Are there any viruses that are beneficial to the human race?

Some of the viruses infecting humans are indeed capable of causing severe and often lethal diseases, but other viruses can be manipulated to be beneficial to human health. These viruses offer the potential to cure cancer, correct genetic disorders, or fight pathogenic viral by: 7. Jun 22,  · Thanks to their unique ability to worm into DNA, viruses can be used to inject genes into cells, which can reverse some genetic diseases. For example, some viruses have been able to cure hemophilia, a blood disorder that prevents clotting. Viruses have also helped illuminate how the human mind works, using a technique called optogenetics.

Her review of the current literature on beneficial viruses appeared ahead of print April 24 in the Journal of Virologywhich is published by the American Society for Microbiology. In sharp contrast to the gastrointestinal distress it causes in humans, the murine mouse infecting norovirus plays a role in development of the mouse intestine and its immune system, and can actually replace the beneficial effects of certain gut bacteria when these have been decimated by antibiotics.

Normal, healthy gut bacteria help prevent infection by bacteria that cause gastrointestinal illness, but excessive antibiotic intake can kill the normal gut flora, and make one vulnerable to gastrointestinal disease. However, norovirus infection of mice actually restored the normal function of the immune system's lymphocytes and the normal morphology of the intestine, said Roossinck.

Mammalian viruses can also provide immunity against bacterial pathogens. Gamma-herpesviruses boost mice resistance to Listeria monocytogenesan important human gastrointestinal pathogen, and to Yersinia pestisotherwise known as plague. Latent herpesviruses also arm natural killer cells, an important component of the immune system, which kill both mammalian tumor cells, and cells that are infected with pathogenic viruses. The gastrointestinal tracts of mammals are plush with viruses.

So far, little is known about how these viruses affect their hosts, but their sheer number and diversity suggest that they have important functions, said Roossinck. For example, GI viruses that infect bacteria--known as phage--may modulate expression of bacterial genes involved in host digestion. Recent research shows that bacteriophage stick to the mucus membranes of many metazoans the class "Animalia," which includes everything from worms to wombats.

And mucus membranes, Roossinck points out, are the points of entry for many bacterial pathogens, suggesting that they provide the first line of defense against invading bacteria. Viruses also provide a variety of services for plants. A few plants grow in the hot soils surrounding the geysers and the "Artists' Paintpots" of Yellowstone National Park.

One such plant, which is a type of tropical panic grass, is a symbiosis that includes a fungus that colonizes the plant, and a virus that infects that fungus. All three members of this symbiosis are necessary for survival in soils simmering at more than degrees Fahrenheit. In the laboratory, Roossinck has created symbioses between the same virus-infected fungus and other plants.

This has enabled every plant her group has tested to survive at these elevated soil temperatures, including tomato, she says, noting that she has pushed the soil temperature to degrees without killing the computer screen went black how to fix. Investigators have also found that certain viruses can render some plants drought tolerant, and at least one example of virally-conferred cold tolerance has been discovered-- discoveries that could become useful for expanding the ranges of crops.

Plants are often infected with "persistent viruses" that are passed down from generation to generation, perhaps over thousands of years, with viruses that are transmitted to nearly percent of their plant progeny, but that have never been shown to be transmitted from one plant to another. Other beneficial viruses are the ancient retroviruses that long ago made a permanent home in the genome, or that left genes therein, said Roossinck.

I was always a little disturbed at the bad rap they get, so it was very exciting for me to find good ones. Materials provided by American Society for Microbiology. Note: Content may be edited for style and length. Science News. Journal Reference : Marilyn J.
