Researchers reveal 3-D structure of bullet-shaped virus with potential to fight cancer, HIV
Vesicular stomatitis virus, or VSV, has long been a model system for studying and understanding the life cycle of negative-strand RNA viruses, which include viruses that cause influenza, measles and rabies. view more (2010-02-09)
Carnegie Mellon first to measure energy released from a virus during infection
For the first time, Carnegie Mellon University physicist Alex Evilevitch has directly measured the energy associated with the expulsion of viral DNA, a pivotal discovery toward fully understanding the physical mechanisms that control viral infection and designing drugs to interfere with the process. view more (2010-02-08)
Iowa State, Ames Lab chemists discover how antiviral drugs bind to and block flu virus
Antiviral drugs block influenza A viruses from reproducing and spreading by attaching to a site within a proton channel necessary for the virus to infect healthy cells, according to a research project led by Iowa State University's Mei Hong and published in the Feb. 4 issue of the journal Nature. view more (2010-02-04)
Preventive program associated with reduced spread of H1N1 at summer camp
A targeted program of preventive antiviral medication, combined with the use of hand sanitizers and surface decontamination, was associated with containing the spread of the H1N1 virus in a summer camp setting. view more (2010-02-02)
Tobacco plant-made therapeutic thwarts West Nile virus
A new therapeutic made from tobacco plants has been shown to arrest West Nile virus infection, according to a new study by Arizona State University scientist Qiang Chen and his colleagues. view more (2010-02-02)
Of swine, birds and men -- pandemic H1N1 flu
Current research suggests that pandemic H1N1 influenza of swine origin has distinct means of transmission from the seasonal flu, yet does not result in the pathogenic severity of avian flu viruses. view more (2010-02-02)
Virus pulls bait and switch on insect vectors
A common plant virus lures aphids to infected plants by making the plants more attractive, but when the insects taste the plant, they quickly leave for tastier, healthier ones. In the process, the insects rapidly transmit the disease, according to Penn State entomologists. view more (2010-02-02)
Researchers find 'broad spectrum' antiviral that fights multitude of viruses
Viruses are insidious creatures. They differ from each other in many ways, and they can mutate - at times seemingly at will, as with HIV - to resist a host of weapons fired at them. Complicating matters further is that new viruses are constantly emerging. view more (2010-02-02)
Virus-like particle vaccine protects monkeys from chikungunya virus
An experimental vaccine developed using non-infectious virus-like particles (VLP) has protected macaques and mice against chikungunya virus, a mosquito-borne pathogen that has infected millions of people in Africa and Asia and causes debilitating pain, researchers at the National Institutes of Health have found. view more (2010-01-29)
Immune memory formation seen in early stages of viral infection
In an acute viral infection, most of the white blood cells known as T cells differentiate into cells that fight the virus and die off in the process. But a few of these "effector" T cells survive and become memory T cells, ensuring that the immune system can respond faster and stronger the next time around. view more (2010-01-29)
Scripps research scientists find potential new way to enhance vaccines
Researchers at The Scripps Research Institute have discovered a potential new way to stimulate the immune system to prevent or clear a viral infection. view more (2010-01-28)
Deadly fish virus now found in all Great Lakes
A deadly fish virus that was first discovered in the Northeast in 2005 has been found for the first time in fish from Lake Superior, report Cornell researchers. That means that the virus has now been documented in all of the Great Lakes. view more (2010-01-28)
Control of herpes symptoms does not reduce HIV transmission, international study found
Research from a five-year international clinical study shows that acyclovir, a commonly prescribed drug used to suppress symptoms of the herpes virus, does not affect HIV transmission by people with both viruses. view more (2010-01-26)
New Compound Could Be Alternative Strategy for Preventing HIV Infection
With the help of effective drug therapies, HIV patients are living longer, healthier lives. Now, researchers want to improve these drug therapies and develop alternative preventative strategies, such as vaginal gels and creams that contain the same or related compounds used in treatments for people infected with HIV. view more (2010-01-26)
Study Shows Genital Herpes Virus Reactivates Widely Throughout Genital Tract
Genital herpes caused by a reactivation of herpes simplex virus type 2 (HSV-2) is generally treated as a lesion in one specific area of the genital region. A new study, however, finds that the virus can frequently reactivate throughout the genital tract, an important new concept that could help guide both HSV-2 treatment and prevention. view more (2010-01-25)
Video of virus in action shows viruses can spread faster than thought possible
New video footage of a virus infecting cells is challenging what researchers have long believed about how viruses spread, suggesting that scientists may be able to create new drugs to tackle some viruses. view more (2010-01-22)
Double trouble: Bacterial super-infection after the flu
Current research suggests that the flu may predispose to secondary bacterial infections, which account for a significant proportion of mortality during flu pandemics. view more (2010-01-22)
Iowa State University researcher discovers Ebola's deadly secret
Research at Iowa State University has led scientists to uncover how the deadly Zaire Ebola virus decoys cells and eventually kills them. view more (2010-01-20)
Early immune response needed for hit-and-hide cancer viruses
Retroviruses such as HIV and HTLV-1 don't hit-and-run, they hit-and-hide. They slip into host cells and insert their own DNA into the cell's DNA, and from this refuge they establish an infection that lasts a lifetime. view more (2010-01-15)
The viruses within -- and what keeps them there
It is known that viral "squatters" comprise nearly half of our genetic code. These genomic invaders inserted their DNA into our own millions of years ago when they infected our ancestors. But just how we keep them quiet and prevent them from attack was more of a mystery until EPFL researchers revived them. view more (2010-01-14)
