose of adeno-associated virus, which acts as an activator of the antibody that neutralizes the influenza pandemic strains in the nostrils of mice and ferrets, protected the rodents from influenza.

Adeno-associated viruses were used to transfer genes that occur naturally in humans and primates, and are not pathogenic.

The analysis showed that the mice were completely protected from H5N1 and H1N1, highly pathogenic and responsible for deadly flu.

These strains were isolated from samples associated with various historical pandemics, including the 1918 and 2009.

"The experiments described in this study demonstrate the effectiveness of this approach in animals, which could be used to fight any pandemic or bioterrorism agent, for which antibodies are available and can be easily isolated," said James Wilson, of the University of Pennsylvania, author of the study.

The expert added that "the development of this genetic technology has become even more urgent with the recent surge in China's H7N9 bird flu, deadly to humans".

Meanwhile, Maria Lambris, University of Pennsylvania, found that the novelty of this approach is the use of adeno-associated virus to achieve a simple and effective prophylactic vaccine in the nasal passages.

Researchers in the US used a gene therapy technique which worked well against the H5N1 and H1N1 flu virus.

Gene therapy is a new technique which uses genes to treat or prevent disease.

The idea behind it is that doctors can tackle a disorder by inserting a gene into a patient's cells instead of using drugs or surgery.

Investigators at the Perelman School of Medicine, University of Pennsylvania, used a liquid to place a gene replicating an antibody known to be effective against flu into the noses of mice and ferrets, and found it gave them protection against lethal strains of the virus.

The strains were isolated from samples associated with an infamous flu pandemic in 1918 and another in 2009.

One of the scientists, James Wilson, said: "The experiments described in our paper provide critical proof-of-concept in animals about a technology platform that can be deployed in the setting of virtually any pandemic or biological attack for which a neutralising antibody exists or can be easily isolated.

"Further development of this approach for pandemic flu has taken on more urgency in light of the spreading infection in China of the lethal bird strain of H7N9 virus in humans."

The technique establishes broad-based efficacy against a wide range of flu strains.

The treatment was tested in mice that were exposed to lethal quantities of three strains of H5N1 and two strains of H1N1, all of which have been associated with historic human pandemics (including the infamous H1N1 1918).

The flu virus rapidly replicated in untreated animals all of which needed to be put down.

THE Davao Adventist Hospital is now offering services for autologous stem cell therapy.

Marketing officer Kim Endrei Go said the therapy is the first in Davao City and an alternative treatment for degenerative diseases of joints and bones caused by sports injuries and chronic pains.

Go said the treatment allows the patient to continue the normal routine even after the treatment. He said the therapy is non-surgical and has a healing period of only three days.

The modalities in extracting stem cells in the therapy are either through the Platelet Rich Plasma (PRP) and through Bone Marrow Aspiration Concentrate.

Go said autologous means that the stem cells will be extracted from the patient himself and will be regenerated through an equipment.

The hospital uses the Harvest technologies from the United States which introduced the SmartPrePtm2.

SmartPrePtm2 is used to redefine platelet concentrate systems. Its latest innovation will further expand and enhance the use of autologous bioactive proteins as well as help optimize the condition for healing.

Go said that the therapy session depends on the severeness of the patient's condition. He added that most patients had 3 sessions but some had once or twice.

He said the technology was first practice in their Cebu branch and is now adopted for Davao. He said that in Cebu there about almost 90 treatments since November last where it was launched.

Each session costs P80,000 where about 60 cc of platelet and stem cells will be collected from the patient.

Studies on lab animals have shown early success in a type of gene therapy that may prevent the spread of pandemic flu, including historic lethal strains from 1918 and 2009, researchers said Wednesday.

The method developed at the University of Pennsylvania School of Medicine delivered a broadly neutralizing flu antibody into the nasal passages of ferrets and mice, protecting them against potentially lethal flu.

The research is still in its initial stages, but could offer a new tool against influenza infections which kill 500,000 people globally each year, scientists said.

A single dose appeared to protect mice for as long as nine months against a range of flu strains, including three strains of H5N1, a deadly bird flu, and and two strains of H1N1, known widely as the "swine flu" that emerged in 2009.

