Discovery of pressure-driven infection mechanism opens door to new treatments for viral infections

The virus that causes those painful lip blisters known as cold sores has an internal pressure eight times higher than a car tire, and uses it to literally blast its infectious DNA into human cells, scientists are reporting in a new study.

CHOP-led research increases numbers of patients who could be treated with gene therapy

Gene therapy researchers have produced a bioengineered decoy that fools the immune system and prevents it from mistakenly defeating the benefits delivered by a corrective gene.

Researchers determine precise chemical structure of HIV capsid

Researchers have determined the precise chemical structure of the HIV capsid, a protein shell that protects the virus's genetic material and is a key to its ability to infect and debilitate the human body's defense mechanism.

Scientists move closer to understanding HIV-1 infection

Scientists have long been unable to fully explain how infections attack the body, but now a team of researchers, including one from the University of Central Florida, has taken a step closer to understanding how the process works in HIV-1. The results mean that one day that knowledge may prevent infection.

Newly characterized adenoviruses can cause severe human infections

The ongoing dance between a virus and its host distinctly shapes how the virus evolves. While human adenoviruses typically cause mild infections, recent reports have described newly characterized adenoviruses that can cause severe, sometime fatal, human infections.

Researchers develop new approach for HIV vaccine development

Decades of research and three large-scale clinical trials have so far failed to yield an effective HIV vaccine, in large part because the virus evolves so rapidly that it can evade any vaccine-induced immune response.

Findings provide structural basis for development of drugs to fight enterovirus 71 infection

New research findings may help scientists design drugs to treat a virus infection that causes potentially fatal brain swelling and paralysis in children.

New model of how the capsid of viruses assembles

A new model of the how the protein coat (capsid) of viruses assembles, published in BioMed Central's open access journal BMC Biophysics, shows that the construction of intermediate structures prior to final capsid production (hierarchical assembly) can be more efficient than constructing the capsid protein by protein (direct assembly).

Novira secures $23M in Series A financing to support antiviral development for HBV, HIV

Novira Therapeutics Inc. today announced it has secured $23 million in Series A financing to support the development of its capsid-targeting antivirals for the treatment of chronic hepatitis B (HBV) and HIV infections.

Bristol-Myers Squibb, Prosetta partner to discover and develop new antiviral drugs

Prosetta Antiviral Inc today announced the execution of a strategic alliance with Bristol-Myers Squibb Company to further discover and develop select drug candidates representing new, novel classes of antiviral drugs.

EBV can infect and may also contribute to lymphomas in man's best friend

More than 90 percent of humans have antibodies to the Epstein Barr virus. Best known for causing mononucleosis, or "the kissing disease," the virus has also been implicated in more serious conditions, including Hodgkin's, non-Hodgkin's and Burkitt's lymphomas. Yet little is known about exactly how EBV triggers these diseases.

Scripps Florida receives NIH grant to create novel HIV inhibitors

A Scripps Florida team has been awarded nearly $1.5 million by the National Institutes of Health to identify and develop novel potent inhibitors of the human immunodeficiency virus (HIV), the cause of AIDS.

Tetragenetics reports results from G-SOME H5N1 vaccine preclinical study

Tetragenetics Inc., a biotechnology company focused on the development of recombinant vaccines, today reported preclinical study results showing that an investigational nanoparticle-based influenza vaccine protects against a highly pathogenic H5N1 avian influenza strain.

IP-K and Sanofi form new HBV research collaboration

One of the most common and serious infectious diseases, Hepatitis B, is to be targeted in a new collaborative venture between the internationally-renowned translational research institute, Institut Pasteur Korea (IP-K), and the Korean arm of the leading global healthcare company, Sanofi-Aventis Korea. The goal is to develop and validate a high throughput assay to screen IP-K's chemical libraries for novel compounds that can be developed as new drugs.

Scientists define structure of astrovirus that causes juvenile diarrhea

Rice University scientists have defined the structure -- down to the atomic level -- of a virus that causes juvenile diarrhea. The research may help direct efforts to develop medications that block the virus before it becomes infectious.

Researchers identify altered expression of endogenous retroviruses in BSE-infected macaques

Prion diseases such as Creutzfeldt-Jakob disease in humans and bovine spongiform encephalopathy (BSE) in cattle are transmissible neurodegenerative diseases linked to the aggregation of the prion protein in the central nervous system.

Experimental vaccine against human norovirus generates strong, safe immune response in mice

Scientists have shown that an experimental vaccine against the human norovirus - the bug behind about 90 percent of highly contagious nonbacterial illnesses that cause diarrhea and vomiting - can generate a strong immune response in mice without appearing to cause the animals any harm.

Scientists determine protein structure that delivers genetic material of HIV to human cells

A team of scientists at The Scripps Research Institute and the University of Virginia has determined the structure of the protein package that delivers the genetic material of the human immunodeficiency virus to human cells.

Molecular interaction between structural HCV protein and protein critical to viral replication identified

Scientists from the Florida campus of The Scripps Research Institute have identified a molecular interaction between a structural hepatitis C virus protein (HCV) and a protein critical to viral replication. This new finding strongly suggests a novel method of inhibiting the production of the virus and a potential new therapeutic target for hepatitis C drug development.

Scientists find potential Achilles Heel in JC polyomavirus

The JC polyomavirus doesn't strike very often, but it's a mean bug that preys on people with weakened immune systems, including people with AIDS, and almost always kills them. Now an international team of scientists at Brown University, the University of T-bingen in Germany, and Imperial College in London has found a potential Achilles Heel and painted a target on it: The virus must bind to a very specific sugar molecule dangling from the side of the brain cells it attacks.
