Widespread antiviral drug use can accelerate the evolution of drug resistance in viruses

Influenza's ability to resist the effects of cheap and popular antiviral agents in Asia and Russia should serve as a cautionary tale about U.S. plans to use the antiviral Tamiflu in the event of widespread avian flu infection in humans, scientists say.

Bird flu becoming more resistant to antivirals

A new University of Colorado at Boulder study shows the resistance of the avian flu virus to a major class of antiviral drugs is increasing through positive evolutionary selection, with researchers documenting the trend in more than 30 percent of the samples tested.

Scientists isolate genes that made 1918 flu lethal

By mixing and matching a contemporary flu virus with the "Spanish flu" - a virus that killed between 20 and 50 million people 90 years ago in history's most devastating outbreak of infectious disease - researchers have identified a set of three genes that helped underpin the extraordinary virulence of the 1918 virus.

Scientists show that HIV's evolution in the body does not occur at a constant rate

HIV is so deadly largely because it evolves so rapidly. With a single virus as the origin of an infection, most patients will quickly come to harbor thousands of different versions of HIV, all a little bit different and all competing with one another to most efficiently infect that person's cells. Its rapid and unique evolution in every patient is what allows HIV to evade the body's defenses and gives the virus great skill at developing resistance to a pantheon of antiviral drugs.

Hep C treatment pegylated interferon reduces the virus but liver damage continues

Treating patients who have chronic hepatitis C and advanced liver disease with long-term pegylated interferon significantly decreased their liver enzymes, viral levels and liver inflammation, but the treatment did not slow or prevent the progression of serious liver disease, a study finds.

Interferon as long-term treatment for hepatitis C not effective

Use of the drug interferon as a long-term maintenance strategy to slow the progression of liver disease associated with the hepatitis C virus is ineffective, UT Southwestern Medical Center researchers and their colleagues from nine other institutions have found in a multicenter study.

Liver disease tackled with dedicated unit at Imperial College London

Liver disease death rates are rising in the UK, in contrast to other common diseases such as heart disease and cancer, and the new Robert Hesketh Hepatology Clinical Research Facility aims to provide care and develop new therapies to reverse this trend.

Scientists find key to keeping killer T cells in prime shape for fighting infection, cancer

Like tuning a violin to produce strong, elegant notes, researchers at The Wistar Institute have found multiple receptors on the outside of the body's killer immune system cells which they believe can be selectively targeted to keep the cells in superb infection- and disease-fighting condition.

Children born four months before height of cold and flu season have a greater risk of developing childhood asthma

It is said that timing is everything, and that certainly appears to be true for autumn infants.

Protein transporter in the gut could speed drug 'take up'

For poorly absorbed medications, drug makers should consider using natural homing devices to drive the drugs through the hazards of gastrointestinal acidity and enzymes to reach the bloodstream quicker, James Polli, PhD, said today at the annual meeting of the American Association of Pharmaceutical Scientists (AAPS) in Atlanta.

Scientists discover new cause of fatal brain injury from acute viral meningitis

In a November 16 advance, online publication of the journal Nature, the researchers say their discovery revamps common beliefs about how such potentially lethal infections may be ravaging the brain and suggests the possibility of new treatments.

New research reveals key steps in HIV's assault on the brain

Scientists have unraveled in unprecedented detail the cascade of events that go wrong in brain cells affected by HIV, a virus whose assault on the nervous system continues unabated despite antiviral medications that can keep the virus at bay for years in the rest of the body.

Genetic Immunity announces first patient dosed in trial with DermaVir patch for HIV

Genetic Immunity, a US/Hungarian clinical-stage company focused on development of nanomedicines for targeted immune amplification, today announced it has treated the first subject in a Phase II clinical study to evaluate DermaVir Patch.

Astragalus root plant chemical used to fight HIV

Like other kinds of cells, immune cells lose the ability to divide as they age because a part of their chromosomes known as a telomere becomes progressively shorter with cell division.

H5N1 protein hides in tiny tubules

A protein found in the virulent avian influenza virus strain called H5N1 forms tiny tubules in which it "hides" the pieces of double-stranded RNA formed during viral infection, which otherwise would prompt an antiviral immune response from infected cells, said Baylor College of Medicine researchers in an online report in the journal Nature.