Typically, influenza viruses evolve so rapidly that a new vaccine is created each year, offering only limited protection against the flu which can be lethal particularly in the elderly and those with weak immune systems.

The research published in the journal Science Translational Medicine did not experiment with the latest form of bird flu to emerge from China, H7N9, which has killed 37 of the 132 people infected since March.

According to a separate study in The Lancet on Tuesday, some H7N9 bird flu patients have already been found to be resistant existing antivirals, likely as a result of treatment with Tamiflu.

"The experiments described in our paper provide critical proof-of-concept in animals," said lead researcher James Wilson, of the department of pathology and laboratory medicine at the University of Pennsylvania.

"Further development of this approach for pandemic flu has taken on more urgency in light of the spreading infection in China of the lethal bird strain of H7N9 virus in humans."

Scientists cloned a gene that encodes an antibody that works against many strains of flu, then engineered cells that line the nasal passages and express a broadly neutralizing antibody that wards off flu.

Credit: Public Domain Photo

(Phys.org) Honey bees don't start out knowing how to find flowers or even how to get around outside the hive. Before they can forage, they must learn how to navigate a changing landscape and orient themselves in relation to the sun.

In a new study, researchers report that a regulatory gene known to be involved in learning and the detection of novelty in vertebrates also kicks into high gear in the brains of honey bees when they are learning to how to find food and bring it home.

Activity of this gene, called Egr, quickly increases in a region of the brain known as the mushroom bodies whenever bees try to find their way around an unfamiliar environment, the researchers observed. This gene is the insect equivalent of a transcription factor found in mammals. Transcription factors regulate the activity of other genes.

The researchers found that the increased Egr activity did not occur as a result of exercise, the physical demands of learning to fly or the task of memorizing visual cues; it increased only in response to the bees' exposure to an unfamiliar environment. Even seasoned foragers had an uptick in Egr activity when they had to learn how to navigate in a new environment.

"This discovery gives us an important lead in figuring out how honey bees are able to navigate so well, with such a tiny brain," said Gene Robinson, a professor of entomology and neuroscience and director of the Institute for Genomic Biology at the University of Illinois. "And finding that it's Egr, with all that this gene is known to do in vertebrates, provides another demonstration that some of the molecular mechanisms underlying behavioral plasticity are deeply conserved in evolution."

Washington, May 29 (IANS) The spectacular white coat of white tigers are caused by a single change in a known pigment gene, a study has found.

The research, to be published in the June issue of Current Biology, might help end decades of speculation that the trait is a genetic defect, reported Xinhua.

Researchers from China's Peking University mapped the genomes of a family of 16 tigers living in Chimelong Safari Park in southern China, including both white and orange individuals. They then sequenced the whole genomes of each of the three parents in the family.

In the end, the researchers found the white tiger carries a variant of a pigment gene called SLC45A2, which had already been associated with light colouration in modern Europeans and in other animals, including horses, chickens, and fish.

The variant of the gene primarily inhibits the synthesis of red and yellow pigments but has little to no effect on black, which explains why white tigers still show characteristic dark stripes, the researchers said.

"The genetic study solved the mystery about what makes those tigers white," Luo Shujin, author of the study said in an email interview with Xinhua. "It shows the white tiger morph is a naturally occurring feature and should be considered a part of the genetic diversity of tigers that is worth conserving."

White tigers were first discovered in the Indian jungle as a variant of Bengal tigers

but have now disappeared from the wild, Luo said.

Luo said that many white tigers in captivity are inbred in order to maintain the white coat trait and consequently suffer some health problems such as crossed eyes, leading to the controversial speculation that the white tiger mutation is perhaps a genetic defect.

For $99, the company 23andMe can generate all of your basic DNA testing information: ancestral origins, disease predisposition and even if you are more likely to sneeze under a bright light. But it is the only company in the U.S. that can tell you if you carry a gene variant that makes you more likely to develop Parkinsons Disease.

Like many other companies in Silicon Valleys thriving biotechnology scene, 23andMe holds a patent for a human gene. Anyone who wishes to find if they carry the Parkinsons-related gene must use 23andMes testing kit. In fact, thats how Googles Sergey Brin, who also happens to be married to 23andMe co-founder AnneWojcicki, found out he has the gene.

It is a scenario that is common across the industry; companies pour money into research and then rely on patents to protect their discoveries and diagnostic tools, and to generate revenue. More than 40,000 patents cover 41 percent of the human genome, according to a Cornell University study released in March.

That could change this year. A case currently before the Supreme Court asks the justices to consider if a human gene should be patentable. At the center of the case is Myriad, a Utah company that holds two patents for genes linked to breast and ovarian cancer. Supporters say intellectual property protection makes it possible for companies to confidently sink millions into research. They also say the patents are issued for the minute segment of DNA that makes up a gene, which researchers must extract from a much larger strand. Once it is removed from the body and chemically altered, it becomes distinct.

They were never available to the world until Myriads scientists applied their inventive faculties to a previously undistinguished mass of genetic matter and created a new chemical entity, Myriad says in a Supreme Court brief.

Opponents say it is still the same gene, and isolating it does not constitute a patentable invention. They also say being able to patent genes makes genes inaccessible to research and raises testing costs for patients.I see Myriads claim that a gene should be patentable because they isolated and purified it away from its natural context to have no more validity than claiming that if you cut a leaf off a tree you have now created a new thing and should be able to patent it, said Robert Nussbaum, head of genomic medicine at University of California-San Francisco and founder of an open-access gene database. I see a gene that is isolated or patented as being a discovery of something in nature, not an invention.

The justices are expected to rule before the end of their term in June.

May 29, 2013 Experimental genetic techniques may one day provide plastic and reconstructive surgeons with an invaluable tool -- the ability to promote growth of the patient's own tissues for reconstructive surgery. A review of recent progress toward developing effective gene therapies for use in "regenerative surgery" appears in the June issue of Plastic and Reconstructive Surgery, the official medical journal of the American Society of Plastic Surgeons (ASPS).

Over the past ten years, researchers have developed several promising gene therapy techniques to grow skin, bone, and other tissues for reconstructive surgery. But they still face many challenges in developing gene-based approaches that can make the leap from the research lab to the operating room, according to the review by Dr. Giorgio Giatsidis and colleagues of Padua University Hospital, Italy.

Gene Therapy Approaches Studied for 'Almost Every Tissue'

Dr. Giatsidis and coauthors reviewed the state of the art in research on gene therapy techniques for treatment of local disorders and injuries -- the first such review in more than a decade. They found studies using gene therapy to promote the growth of "almost every different tissue" for use in regenerative surgery. "Gene therapy may represent a leading strategy to develop more efficient regenerative surgical treatments for numerous clinical needs," they write.

Gene therapy has the potential to provide reconstructive surgeons with a new approach to solving one of their most difficult problems: the lack of adequate tissues to correct deformities of a specific area or structure. For example, in patients with relatively small burns, plastic and reconstructive surgeons have designed a wide range of skin flaps for use in transferring healthy tissue to the burned area.

But for patients with burns involving larger areas, the lack of suitable tissues for coverage may severely limit the reconstructive options. Using gene techniques to promote growth of specific types of tissues would be a major step forward in the ability to perform truly regenerative surgery.

But Translation from Lab to OR Poses Many Challenges

Several research groups are pursuing gene therapy approaches to regenerate skin, such as using genes to control expression of growth factors involved in skin healing. One small study reported promising results with tissue-engineered products to promote healing of diabetic skin ulcers.

Researchers are also targeting growth factors involved in new bone formation, with promising results in techniques using transplantation of genetically modified donor bone. One study reported clinical benefits using gene therapy to regenerate joint cartilage in patients with rheumatoid arthritis. Techniques to promote healing of tendons, regeneration of injured nerves, and growth of skin flaps for reconstructive surgery are all being explored.

But despite progress in all of these areas, translating experimental gene therapy methods into regenerative surgery techniques for use in the operating room will remain a difficult challenge. Even after the technical problems are addressed, more work will be needed to develop regenerative surgery techniques that are productive and cost-effective.

New Rochelle, NY, May 29, 2013YouTube has more than 10 million unique users a month who are younger than 18 years of age, making it an ideal online environment in which to study the impact of various media content and peer feedback on adolescents. A series of experiments were designed to test the effectiveness of using YouTube to present controlled media content and peer comments to teens, and to measure their preferences and moral judgments. The results are presented in Cyberpsychology, Behavior, and Social Networking, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available free on the Cyberpsychology, Behavior, and Social Networking website.

In "YouTube as Research ToolThree Approaches," Elly Konijn, Jolanda Veldhuis, and Xanthe Plaisier, VU University Amsterdam, The Netherlands, developed experimental materials to post on YouTube. For example, they presented content related to female models and body weight and included prepared peer comments. They then measured how the teens in the study reacted to and interacted with the content. The aim of this experiment was to study the influences of peer feedback and body perception and to identify possible ways to counteract negative influences.

"The authors have done a good job in demonstrating how YouTube can be utilized for systematic research," says Brenda K. Wiederhold, PhD, MBA, BCIA, Editor-in-Chief of Cyberpsychology, Behavior, and Social Networking, from the Interactive Media Institute, San Diego, CA. "This research can also be extended to other topics as well as to other social networking tools, such as Facebook and Twitter."

New Rochelle, NY, May 29, 2013A novel, targeted approach to chemotherapy that makes ovarian cancer cells more susceptible to the cytotoxic effects of an antitumor drug may offer a safer, more effective treatment option for this often deadly form of cancer. The research and results are published in Nucleic Acid Therapeutics, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers (http://www.liebertpub.com). The article is available on the Nucleic Acid Therapeutics website (http://www.liebertpub.com/nat).

Ovarian cancer is usually diagnosed at an advanced stage of disease, and although most patients initially respond to conventional chemotherapeutic agents, the cancer typically recurs and the overall survival rate is poor. Furthermore, current chemotherapeutics for ovarian cancer are nonspecific and generally toxic causing debilitating side effects. More effective and specific agents are needed that target ovarian cancer cells and inhibit their ability to reproduce.

Sibaji Sarkar and Douglas Faller, Boston University School of Medicine (Boston, MA), successfully advanced their research to develop anti-tumor drugs comprised of nucleic acids, the building blocks of DNA. They had previously shown that so-called "GT-oligos" (which target and bind to nucleic acid sequences present in regions found at the ends of chromosomes, called telomeres) can trigger cell death in certain types of cancer cells, including ovarian, pancreatic, and prostate cancer. However not all cancer cells in these and other tumor types are susceptible to the effects of GT-oligos.

In the current study the authors take this work a step further and demonstrate a novel method to sensitive resistant ovarian cancer cells to this targeted chemotherapeutic approach. They describe the details of this strategy and the potential to apply this technique more broadly to treat other types of epithelial cancers in the article " Telomere-Homologous G-rich Oligonucleotides Sensitize Human Ovarian Cancer Cells to TRAIL-Induced Growth Inhibition and Apoptosis." (http://online.liebertpub.com/doi/full/10.1089/nat.2012.0401)

"The devastating mortality rate from ovarian cancer has not changed since the 'War on Cancer" was declared in 1971," says Executive Editor Fintan Steele, PhD, SomaLogic, Inc., Boulder, CO. "We need to improve both early diagnosis and find novel treatments. The work by Sarker and Faller provides a new and promising approach for treatment of this particularly difficult form of cancer."

In one of the first successful attempts at genetically engineering mosquitoes, HHMI researchers have altered the way the insects respond to odors, including the smell of humans and the insect repellant DEET. The research not only demonstrates that mosquitoes can be genetically altered using the latest research techniques, but paves the way to understanding why the insect is so attracted to humans, and how to block that attraction.

The time has come now to do genetics in these important disease-vector insects. I think our new work is a great example that you can do it, says Leslie Vosshall, an HHMI investigator at The Rockefeller University who led the new research, published May 29, 2013 in the journal Nature.

By disrupting a single gene, we can fundamentally confuse the mosquito from its task of seeking humans. Leslie B. Vosshall

In 2007, scientists announced the completion of the full genome sequence of Aedes aegypti, the mosquito that transmits dengue and yellow fever. A year later, when Vosshall became an HHMI investigator, she shifted the focus of her lab from Drosophila flies to mosquitoes with the specific goal of genetically engineering the insects. Studying mosquitoes appealed to her because of their importance as disease carriers, as well as their unique attraction to humans.

Vosshalls first target: a gene called orco, which her lab had deleted in genetically engineered flies 10 years earlier. We knew this gene was important for flies to be able to respond to the odors they respond to, says Vosshall. And we had some hints that mosquitoes interact with smells in their environment, so it was a good bet that something would interact with orco in mosquitoes.

Vosshalls team turned to a genetic engineering tool called zinc-finger nucleases to specifically mutate the orco gene in Aedes aegypti. They injected the targeted zinc-finger nucleases into mosquito embryos, waited for them to mature, identified mutant individuals, and generated mutant strains that allowed them to study the role of orco in mosquito biology. The engineered mosquitoes showed diminished activity in neurons linked to odor-sensing. Then, behavioral tests revealed more changes.

When given a choice between a human and any other animal, normal Aedes aegypti will reliably buzz toward the human. But the mosquitoes with orco mutations showed reduced preference for the smell of humans over guinea pigs, even in the presence of carbon dioxide, which is thought to help mosquitoes respond to human scent. By disrupting a single gene, we can fundamentally confuse the mosquito from its task of seeking humans, says Vosshall. But they dont yet know whether the confusion stems from an inability to sense a bad smell coming from the guinea pig, a good smell from the human, or both.

Next, the team tested whether the mosquitoes with orco mutations responded differently to DEET. When exposed to two human armsone slathered in a solution containing 10 percent DEET, the active ingredient in many bug repellants, and the other untreatedthe mosquitoes flew equally toward both arms, suggesting they couldnt smell the DEET. But once they landed on the arms, they quickly flew away from the DEET-covered one. This tells us that there are two totally different mechanisms that mosquitoes are using to sense DEET, explains Vosshall. One is whats happening in the air, and the other only comes into action when the mosquito is touching the skin. Such dual mechanisms had been discussed but had never been shown before.

Vosshall and her collaborators next want to study in more detail how the orco protein interacts with the mosquitoes odorant receptors to allow the insects to sense smells. We want to know what it is about these mosquitoes that makes them so specialized for humans, she says. And if we can also provide insights into how existing repellants are working, then we can start having some ideas about what a next-generation repellant would look like.

Gene therapies for regenerative surgery are getting closer, says review in PRS

ARLINGTON HEIGHTS, IL--(Marketwired - May 29, 2013) - Experimental genetic techniques may one day provide plastic and reconstructive surgeons with an invaluable tool -- the ability to promote growth of the patient's own tissues for reconstructive surgery. A review of recent progress toward developing effective gene therapies for use in "regenerative surgery" appears in the June issue of Plastic and Reconstructive Surgery, the official medical journal of the American Society of Plastic Surgeons (ASPS).

Over the past ten years, researchers have developed several promising gene therapy techniques to grow skin, bone and other tissues for reconstructive surgery. But they still face many challenges in developing gene-based approaches that can make the leap from the research lab to the operating room, according to the review by Dr. Giorgio Giatsidis and colleagues of Padua University Hospital, Italy.

Gene Therapy Approaches Studied for 'Almost Every Tissue'Dr. Giatsidis and coauthors reviewed the state of the art in research on gene therapy techniques for treatment of local disorders and injuries -- the first such review in more than a decade. They found studies using gene therapy to promote the growth of "almost every different tissue" for use in regenerative surgery. "Gene therapy may represent a leading strategy to develop more efficient regenerative surgical treatments for numerous clinical needs," they write.

Gene therapy has the potential to provide reconstructive surgeons with a new approach to solving one of their most difficult problems: the lack of adequate tissues to correct deformities of a specific area or structure. For example, in patients with relatively small burns, plastic and reconstructive surgeons have designed a wide range of skin flaps for use in transferring healthy tissue to the burned area.

But for patients with burns involving larger areas, the lack of suitable tissues for coverage may severely limit the reconstructive options. Using gene techniques to promote growth of specific types of tissues would be a major step forward in the ability to perform truly regenerative surgery.

But Translation from Lab to OR Poses Many Challenges Several research groups are pursuing gene therapy approaches to regenerate skin, such as using genes to control expression of growth factors involved in skin healing. One small study reported promising results with tissue-engineered products to promote healing of diabetic skin ulcers.

Researchers are also targeting growth factors involved in new bone formation, with promising results in techniques using transplantation of genetically modified donor bone. One study reported clinical benefits using gene therapy to regenerate joint cartilage in patients with rheumatoid arthritis. Techniques to promote healing of tendons, regeneration of injured nerves, and growth of skin flaps for reconstructive surgery are all being explored.

But despite progress in all of these areas, translating experimental gene therapy methods into regenerative surgery techniques for use in the operating room will remain a difficult challenge. Even after the technical problems are addressed, more work will be needed to develop regenerative surgery techniques that are productive and cost-effective.

"After two decades, regenerative surgery is an adolescent looking forward to growing up," Dr. Giatsidis and coauthors write. "Despite extensive preclinical approaches, translation of gene therapy strategies into clinical trials is still a difficult and expensive process."

So far, the studies of diabetic ulcers and rheumatoid arthritis mentioned above are the only methods to show evidence of clinical effectiveness in human patients. "Even so," the authors add, "cutting-edge gene therapy-based strategies in reconstructive procedures [are close] to setting valuable milestones for development of efficient treatments in a growing number of local diseases and injuries."

Gene Therapies for Regenerative Surgery Are Getting Closer, Says Review in Plastic and Reconstructive Surgery

Scientists may have discovered a new weapon in the war against influenza, according to a study.

Researchers in the US used a gene therapy technique which worked well against the H5N1 and H1N1 flu virus. Gene therapy is a new technique in which doctors can tackle a disorder by inserting a gene into a patient's cells instead of using drugs or surgery.

Investigators at the Perelman School of Medicine, University of Pennsylvania, used a liquid to place a gene replicating an antibody known to be effective against flu into the noses of mice and ferrets, and found it gave them protection against lethal strains of the virus.

In the study, published in the journal Science Translational Medicine, the strains were isolated from samples associated with an infamous flu pandemic in 1918 and another in 2009.

One of the scientists, James Wilson, said: "The experiments described in our paper provide critical proof-of-concept in animals about a technology platform that can be deployed in the setting of virtually any pandemic or biological attack for which a neutralising antibody exists or can be easily isolated.

"Further development of this approach for pandemic flu has taken on more urgency in light of the spreading infection in China of the lethal bird strain of H7N9 virus in humans."

The technique establishes broad-based efficacy against a wide range of flu strains.

The treatment was tested in mice that were exposed to lethal quantities of three strains of H5N1 and two strains of H1N1, all of which have been associated with historic human pandemics (including the infamous H1N1 1918).

The flu virus rapidly replicated in untreated animals all of which needed to be put down. However, pre-treatment with the liquid containing the gene virtually shut down virus replication and provided complete protection against all strains of flu in the treated animals.

One of the scientists, Maria Limberis, said: "The novelty of this approach is that we're ... delivering the prophylactic vaccine to the nose in a non-invasive manner, not a shot like conventional vaccines that passively transfer antibodies to the general circulation."

Study found coaxing cells in the nose to make super antibodies protected mice and ferrets from pandemic strains

WebMD News from HealthDay

WEDNESDAY, May 29 (HealthDay News) -- Gene therapy that turns cells in the nose into factories that crank out super antibodies against the flu protected mice and ferrets against lethal doses of several pandemic strains of the virus.

If the approach works in humans, it could offer several important advantages over flu vaccines, said study author Dr. James Wilson, a professor of pathology and laboratory medicine at the University of Pennsylvania, in Philadelphia.

Because the therapy can be made ahead of time and fights many different strains, it might give doctors a faster way to thwart flu pandemics.

Currently, doctors race to identify dangerous new types of flu. They then have to develop a vaccine that targets the new strain. The vaccine is then grown in chicken eggs and tested for safety. It takes between three and six months to manufacture large quantities of vaccines against the flu.

"By the time we realize it's a potential pandemic, it's too late," Wilson said. "The timeliness of deploying the seasonal flu vaccine approach for pandemics is not the best way to go."

Vaccines, which prime the body to remember to attack incoming pathogens, also don't do the best job of protecting people who have diminished immune function, such as seniors and those with chronic health problems.

Gene Therapy May Protect Against Flu Pandemics

Recommendation and review posted by Bethany Smith

PHILADELPHIA Researchers at the Perelman School of Medicine, University of Pennsylvania have developed a new gene therapy to thwart a potential influenza pandemic. Specifically, investigators in the Gene Therapy Program, Department of Pathology and Laboratory Medicine, directed by James M. Wilson, MD, PhD, demonstrated that a single dose of an adeno-associated virus (AAV) expressing a broadly neutralizing flu antibody into the nasal passages of mice and ferrets gives them complete protection and substantial reductions in flu replication when exposed to lethal strains of H5N1 and H1N1 flu virus. These strains were isolated from samples associated from historic human pandemics one from the infamous 1918 flu pandemic and another from 2009.

Wilson, Anna Tretiakova, PhD, Senior Research Scientist, Maria P. Limberis, PhD, Research Assistant Professor, all from the Penn Gene Therapy Program, and colleagues published their findings online this week in Science Translational Medicine ahead of print. In addition to the Penn scientists, the international effort included colleagues from the Public Health Agency of Canada, Winnipeg; the University of Manitoba, Winnipeg; and the University of Pittsburgh. Tretiakova is also the director of translational research, and Limberis is the director of animal models core, both with the Gene Therapy Program.

The experiments described in our paper provide critical proof-of-concept in animals about a technology platform that can be deployed in the setting of virtually any pandemic or biological attack for which a neutralizing antibody exists or can be easily isolated, says Wilson. Further development of this approach for pandemic flu has taken on more urgency in light of the spreading infection in China of the lethal bird strain of H7N9 virus in humans.

Influenza infections are the seventh leading cause of death in the United States and result in almost 500,000 deaths worldwide per year, according to the Centers for Disease Control. The emergence of a new influenza pandemic remains a threat that could result in a much loss of life and worldwide economic disruption.

There is also interest by the military in developing an off-the-shelf prophylactic vaccine should soldiers be exposed to weaponized strains of infectious agents in biologic warfare.

Human antibodies with broad neutralizing activity against various influenza strains exist but their direct use as a prophylactic treatment is impractical. Now, yearly flu vaccines are made by growing the flu virus in eggs. The viral envelope proteins on the exterior, namely hemagglutinin, are cleaved off and used as the vaccine, but vary from year to year, depending on what flu strains are prevalent. However, high mutation rates in the proteins result in the emergence of new viral types each year, which elude neutralization by preexisting antibodies in the body (specifically specific receptor binding sites on the virus that are the targets of neutralizing antibodies).

This approach has led to annual vaccinations against seasonal strains of flu viruses that are predicted to emerge during the upcoming season. Strains that arise outside of the human population, for example in domestic livestock, are distinct from those that normally circulate in humans, and can lead to deadly pandemics.

These strains are also not effectively controlled by vaccines developed to human strains, as with the 2009 H1N1 pandemic. The vaccine development time for that strain, and in general, was not fast enough to support vaccination in response to an emerging pandemic.

Knowing this, the Penn team proposed a novel approach that does not require the elicitation of an immune response, which does not provide sufficient breadth to be useful against any strain of flu other than the one for which it was designed, as with conventional approaches.

The Penn approach is to clone into a vector a gene that encodes an antibody that is effective against many strains of flu and to engineer cells that line the nasal passages to express this broadly neutralizing antibody, effectively establishing broad-based efficacy against a wide range of flu strains.
